William Herschel's Double Star Catalog
   The following list has been compiled from the Herschel catalogues edited by John Herschel and subsequently by John Dreyer for the Royal Astronomical Society. Thanks to P.J. Anway for providing me with the catalogs in pdf format. All binary data have been drawn from the November, 2010 Washington Double Star Catalog (WDS). Herschel's notes are reprinted for their historical value and to confirm or question my attributions to modern catalog identifications.

   I have omitted his position angle and separation measurements for pairs closer than 15", as his methods at close separations were not reliable and he sometimes gives multiple or inconsistent values. (See for example the extended comments on separation and ocular magnification under H I 28.) Separations and position angles are quoted for wider systems, in square brackets to show they have been converted to modern units (e.g., "40° south following" is quoted as [PA = 130°]). Measurements described by Herschel as unreliable or approximate are preceded with a tilde (~).

   In Herschel's descriptive notes "L." and "S." refer to the primary (larger) and secondary (smaller) stars respectively; "size" means magnitude (size of diffraction disk). His gradations of magnitude differences (from least to greatest) are: (0) equal, (1) a little unequal, (2) pretty unequal, (3) considerably unequal, (4) very unequal, (5) extremely unequal and (6) excessively unequal. In the color notes, "w" = white, "r" = red, "b" = blue, "p" = pale, "d" = dusky, dim or dark. Note that after July 1782 his color notes become more cursory and over time he shifts from listing only Flamsteed/Bayer numbered objects to using these labeled stars as signposts to unmarked multiple stars.

   Herschel often relies on the iconography of Flamsteed's Atlas Cœlestis to locate stars: for example, "under the left foot" of Bootes or "under the tail end" of Draco. To interpret these references, I have used the online copy of Francis Baily's 1835 edition of Flamsteed's British Catalogue of Stars available at Google Books, Jean Fortin's 1779 edition of Flamsteed's Atlas Céleste furnished online by the Linda Hall Library of Science, Engineering & Technology, and Morton Wagman's article "John Flamsteed's Missing Stars" available at the SAO/NASA Astrophysics Data System.

It is the brightest star due south of 119 Tau and due west of 122 Tau. The unusual "almost equal" description of the relative magnitudes, and the lack of star hopping directions, make this identification uncertain; but the measurements match almost exactly.

It is one of a cluster of six telescopic stars, arranged in pairs.WDS assigns the label H II 37 to a star near 12 Mon (within the Rosette Nebula), but the row of six paired stars just south of 15 Monocerotis, in the Christmas Tree cluster, also fits the description, and contains a delightful and delicate 9th magnitude double, in addition to the triple H III 46 just north. (In Fortin's 1776 edition of Flamsteed's Atlas Cœlestis, 12 Mon is under the chin, 15 Mon is behind the ear.)

More in view.There are only two candidates within 10' north preceding gamma Geminorum that are within the class and have companions brighter than magnitude 12: FOX 147 (magnitude 6.2) and ARN 103 (magnitude 9.2). Given the description of this star at the duplicate entry (H VI 91), I've chosen the fainter pair. It's possible that Herschel meant an optical pair uncatalogued in WDS in this area where there are "more in view".

(†Observed by different astronomers before Mr. Mayer. — Herschel's footnote.) The note is quoted in full to illustrate Herschel's method of measuring rho (separation) and the difficulty of interpreting his results. Herschel understood that the Airy disk was "largely spurious" but believed in some cases the actual disk of a star could be glimpsed; hence the high magnifications, which result in exit pupils of 0.10 mm at 1536x and 0.05 mm at 3168x. Herschel knew that the Airy disk changes in relative size as magnification is increased or as aperture is stopped down, a procedure he sometimes used, apparently without comment in his notes, to control the effects of poor seeing. With the methods available to him, the measurement of rho to thousandths of a second and theta to single minutes of an arc is only the numerical result of averaging two or more measures.

The reference description matches the attributed star location, magnitude difference and nearby stars, and Herschel reserves the phrase "a considerable star" for stars of 6th mag. or brighter. One problem: the separation (= class V) is grossly outside this class. The alternative, STF 1127 (rho = 5.2" in Herschel's time) is 4° n.p. 57 Cam along the same line, about 1-1/2° south of 51 Camelopardali, and magnitude 7.2.

It will at first sight appear as only a double star, but with proper attention, and under favorable circumstances, the preceding of them will be found to consist of two stars, which are considerably unequal. The largest of these is larger than the single star; and the least of the two is less than the single star. The first and second (in order of magnitude) pretty unequal. The second and third pretty unequal. The two nearest both pale r. or r. For measures relating to the third or single star see zeta Cancri in the third class of double stars [H III 19].Herschel often describes F stars as pale red, reddish, or inclining to red. He never uses the term "yellow", "golden" or orange to describe star color. I suspect he may have been colorblind, which would also explain why his magnitude estimates are often divergent from those of other observers or modern methods. Note that he discovered this was a triple system 18 months after first identifying it as a binary.

Both w.An "n Ursae majoris" is not listed in Flamsteed; checking Flamsteed's charts it is probable that HIP 44700 is intended. In that case there is a problem solving the instructions: the sole binary south of 36 Lyn is not on the parallel from 31 Lyn and is the farther of two stars from 31 Lyn; assuming Herschel transposed 31 and 36 in the instructions gives a binary south of 31 and closer of two to 36 that fits the catalog, but not on a parallel from 36: both binaries are at least 1° distant from the reference star, and Herschel is rarely that far off in his finder or field separation estimates. I suggest Herschel has mislabeled stars, and the directions should read: "Near 1/2 degree s. following the 35th Lyncis, in a line parallel to the 36th Lyncis and n Ursae majoris; of two the nearest to the 35th Lyncis."

However the "end of the tail" in Fortin's image of the Lynx is at 38 and 40 (alpha) Lyncis; and Herschel may have believed by proximity that his reference star 41 Lyncis was HIP 47029 (see note to H IV 30). Resorting in this confusion to a brute force search of the entire area containing all possible reference stars yields STF 1342 as the best match to Herschel's magnitude description and positional measurements. It is 2.8' north following 40 Lyncis.

The diameters [separation] are so small that the length of the time, and attention of looking, makes a considerable difference in the estimation of the distance.A conjectural attribution that matches Herschel's description. The binary is in the correct relation to a unlabeled 5.5 mag. star, which is about 4° SE of CS Ursae majoris, the star identified as 44 Lyncis by precessing the coordinates given in Flamsteed's catalog. However that star is brighter than 5.5, the magnitude Flamsteed gives for 44 Lyncis, and several of Baily's endnotes indicate a very confused state of measurement and labeling in this part of the sky.

What "bend a little towards psi" means is unclear, but assuming that it directs attention SE or S, I nominate STF 1428, whose separation fits the class.

The description matches xi Sco (STF 1998), which appears in the same field with STF 1999, and xi Sco is a treble star, the closer pair separated by 0.7" (conforming to Class I). The slip may have happened because xi Sco lies closer to the asterism of Libra than to Scorpius and very near the border between them.

L. fine brilliant w.; S. dusky [Rho = 38", PA = 117°] (Note added 10/22/1781: Having often measured the diameters of many of the principal fixed stars, and having always found that they measured less and less the more I magnified, I fixed upon this fine star for taking a measure with the highest power I have yet been able to apply, and upon the largest scale of my new micrometer I could conveniently use. With a power of 6450 (determined by experiments upon a known object at a known distance) I looked at this star for at least a quarter of an hour, that the eye might adapt itself to the object; having experimentally found, that the aberration by this means will appear less and less, and, in the telescope I used upon this occasion with powers from 460 to 1500, will often quite vanish, and leave a very well-defined circular disk for the apparent diameter of the stars. The diameter of alpha Lyræ, by this attention, appeared perfectly round, and occasionally separated from rays that were flashing about it. From the very brilliant appearance of the star with this great power, and a pretty accurate rough calculation founded on its apparent brightness, when observed with the naked eye, with 227, with 460, with 6450, I surmise, that it has light enough to bear being magnified at least a hundred thousand times with no more than six inches of aperture, provided we could have such a power, and other considerations would allow us to apply it. When I had as good a view as I expected to have, I took its diameter with my new micrometer upon a scale of eight inches and 4428 ten thousandth to 1" of a degree, and found it subtended an angle of 0".3553. I had no person at the clock; but suppose the time of its passing through the field of my telescope (which in this great power is purposely left undefined, and as large as possible) was less than three seconds.) WDS tallies 14 components in the Vega system, all but 3 of them v.mag. 15 or fainter; these are field stars included for the micrometer measurement of Vega's proper motion. — Herschel's extensive observing notes merit scrutiny. The visual adaptation procedure was intended to minimize (chromatic?) "aberration", but perhaps also habituated the eye to the Airy disk motions caused by seeing. The "undefined" field was produced by Herschel's tiniest spherical lens eyepieces, which had no field stop; a Vega transit of 2.5 seconds ("less than 3 seconds") implies a useable field of view of just 30". With his 157 mm "7 foot" (f/13) reflector, a magnification of 6450 implies an eyepiece focal length of 0.32 mm and an exit pupil of 0.02 mm! In his Making Your Own Telescope (1948, p.16), Allyn Thompson reports the posthumous discovery and measurement by W.H. Steavenson of several eyepieces among Herschel's effects: the smallest had a focal length of 0.28 mm and no eye relief, so the high magnifications cited by Herschel are credible. However the theoretical diameter of the Airy disk in Herschel's full 157mm aperture would be about 1.76", almost five times larger than the measurement taken, but his claim that the disk gets smaller as magnification increases is consistent with other observations (for example, of epsilon Lyræ) and is probably the result of attenuation of the disk luminance by magnification, which causes its apparent diameter to contract toward the central peak luminance. This complicates Herschel's practice of using various magnifications to estimate binary separation (rho), or any distance estimates not established with a micrometer — which also delivers unreliable measurements when used at extremely high magnifications (as it was here). Herschel's practice of quoting distance estimates to the thousandths of an arcsecond reflects his interest in discovering very small proper motions and parallax effects, although accuracy that extreme was not possible with his instruments and methods.

Herschel's notes are inadequate to identify a specific star; the discovery date is also out of sequence. I've supplied STF 2368 (rho = 1.9") as best matching his catalog criteria in the southeasternmost area of Draco most convenient for observation in September, but STF 2438 is also plausible. I conjecture that STF 2438 is near omicron Draconis, so would have been located in reference to it; STF 2368 is farther from a labeled star and among many brighter stars, so a positioning explanation would have been more complex to work out: night fatigue, vague morning recall or exasperation with Fortin's cartography would have deflected Herschel from details.

Where Herschel provides no exact star location directions, I proceeded as follows. I first defined a plausible target area of sky around the locator star (in this case, the area RA 20 04 to 2014, Dec. 35° to 38° around 28 Cygni), sorted entries in WDS and within that sky area to eliminate pairs where either star is below magnitude 11.0 (generally the lower limit of stars identified in his other catalogs), then sorted again to identify stars matching in magnitude difference, position angle or separation (if possible, whenever Herschel provides them). In this case, the procedure finds 6 candidates with separations between 60" to 90". The closest matching in separation (ABH 129 AF at 71") is rejected because both stars are magnitude 11. Instead I chose SHJ 316 (rho = 70"), an 8th magnitude pair, on the grounds that the James South & John Herschel catalog (SHJ) incorporates many stars from Williiam Herschel's prior inventory, and that only stars this bright would appear remarkable against the Cygnus Milky Way background. And while the star is actually much closer to 27 than to 28 Cygni, the stars 27, 28 and 29 were known in Herschel's time as b1, b2 and b3 Cygni respectively. In any case, when such methods and inferences are involved, I mark the attribution as doubtful.

Considerably unequal. Position nf. 1st class. The angle is such, that a line continued and met by one from the other star, so as to make an isosceles triangle, would meet the line of position at a little more than twice the distance of the two large stars. I verified it with 460 [magnification], after having looked a considerable time with 920, by way of getting the eye in order. A division can hardly be perceived. But the situation [altitude] is so low, that certainly the greatest difficulty of seeing the stars arises from that cause. Both together might conveniently stand between the two stars of zeta Aquarii, and leave a considerable interval on each side.In Herschel's 6.5" f/13 telescope, the powers cited correspond to eyepiece focal lengths of 4.6mm and 2.2mm, respectively. This is actually the BC component of the triple system catalogued as H VI 119.

[Rho = ±135"]3 Cassiopeia, Herschel's original attribution, is one of Flamsteed's many "missing" (mismeasured, mislabeled) stars — in this case explained by some scholars as a dimming supernova. An exhaustive search in WDS of the area from RA 23 00 to RA 23 25 (= 4 Cas), Dec. 53° to 64° yields 2 Cas as the most likely candidate: the separation is roughly correct, and the James South catalog incorporates many of Herschel's VI stars.

[PA = 216°] Distance of the largest of the two from upsilon Coronæ 1'18"8'". Position of the same with upsilon, 64°24' n. following.See note at H V 37. The PA 26° probably refers to the AC pair (C magnitude 10.4), and PA 216 to the BC pair (B magnitude 11.7).
H III 59near 19Perduplication= H III 36In capite [in the head (of Perseus)]. Double. It is perhaps the 19th Persei removed, or more likely a star not marked in FLAMSTEED'S Catalogue; the 19th being either vanished, or misplaced by FLAMSTEED. Pretty unequal. Distance 12" 2'". Position 0°0' following. L. bw.; S. br.19 Persei does not exist, according to Wagman, due to a reduction error by Flamsteed. Herschel's comments imply he is thinking of a near visible or visible star (magnitude 7 or greater) with components differing little in magnitude. STF 331 is also in the head of Fortin's image of Perseus and matches Herschel's measurements.
H N 124near 15Oriduplication= H III 931/21/18001093 Sweep. Double, 9.9 m. 2d or 3d class. 15 Orionis f. 22' 24", n. 1° 33'.Herschel's magnitude description does not match the attribution, but the location from 15 Orionis, confirming the duplication, is exact.
H IV 46[20]Gemduplication= H IV 2812/27/1781Double. A little unequal. Both pr. [Rho = ±25"]Herschel identifies the star as either 20 or 21 Geminorum; Dreyer supplies the correction. The confusion creating the duplication may have arisen because "the 21st and 20th Geminorum are not in the heavens as they are marked in Flamsteed's Atlas, so that it becomes doubtful whether the No.21 is right" (Herschel's note).
H IV 116*near 83Pegduplication = H IV 91/13/1783Sequens ad austrum [south following]. Double. Equal. [Rho = 29", PA = 158°] Both w. Mr. C. MAYER, in 1777, settled its place RA 0h.52'53" in time, and 20°17'53" in declination N. (*Observed by Mr. MAYER and other astronomers. — Herschel's footnote.)Mayer records no star in Pegasus. Dreyer's note: "It is = IV.9, psi Piscium."
H IV 128near 57gammaAndduplication= H IV 1047/28/1783Double. About 1-1/3 degree s. preceding gamma almost towards beta Andromedæ; more exact towards sigma Piscium; one not in a row of stars which are near that place. Considerably unequal. L. pr.; S. dr. [Rho = 16", PA = 66°]
H V 51nearepsilonSgeduplication= H N 8411/23/1781Double. It is a star north following epsilon. Extremely unequal. [Rho = 33"] L. r.; S. blue.
H V 5615Gemduplication= H V 521/30/1782Dextrum prioris II pedem attingens [Touching the right foot of the first Twin]. Double. Considerably or very unequal. L. r.; S. d. [Rho = 33", PA = 210°]This duplication with H V 52, entered just five weeks earlier, illustrates the poorly edited condition of Herschel's catalogs and perhaps also the hectic and tiring pace of his observational work.
H V 113*near 11Oriduplication= H V 5712/7/1782Treble. About 1-1/2 degree s. preceding the 11th Orionis, towards iota Tauri. The two largest considerably unequal. L. w.; S. pr. [Rho = 38", PA = 304°] The third farther off and smaller. S. r. Position n. following.Confused entry. 105 (iota) Tauri is north following 11 Orionis, so a star in that direction cannot be south preceding. Herschel's positional measurements match the attribution (a duplication of H V 57); perhaps omicron2 Orionis was the intended reference star.
H VI 9124gammaGemduplication= H V 714/15/1782Double. Three or four minutes n. of gamma Geminorum. Considerably unequal. Both small; too obscure for measures with 7-feet; my 20-feet shews a third star between them with [stopped down to] 12 inches aperture.
H VI 89near 6Booduplication= H VI 153/12/1782Double. Just following the 6th Bootis. A little unequal. L. r.; S. deeper r. [Rho = 80", PA = 212°]The measurements here match H VI 15 nicely; the separation estimate there is considerably off, but the location instructions seem unambiguous.
H N 95Aqlduplication= H III 337/22/1784243 Sweep. 5 Aquilæ, treble, the 3d excessively small. Position following the other two, the line bending a little towards the south. Distance almost the same from the 2d, as the 2d from the 1st. — (Review. 8/5/1796) 5 Aquilæ, treble. Distance of the largest and next to it 0 rev. 24.5 parts + 4-1/2 for zero = 11.9". Position 2 rev. –61.3 parts + 1.1 for zero = 31° 27.3', considerably unequal. The 2d and 3d very unequal. The 1st and 3d extremely unequal. sf. The 3d is more sf. still, and requires some attention to be seen. Lw. S. dr. 3d very obscure; 460 shows it better than a lower power.
H N 40duplication= H N 65/26/1786566 Sweep. A double star within neb. IV. 41. 14 Sagittarii p. 11' 58", s. 1° 15'.IV. 41 = M20, NGC 6514

H VI 27nearthetaAqlduplication= H V 1368/24/1780Double. It is a star north of theta. [Rho = ±60"]Superseding the attribution in WDS labeled H VI 27, which has a separation of 135" and a magnitude 13 (!) companion, and identifies theta Aquilæ itself, not a star "north of" it.
H N 114duplication= H VI 1044/5/1796Journal. 7-feet reflector, power 460. (zeta) Bootis, double, 1st class. Very nearly in contact; I can however see a small division. A little unequal, the preceding is the smallest. — (Review. 8/6/1796) zeta Bootis, double. Position 2 rev. –14.5 parts +1.1 for zero = 41' 59.1" np. With 460 a division is but barely visible 1/4 of S. Both w. A little, or pretty unequal. — (Review. 7/12/1807) zeta Bootis. They are fine, equal, whitish stars: the interval between their apparent disks with 460 is 1/3 of the diameter of either.
H N 12867Aqrduplication= H N 1339/7/1801Review. 67 Aquarii, double, 1st class.67 Aquarii is not double, and no celestial coordinates are provided. Herschel has apparently mistaken it for STF 2935, of identical magnitude but 1.5° south, which matches the description (see H N 133).
H I 1117[beta]CncunidentifiedDouble. Considerably unequal. Both pale r.Herschel cites 17 beta Cancri, but no catalog lists that as a double star.
H III 31In constellationeHerunidentified5/20/1781Double. Over iota Herculis. Equal. Both very small.Dreyer's note: "Over iota Herculis toward gamma [Draco]. Not sure that the letter iota is right. Cannot be identified." I cannot find in WDS a binary system north of iota Herculis as far as gamma Draconis that fits the description "equal ... very small" (faint).
H III 8440Lynunidentified11/13/1782Propre ... in Ursæ majoris pede [Specifically in the foot of Ursa Major]. Double. Very or extremely unequal. L. wr.; S. r. Dreyer's note — "The larger star is not 40 Lyncis, but is 3' north following it" — refers to a field diagram. 40 alpha Lyncis is about 12° south of the Bear's "foot" (kappa and tau UMa) and is not a binary star. There are no star hopping directions. Assumed lost.
H III 107Congerie Stellularum
Sagittarii borealior
Sgrunidentified6/6/1783Double. Above 1-1/4 degree n. of the 20th cluster of stars of the Connoissance des Temps, in a line parallel to gamma Sagittarii and the cluster: the most south of many. Considerably unequal. Distance with 278, 15", as accurate as the prismatic power of the atmosphere, which lengthens the stars, will permit. Position 54° 48' s. preceding. [PA = 216°]A line from gamma Sgr through M 20 (Trifid Nebula) is roughly NNW: I find no candidate binaries 1-1/4° north of M 20 that resemble his measurements. I conjecture that Herschel may have meant south of M 20, which locates M 8 (the Lagoon Nebula) exactly, and that the stars of M 8 are the "many" he saw, perhaps not observing the nebula around M 8 due to its very low altitude (which Herschel remarks on). But there are no stars in WDS that match his measurements, and I cannot locate an obvious candidate "most south" in photographs of the cluster or in Stellarium.
H IV 1631Casunidentified8/2/1780Double. It is marked with the letter A in HARRIS'S maps. [Rho = ±20"]31 Cas, specified by Herschel, is not a double. A possible confusion object, psi Cas, is clearly labeled in Fortin and catalogued by Herschel as H V 83. Note also the confusion at H IV 65, and within Perseus, Cassiopeia and Cepheus in general. Assumed lost.
H V 1516cUMaunidentified5/2/1780Double. Very unequal. L. whitish r.; S. d. [Rho = 49", PA = 190°]The star 16 Ursæ majoris is not a double in any catalog I have consulted. There is no star within 15° of 16 UMa that even approximately matches Herschel's precise measurements and the 5th magnitude of the attributed star.
H V 45neartauCygunidentified10/1/1781Double. It is the most south of two telescopic stars following tau. Very unequal. L. w.; S. d. [Rho = 44"] Position — following.The only star in WDS within 2° following tau that reasonably matches the description is S 790 (H V 44).
H V 94near 31Cepunidentified9/30/1782Double. About 3/4 degree n. of the 31st Cephei, towards alpha Polaris [sic]. Pretty unequal. Both pr. [Rho = 42", PA = 135°]Bizarre entry: "north" is toward Polaris! Worse, there is no star within 2° north preceding or following 31 Cephei that matches the class.
H VI 19chiPerunidentified8/2/1780Multiple. An astonishing number of small stars all within the space of a few minutes. I counted not less than 40 within my small field of view.Obviously it isn't possible to identify a specific binary for this entry, given Herschel's vague description and the crowded field in the eastern half of the Double Cluster (chi/h Persei). Ironically, the WDS lists no binary system in chi Persei that matches the class separation (> 60").
H VI 45near iotaAndunidentified7/21/1781Double. It is a star near iota towards omicron. L. r. [Rho = ±90"]I cannot find anything between RA 23 00 to 23 40, Dec. 42° to 44° and above magnitude 11 that corresponds to Herschel's measurement.
H VI 55near 2eCasunidentified9/6/1781Double. It is a star near e. L. r. [Rho < 150"]I can find no double star fitting Herschel's class VI between 2 Cas and AR (e1) Cas.
H VI 60nearc2Cygunidentified10/8/1781Double. It is a star near the second c. Considerably unequal. L. w.; S. d. [Rho = 88"]In his edition of Flamsteed's British Catalogue of Stars, Francis Baily notes that c2 Cygni does not exist, and is a mislabeling of Bayer's original e Cygni — Flamsteed's 26 Cygni, catalogued by Herschel as H V 47. Dreyer states that the double star cannot be identified, and I also cannot find anything in WDS within 3 degrees of 26 Cygni that resembles Herschel's magnitude difference and stated separation.
H VI 63nearepsilonSgeunidentified10/12/1781Double. It is the star north following epsilon. Extremely unequal. L. w. inclining to r.; S. d. [Rho = 91", PA = 266°] A third star in the same direction, at a little more than twice the distance. A fourth star in view.
H VI 10922phiCncunidentified12/29/1782Double. One of the two being lost, it does not appear which is the remaining star. Very unequal. L. r.; S. dr.
H N 4near 51xiLibunidentified5/9/1784210 Sweep. About 18' south of 51 (xi) Libræ, double 3d class far.The stated separation seems too large to be a duplication of H II 21.
H N 76near 65iPscunidentified12/2/1790983 Sweep. 7 m., double, extremely unequal. [PA = ±170°], 2d class, very near. 65 (i) Piscium p. 16' 53", n. 0° 34'.65 Piscium is itself a close, equal binary (STF 61). However there is no binary matching Herschel's description at either his positional location (including transposed directions) or his precessed celestial coordinates.
H N 78unidentified3/24/1791999 Sweep. Treble, the two largest equal, 3d class. The first star very small, north preceding the other two; a little further from the preceding of the two, than they are from each other. (RA By the sweep 11h 37' : :, PD 121° : :, no star in the sweep to settle its place.)I cannot find in WDS any matching triple system (primary magnitude 10 or greater, brightest two components within 1 magnitude, separation 5" to 15") within 10 degrees of Herschel's coordinates precessed to J2000 (RA = 11h 47', Dec. = –20.1). The two most plausible, STF 1474 and STF 1669, do not match his description of the configuration: both have a very close pair and a third star at much greater distance.
H N 82near 8etaBoounidentified4/20/17921021 Sweep. Double, equal, 4th or 5th class. 8 (eta) Bootis f 7' 24", n. 0° 58'. — (Review 8/6/1796) I cannot find the double star of the 1021 sweep 7' 24" following eta Bootis.

Position directly preceding [PA = 270°] 7m. 4 (epsilon) Sagittæ p. 2' 57", s. 0° 11'. — (Review 10/17/1795) I cannot see the small star of the double star in the 1024 sweep observed at 19h 25' 33". — (Review 8/7/1796) I cannot see the small star of the double star in the 1024 sweep observed at 19h 25' 33", with the 7-feet telescope. I see a very small star following 6th class, but the star I look for should be preceding.
H N 102near 31omicronAqrunidentified9/28/17931054 Sweep. Double, equal, 3d class. Position from np. to sf. but nearer the parallel. 31 (omicron) Aquarii f. 12' 41", s. 0° 47'.Nothing in either Millennium Star Atlas or WDS at Herschel's location from 31 Aquarii, which matches his coordinates precessed to J2000.
H N 113near 15Cygunidentified11/9/1795Journal. A small telescopic star nf. 15 Cygni, double, 2d class, very unequal. It is about 5' or 6' from 15 Cygni, and its position with [115] is 4 rev. –37 parts –23.2 for zero = 71° 55'. — (Journal. 12/30/1795) The small double star north following 15 Cygni follows it 17.5" in time: 7-feet reflector, power 115.Nothing corresponding (rho = ±5") in WDS or shown in MSA within the stipulated distance of 15 Cygni.
H N 130near 51muCapunidentified9/12/1801Review. Double, 1st class. It is a small star, equally distant from d and mu Capricorni, but a little more south than either. It is a little nearer mu than d.d Capricorni is not found in any catalog available to me, and Herschel provides no celestial coordinates. I cannot find a star near to, west and slightly south of mu Capricorni that matches the "small" (faint) 1st class (rho < 5") description.
