There are two other pairs very close to this one, but they are about 2mv fainter and not in the WDS. Aladin, UCAC4: Given the wide difference in proper motions, ES 2583 does not appear to be physical. The lower pair does, although the proper motions are small. The stars are UCAC4 716-1164495, 10.6mv and 716-011097 11.1mv. Many of the fainter stars in this field have similar small proper motions, suggesting an unmarked cluster.

However, an ~12.5mv star was seen at 230°, 15" from the primary. Aladin/DSS/UCAC4: The AC pair is shown. C is 12.5mv and my estimate of θ was a bit off, as the hazy moonwashed sky made a 12.5mv star almost invisible. WDS data: 9.7 - 10.4mv, U, 173.90° pa, 3.000", 2011. |

The field is lovely, and looks like a large cluster, but it's not in the NGC or IC. Aladin, UCAC4: The proper motions of the brighter stars do not seem to be correlated. WDS data: 8.31 - 9.97mv, A0, 242° pa, 35.2", 2005. |

An amorphus blob in the 4, and only occasionally glimpsed in the 6mm. The seeing was deteiorating as I observed A 2224. This greatly increased the difficulty of splitting the pair. WDS data: 8.25 - 9.63mv, K0, 332° pa, 0.9", 2008. |

| STF 878AB | 6h 21m 28.12s | 62° 24' 5.39" | Little Tycho | C-8 | 2018/Jan/25 20:48:33 | A wide, dull pair. common proper motion? Aladin/UCAC5. The proper motions are different. Probably not a physical pair. WDS data: 7.92 - 11.22mv, K5, 341.60° pa, 34.800", 2003. |
| 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 90° 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. |

| OL 67 | 6h 23m 0.43s | 22° 13' 12.8" | Little Tycho | C-8 | 2014/Feb/19 19:44:30 | The primary was found but the secondary was too faint to see. Aladin: the 12.0mv secondary is there, but was hidden in the glare of the 10.9mv primary. WDS data: 8.8 - 10.mv, U, 40° pa, 5.2", 2008. |

| 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. |
| S 518 | 6h 24m 21.15s | -16° 13' 28.39" | B | C-8 | 2009/Jan/28 04:50:00 | Lackluster, appears as advertised in the WDS. WDS data: 6.98 - 8.40mv, A6V, 88° pa, 16.5", 2010. |

| BAZ 9001 | 6h 25m 35.68s | 21° 32' 50.5" | Little Tycho | C-8 | 2014/Feb/19 20:37:20 | An OK pair in a lovely field. WDS magnitudes accurate. WDS data: 9.3 - 9.3mv, A0+A0, 238° pa, 16.2", 2000. There is a pair 16' SSW of 10mv stars not in the WDS. Aladin: UCAC4 proper motions are not similar for this pair. |

Aladin/DSS: A weird pair of diffraction spikes from the primary. This could be a close pair. Need to look at them through a bigger telescope and/or better skies.

The 12.5mv star (UCAC4 504-4253962) has only a single entry in the UCAC4, but it's image is slightly elongated. The 2MASS catalog does show two stars. A possible binary? WDS data: 8.94 - 9.27mv, A3, 208° pa, 1.4", 2011. |
| STF 2406 | 18h 49m 55.77s | 26° 25' 30.59" | Little Tycho | C-8 | 2018/Jun/26 1:45:26 | The faint companion was washed out by the bright primary. Only glimpsed in the 2.8mm. WDS data: 7.12 - 11.21mv, A3V, 4.50° pa, 4.830", 2004. |
| STF 2406 | 18h 49m 55.77s | 26° 25' 30.59" | Little Tycho | C-8 | 2018/Jun/26 1:47:29 | There is an 8 star cluster WNW of this. Aladin/Gaia DR2: Parallaxes and proper motions indicate that this is a chance grouping of stars. |
| HJ 1352 | 18h 50m 3.28s | 29° 48' 55" | Little Tycho | C-8 | 2013/Sep/17 20:20:22 | A lackluster, wide pair. The companion is very difficult to see in tonight's almost-full-moon skies. It looks more like 11.5mv, not 10.0. Invisible in the 24 and 12.5, I only saw it in the 6 and 9. WDS data: 7.8 - 10.0mv, A0III, 249° pa, 13.7", 2006. |

The secondary of ES 2028AB is an 11.2mv star much closer to the 4.3mv orange star. The proper motions of these two bright stars, A: -7.4, 4.1; Burnham: 0.8, -3.1, show that they are not in common proper montion. WDS data: 4.30 - 11.2mv, M4II, 351° pa, 86.6", 2009. |

The primary occasionally showed hints of elongation, but I think that this was just the seeing. WDS comments indicate that the secondary is a 0.7" neglected pair. The magnitude of the C component was not given. It might well have closed up. WDS data: 8.06 - 9.36mv, G0, 172° pa, 3.5", 2011. |

It's obviously not a single star in the 9mm and shorter, but it's best in the 6mm, and then not easy, as it's fairly faint. WDS data: 9.30 - 9.59mv, U, 28° pa, 0.8", 2009. |
