6 january 2020

To my disappointment seeing was not very good last night. Even with the 8" mask the images would not support anything above 205x. I avoided roof tops and observed on either side of the waxing moon (which was throwing off a strong glow due to also poor transparency), picking easier targets to observe. Still satisfying and productive over two hours. I have to add, I really love the winter Milky Way: plenty of fine stars in the fields I was observing in, and in the finder, to keep me enchanted. It was pretty cold out, but less dewy than the night before. I happened to see a mouse running along the top of the fence at one point, likely headed toward the bird feeder. Fortunately none have made it into the shed, yet. Weather will be mixed the rest of this week, so I'm not sure when I'll get out again.


HLD 7 AB; 8" 533x; Yellow A and bluish b, just split the faint B, in a swimming mess due to poor seeing.
02h 25m 25.96s +58° 12' 09.3" P.A. 182 sep 1.7 mag 7.98,9.86 Sp A3V dist. 150.38 pc (490.54 l.y.)

STF 158 AB; 8" 205x: Nice split, pretty wide considering low magnification. Orange-yellow stars about half delta mag.
01h 46m 44.07s +33° 09' 45.5" P.A. 272 sep 2.2 mag 8.96,9.40 Sp F8 dist. 104.06 pc (339.44 l.y.)

BU 1016 AB; 8" 205x: Suspect elongation, seeing not supporting higher magnification
01h 49m 46.70s +33° 03' 57.9" P.A. 43 sep 0.7 mag 9.94,10.13 Sp A0

HJ 645 AB; 8" 205x: The A star is a yellow-orange and B is wide and faint but a nice little point, seen with direct vision but just at the edge of where averted would be needed.
01h 52m 36.06s +31° 27' 22.8" P.A. 106 sep 7.7 mag 8.90,10.70 Sp K0

A 1920 AB, 8" 205x: ! Nice clean split, very pretty white stars, seems a bit more than half delta mag.
01h 57m 52.62s +33° 10' 19.6" P.A. 236 sep 1.8 mag 9.47,10.05 Sp K0

STF 201 AB; 8" 205x: ! Epsilon Tri. Very nice! Bright A star is a white blaze, and outside of its glow is very small point of the B star, very fine. Very nice indeed
02h 02m 57.97s +33° 17' 02.9" P.A. 119 sep 4.2 mag 5.52,11.40 Sp A2V dist. 120.05 pc (391.6 l.y.)

COU 1068 AB; 20" 333x: Seeing isn't what it needs to be. Suspected elongation at 205x, 333x elongated it more but did not split, the star images are too hairy.

STF 227 AB; 8" 205x: 6 Tri. Yellow A, white b, pretty. Wide, about two delta mag.

J 2016 AB; 8" 205x: Xi Ori. There are a few faint stars around the bright white A star, but certainly the closest is the B. Surprised I can see it given A's glare. [5 star system all faint & wide]
