I had a chance to go out for a quick session last Saturday night and then again last night for a little longer session. Last night was really fun as the seeing was better than normal and I was able to get split as tight as 0.9" doubles and probably could have gone down to 0.7" or 0.8" on near equal, not too bright doubles. I wish I would have been able to stay out longer, but I was getting tired, my finderscope and Telrad were fogged up, and my shoulder muscle on my right side was tightening up a bit. Oh well, it was a blast while I was out there!
As I was looking up a couple of the observer names from the reports below I noticed that there is a lot more data on Stelledoppie than I realized before. I just now noticed the tabs for Notes/Reports/Measures/Images/Neighborhoods/Complete. Very informative!
I think I have two short term projects that I will do.
1. I need to build some dew straps/shields and a dew heater controller. I have plenty of diy electronics experience and was a professional programmer and architect for 15 years.
2. I need to redo my base where the xt10i tube connects. Since I'm not using the controller at all, I want to move to more traditional altitude bearings (my current setup is pretty shaky and I have to tighten the bolts too much at times). I already have plenty of leftover Baltic birch, teflon, and most of a 4'x8' sheet of laminate material, but no router. Or...maybe I'll contact Dennis at Dobstuff and see if he can make just the bearings and vertical pieces of the mount...my groundboard works great.

Short session, but wanted to get out there for at least a little while.
STT485 (V638 Cassiopeiae) - 6.53/10.14, 18.8" @ 48, Cassiopeia - Easy split with the 30. AC is a physical double. Bright star with two dim companions.
STT480 - 7.57/8.64, 30.7" @ 116, Cepheus - Bright wide physical double. A couple other bright stars in the fov of the 12.
BU436 (Burnham 436) - 7.42/12.00, 19.8" @ 327, Cepheus - Split with the 12. Primary is bright white and the secondary is pretty dim at mag 12.
STF2872 - 7.34/8.00, 0.8" @ 296.3, Cepheus - A physical triple! The A, BC is a bright wide double. I can see elongation of the BC, but cannot split it. Probably a little too bright for the separation. The D star is readily seen though. Used both the 12 and the 4.7.
BU108 (Burnham 108) - 7.73/10.60, 4.6" @ 6.0, Cassiopeia - Can see the A, B, C, and F stars. According to SD, the AB pair is physical.
MRI31 (Martin 31) - 8.06/9.01, 115.4" @ 9.0, Cassiopeia - Another bright, wide, physical double.
HJ1088 (Herschel 1088) - 6.36/9.79, 19.5" @ 168, Cassiopeia - This one was pretty easy to split with just the 30. Prior to this I had been unable to split a few pairs of close doubles, so I needed one that I could. According to SD, this is a physical triple system. Really cool!

Seeing was really great last night compared to more recent sessions. Had a couple of my best splits this year. My best split is 0.8" and last night I split a fairly bright pair at 0.9" separation and a couple other pairs near 1" separation including a pair that had a couple magnitude difference.
STT423 - 7.15/9.64, 2.7" @ 76, Cygnus - I tried viewing this double last weekend, but wasn't successful. Seeing is a bit better tonight and I can make the split with the 4.7. Plenty of separation, but still a little tough due to the mag difference.
STT414 - 7.42/8.93, 9.9" @ 94, Cygnus - I was able to make the split with the 30 since the pair is wide enough. Watching it drift, it appears as if the secondary is chasing the primary as they drift through the fov... The pair has a pa of 94.
STU13 (Sturdy 13) - 7.59/10.13, 27.1" @ 196, Cygnus - Another pair that was viewed with just the 30. Forms almost a trapezoid with 3 other nearby stars. This pair is physical per SD.
STT410 (V2130 Cygni) - 6.11/6.83, 0.9" @ 3.4, Cygnus - I made the split! Not 100% of the time, but about 50%. Holy!! Two stars marching side by side across the fov of the 4.7. Very happy. Saw the C and D stars as well. The AB pair is physical and SD has orbital data. Period is 14.08c. I watched this pair for a good 10 minutes.
STF2731 - 7.71/9.59, 4.1" @ 86, Cygnus - Easy split with the 12!
STF2746 - 7.63/8.71, 1.2" @ 323, Cygnus - Another tight pair that I was able to split tonight with the 4.7.
STF2758 (61 Cygni) - 6.05/5.24, 31.8" @ 152.7, Cygnus - I've viewed this pair before, but I didn't know about SD at the time. This pair has orbital data and I believe I've heard there are confirmed planets revolving around them. Very beautiful orange stars. I wonder if there is life there and if there is, what the skies must look like with 2 suns? Note: No confirmed planets, but I think my confusion is that there used to be believed that there were planets revolving around one of the stars.
SEI1445 (Scheiner 1445) - 7.34/11.90, 28.0" @ 23, Cygnus - Wide separation, but pretty dim secondary which was tough to see with the 4.7, but I did see it.
STT434 - 6.67/9.93, 24.5" @ 123, Cygnus - Nice wide double that was easy to split with the 30. This one is a physical double.
STT432 - 7.15/8.05, 1.4" @ 115, Cygnus - Another right pair that was fairly easy to split tonight with the 4.7.
STF2820 - 7.46/10.56, 16.0" @ 230, Cygnus - The secondary was a little tough to pick up with the 12, but it was seen. This is another physical double.
BU694 (Burnham 694, V1942 Cygni) - 5.59/7.76, 1.0" @ 6.0, Cygnus - An uncertain double, but one I made sure to check out with tonight's better than average seeing. I was able to split it wth the 4.7. This was probably the toughest split so far tonight.
STF2902 - 7.46/8.22, 6.5" @ 89, Lacerta - Yellow main star. Near equal double. This was an easy split tonight with the 30.
STF2918 - 7.67/9.43, 1.7" @ 238, Lacerta - Took a bit to see the secondary with the 4.7.
STF2917 - 8.40/8.56, 4.8" @ 70, Lacerta - Near equal magnitude physical double. I could split with the 30, but the 12 made it really easy. Both stars are yellow to me.
ES1028 (Espin 1028) - 7.57/10.57, 6.0" @ 243, Lacerta - Another physical double where the secondary was not real easy to see due the moon. Used the 4.7 to split.
HJ1791 (Herschel 1791) - 7.63/9.68, 17.1" @ 59, Lacerta - Physical double, yellow main star, faint secondary with the 30.
STF2953 (V453 Cephei) - 7.55/9.52, 8.5" @ 137, Cepheus - Split with the 12. Uncertain double. Fairly large mag difference, but also fairly wide separation.
STF2950 - 5.82/7.08, 1.1" @ 271.8, Cepheus - Yellow, almost orange main. Can only split the AB pair about 30% of the time with the 4.7. I can also make out the C component. According to SD, this is a physical triple system! AB orbital period is 804y. Very nice!
STF2977 - 6.76/10.33, 1.8" @ 355, Cepheus - A physical double. A tough split even with good seeing and magnification due to closeness and mag difference. Used the 4.7.
It's funny, as I write up the observation logs I want to get right back out there right this minute.
Until next time...clear skies!
