Yet another good data night

[Tom Droege <droege@wwa.com>]

Another 2 CD ROMs worth of data last night to add to my stack.  About 12 so
far.  I am beginning to see a problem.  My guess is that we will have a 5
mag range between noise and saturation.  If I am correct (from star counts)
that we can measure mag 15, then we saturate at 10.   This means that we
will need a catalog of mag 11 or so stars for calibration.  Is this available?

I think I will follow Arne's suggestion from now on and take an exposure
sequence - say 20 and 200 seconds while following the field.  So I will
start taking the sequence 20, 200 back up, 20, 200, etc. ...

What do you all think?

I added an 11 GB disk yesterday to give me more space to take data.  The
usual things happened, I even tried to reload Windows which did not work
either.  Eventually I got it to work by uninstalling the CD ROM writer.
Now I can try to install that again today.   Sigh!
