hi friends,
on satrurday night another storm was blowing across the country, clearing up the athmosphere and causing a terrific transparency.
seeing of course was very bad then, the stars were growing to kind of snowballs and this gave me a hard time to bring them back to "normal size"...
autoguiding was impossible - I had never encountered that before.
the guidestar was bouncing around on the chip, leaving weird patterns and the focus was very hard to find.
nevertheless I wanted to image a bit and so I used the 4" Tmb and captured M 101 for some 2 hours.
data on the image:
M101
4" TMB Apo f/6,2
SXV M25C
2 hours (4min and 8 min subframes - unguided)
AA4, PS CS2, PixIS LE
seeing 1-2/10
transparency 8-9/10 !!!
