Re: [APML] Some M31 Help

["Volker Wendel" <volker@spiegelteam.de>]

Hi Rob,

I like the latest image more than your older one because it has more neutral
blue.

There is one thing I noticed sometimes before in your images: the upper left
shows most of the time a magenta colored background, the lower right a more
green background. I´m sure this has something to do with your flatfielding
or the brightness gradient of the night skies at your observatory side. This
results in your latest M31 version in magenta colored faint stars at the
upper left and green stars at the lower right.

If you should solve this problem, you could increase a 99,99% perfect image
to 100% <G>!
