I read your blog. Glad you had good time in Algonquin and did some observing in spite of bad weather. I noticed your observation of gamma [Andromedae or] Almach. I was observing the same star at CAO using my RC 203mm 'scope and Dietmar's SW ([or] Sky Watcher) 120mm refractor.She shared her observing results from the weekend, plus one from a few years back.
Observing #1She went on to say:
Date: Aug. 30/2006 Place: backyard
Sky cond.: clear, good seeing
Telescope: 102mm SW on EQ4 (no goto)
Star: Gamma AND (Almach) A & B not able to split B & C (sep. 0.4"). At 71.4x stars were touching. At 100x split by hair.
A=yellow, B=bluish green
Observing #2
Date: Aug. 6/2012 Place: CAO (GBO)
Sky cond.: clear, seeing good
Telescope: 203mm RC on EQ5 goto
Star: Gamma AND, A & B only. At 116x fairly close.
A= yellow, B=blue
Observing #3
Date: Sep. 15/2012 Place: CAO (THO)
Sky Cond.: clear, seeing good
Telescope: 120mm SW on EQ5 goto
Star: Gamma AND, A & B only. At 191x fairly close.
A= orange, B=blue
I was able to split Izar in the SW, very clear split no spikes on main star. Also viewed the "double double" in Lyra. Very clear split in SW scope. I decided to keep my RC for now. [And] you were right, primary mirror needs collimation. Thanks for your help.I'm pleased she's sticking with it. I think she'll enjoy the large aperture. It is also satisfying that she's come to trust her eyesight, splitting tight doubles in small apertures.
In addition, it is neat to compare her observations to mine... From Mew Lake Saturday night, Friday night, Thursday night. And then to go back further, like she had, into my notes to Aug 2010 and Sep 2007.

Just the Facts Police here - do you have your mm/yy correct in your last paragraph in reference to Millie's past observing dates?
Um. Yeah? (I did re-word it slightly; maybe just poor composition on my part.)
