DS images from 2004-07
Older DS images from 2005-7
M31 is beautiful and very problematic target.
Large angular size, low surfage brightness and large dynamic range
combined to heavily light polluted location, is not a good combination.
Anyhow, here is the result this time.
I really need a darker location.
SW80ED and QHY8
guiding LX200+QHY5+PHD-guiding
4h total exposure time.
M33 is adifficult target from light polluted evnironment.I use four hours of exposures for this. Noise porblem and very low S/N are coused by LP. SW80ED QHY8, guided with LX200+QHY5+PHD-guiding
I had some extra time, so i went trough my archives.
Here it is famous 17P/Holmes.
At the time it was easy to spot with naked eye.
Two hours of exposures with QHY8 and SW80ED.
M13
My very first DS image ever.

My very first DS image ever.I was very proud, that I was able to see spiral arms
in my picture! Image is taken in Alt/Az mode acd there was
only 12x30s subs, no guiding.
NGC3718, thanks for solving it Philipp
