Two nights ago, (7/16), the wind had cleared the forest fire smoke out enough that I thought it worthwhile to roll out the APM 150 for a look at the sky. The +/- 1/4 waxing Moon was still well up, so while dusk was gathering, I took a good look at it with the 12.5 mm Docter eyepiece pair, to revisit the Petavius Crater. I think I was able to identify the crater, but the thin black line visible during earlier visits was not visible. Probably the Moon was two or three days too far past the "new moon" for that shadow or whatever to be visible.
By now Vega was visible, so without setting up the Nexus DSC, I aimed at Vega and began an easy search for the nearby double- double. Soon it was centered in the 1.22 degree FOV, but at 67X was unable to split either one of the doubles. This called for more magnification, so in went the Morpheus 6.5s for 129X. With these, I could split the southern double, and the other was well elongated, but couldn't get a clean split. Since I had not used the ES 4.7mm 82 degree pair for a long time, decided to try them. After a bit of tinkering and turning of eyepieces to get both barrels looking at the same spot, both doubles were split, the southern one quite cleanly, with a solid black bar between the two components, oriented perpendicular to the elongation. The northern double was still quite sketchy, but during moments of best seeing, I could definitely split that one also. It was not nearly as clean, however, as the southern one, but the tiny black separating bar was definitely perpendicular to the elongation.
Having a desire to compare the 4.7 ES with the Morpheus 4.5 pairs, I fetched the latter from their case in the shop and took a look. There was really very little difference between the two, as far as resolving the splits. The Morpheus were slightly better as would be expected per the slightly greater magnification, (179X vs 187X). The ES pair had noticeably less light scatter and spiking, but the Morpheus more than made up for this in the greater comfort and better alignment / image merging. The ES eyepieces have always been problematic in both of my APM BT's to achieve perfect alignment, and thus merging, due to the shape and size of the "safety cuts" in the eyepiece barrels. They just don't seat into the adapters or focusers consistently.
Following that exercise, I did some sightseeing around the area of Vega, and came across two more double stars. Due to not having the Nexus operating, I'm not real sure of their identity, but going from memory and consulting Sky Safari 6 Pro, I think they were BD +37 3199, a mag 11 star with a 11.3 secondary component, separated by 1.7", and HD 172649, a mag 7.1 primary with a dimmer secondary, separated by 2.1".
HD 172649 was a much easier split even though the separation is listed as not being that much different. Perhaps it was due to the greater brightness, or I could also have mis-identified one or both pairs. BD +37 3199 was very dim, although I could see that the secondary was definitely slightly dimmer, and very close to the primary.
In retrospect, I believe I mis-identified both of these doubles. They were easier to split than the Double-Double, but should have been at least as difficult if the separations given in Sky Safari are accurate. Will have to find them again, using the Nexus for a more positive identification.
