WDS gives the pair as position angle: 275, Sep: 2.0, Burnham at position angle: 300, Sep: 1.1, and lists the separation as "decreasing". It could well be under an arc second.

| STF 661 | 5h 13m 13.86s | -12° 56' 26.4" | B | C-8 | 2008/Feb/16 20:15:00 | This double was hard to see. The companion was invisible in the 24.5 (83x),but it was plain the the 8.8 (231x). Although the separation was 3.1",the primaries light (4.4 mv) enveloped the secondary (6.8 mv). WDS data: 4.43 - 6.77mv, B9V, 357° pa, 2.2", 2008. |

It looks as if it shines by reflected light, and seems almost grey, although it is a B9 star. A bright companion can strongly influence one's perceptions of the secondary.

Aladin: The proper motion in declination delta is close, 2 mas/yr, but that is right ascension is huge, 70 mas/yr. It looks optical. WDS data: 6.61 - 9.21mv, A2VGIII, 182° pa, 23.1", 2012. |

| STF 696 | 5h 22m 50s | 3° 32' 40" | B | C-8 | 2006/Nov/03 03:30:00 | AKA 23 Ori. Nice. The primary shows a faintly pastel green tint about it. WDS data: 4.95 - 6.76mv, B1V, 30° pa, 31.5", 2009. |
| STF 700 | 5h 23m 5.53s | 1° 3' 24.69" | B | C-8 | 2007/Jan/10 21:00:00 | A pretty pair of white stars, with that special brilliance from the fact they are B9s. WDS data: 7.69 - 7.89mv, B9VB9.5V, 5° pa, 4.9", 2002. |

In the 24.5, there are a line of stars: 7.5 10.1 , 10.8, 8.1, 7.7, and 8.5 mv splitting the field. The 8.1 and the 7.7 are Struve 697. One of the unsung spectacular sights in the sky. Wow! Position angle approximately 300°, WDS: 286. Strangely enough, this was missed by Burnham, although it gets a brief mention in Webb. WDS data: 7.27 - 8.10mv, B7V, 286° pa, 25.9", 2008. |

| STF 677AB | 5h 24m 44.29s | 63° 23' 11.09" | Little Tycho | C-8 | 2011/Jan/8 20:29:28 | A very close pair, but cleanly split. As per the WDS. WDS data: 7.86 - 8.50mv, G0, 119° pa, 1.1", 2009. |
| STF 709 | 5h 24m 44.9s | -7° 42' 8.89" | Little Tycho | C-8 | 2017/Jan/28 20:54:6 | A dull pair. Orange 4.1mv 29 Ori is in the field. WDS data: 9.88 - 10.26mv, G5, 320.80° pa, 11.230", 2010. |

| STF 708 | 5h 25m 11.27s | 1° 55' 26.1" | B | C-8 | 2008/Feb/14 19:00:00 | I saw position angle approximately 330°, and the separation looked greater than 2". This could have been because the seeing was quite steady. WDS: 322 degrees position angle, 2001. WDS data: 7.74 - 8.90mv, B8V, 322° pa, 2.7", 2001. |

A: 7 Mv, Burnham: 8 Mv, Separation: approximately 15 arc seconds, position angle approximately 15 degrees. (Burnham gives the separation as 31.2" , WDS as 31.1. So much for guessing at the eyepiece. I tend to see things closer than they are). WDS data: 6.65 - 8.33mv, K2III, 350° pa, 31.2", 2007. |

| STF 890 | 6h 21m 40.94s | 36° 6' 47" | Little Tycho | C-8 | 2018/Jan/23 23:25:6 | The 12.3mv secondary is, predictably, hard to see, but it becomes visible in the 9mm. Shorter eyepieces simply enlarge the blurred image due to tonight's windy, Pickering 4 skies. WDS data: 9.71 - 12.35mv, A0, 271.20° pa, 17.820", 2010. |
| STF 898AB | 6h 21m 57.42s | 10° 58' 16.5" | Little Tycho | C-8 | 2013/Mar/4 20:7:52 | A nice pair in a splendid field. This looks like it should be a loose open cluster, but it is not marked as such in the NGC or IC or http://www.univie.ac.at/webda/cocd.html WDS data: 9.00 - 9.61mv, B8, 122° pa, 6.1", 2011. |

My θ is almost 90d from the WDS θ. I saw 52.5° pa, 0.7" sep. This θ was later shown to be spurious, and probably caused by the telescope not being in thermal equilibrium. The star was not split. WDS data: 6.13 - 7.71mv, A3V, 145° pa, 0.7", 2007. |
| STF 897 | 6h 22m 25.94s | 26° 40' 8" | Little Tycho | C-8 | 2011/Dec/30 3:27:42 | A nice, if somewhat faint pair. As per the WDS. WDS data: 8.76 - 8.95mv, A0, 349° pa, 18.3", 2006. |

| STF 900 | 6h 23m 46.09s | 4° 35' 34" | B | C-8 | 2006/Dec/13 03:00:00 | AKA 8 Mon. A nice, wide pair of yellow stars. The double star catalog lists them as an A5 and F5, so perhaps there's a bit of interstellar reddening here. WDS data: 4.44 - 12.7mv, U, 254° pa, 91.8", 2008. |
| STF 882AB | 6h 23m 56.59s | 64° 54' 41" | Little Tycho | C-8 | 2017/Feb/19 21:7:2 | The 10.84mv secondary is almost invisible so near the 8.5mv primary. It was a slight brightening of the halo around the primary. Glimpsed in both the 9 and 6mm. WDS data: 8.5 - 10.84mv, F5, 271.50° pa, 3.823", 2003. |

| STF 887 | 6h 24m 19.47s | 60° 7' 23.6" | Little Tycho | C-8 | 2018/Jan/25 20:58:26 | A very faint pair. Obvious, once seen, but not easily picked out of a low power field. It's not suprising that Struve missed many similar pairs like this one. WDS data: 11.05 - 12.9mv, U, 209.00° pa, 7.930", 2012. |
| STF 903 | 6h 24m 20.57s | -12° 57' 43" | Little Tycho | C-8 | 2017/Feb/19 20:48:1 | An unequal, but not difficult pair owing to the wide separation. WDS data: 6.12 - 10.49mv, B5Ve, 295.50° pa, 23.080", 2010. |

| STF 906AB | 6h 28m 44.86s | 37° 22' 50.59" | Little Tycho | C-8 | 2017/Feb/16 22:43:46 | A very nice, if faint, pair. WDS data: 9.14 - 10.13mv, F5, 336.50° pa, 6.560", 2002. |
| STF 919AB | 6h 28m 49.07s | -7° 1' 59" | B | C-8 | 2007/Mar/08 19:00:00 | Also known as Beta Mon. An exquisite triple star. It looks double at 80X, but triple at 160. Three white beauties. WDS data: 4.62 - 5.00mv, B3VeB3ne, 127° pa, 6.6", 2009. |
| STF 919AB | 6h 28m 49.07s | -7° 1' 59" | B | C-8 | 2006/Oct/06 03:00:00 | A lovely triple. Looks double at 50x, indeed, hard to resolve at that power, plainly triple at 133X WDS data: 4.62 - 5.00mv, B3VeB3ne, 127° pa, 6.6", 2009. |
| STF 919AB | 6h 28m 49.07s | -7° 1' 59" | B | C-8 | 2006/Sep/26 03:30:00 | A beautiful triple of stars. Needs high power. WDS data: 4.62 - 5.00mv, B3VeB3ne, 127° pa, 6.6", 2009. |
| STF 919AC | 6h 28m 49.07s | -7° 1' 59" | Little Tycho | C-8 | 2015/Mar/6 20:10:22 | Seen before, but, as William Herschel said centuries before, one of the finest sights in the sky. WDS data: 4.62 - 5.39mv, B3VeB3e, 125° pa, 9.8", 2012. |

Wikisky: the star identified in the WDS as STF 995 does not appear to be double. The pair I found is 9.7 - 10.4, 24" apart, in 300d pa. The WDS does not identify it, or more probably has it's RA slightly off. My pair is 6h 57m 12.9s, not 6h 56m 20.45s. The decs are virtually the same. WDS data: 8.17 - 8.7mv, G5, 293° pa, 21.7", 2004.2017 May update: The 9.7mv - 10.4mv pair this observation refers to is STF 995. |
