hey folks
tonight was the night! I went to andromeda!!!!!!!! the closest galaxy to us! hopefully I will conquer it soon..its only a matter of dark skies and I will take it down completely
I tried 4 times...here is the close to good I can do..but im not quitting im going to retry the 60 frames and hopefully today.. I will another 60 to get the spiral arms!..but I just don't know how to solve the gradient in the image...
Exposure details of M31:
60 frames
ISO 400
2 min per frame
shot started at approximate 45'degrees...I don't know when it ended cause I slept 
20 flats
20 darks(taken from NGC 6888 of last week due to certain laziness)
First shot:
Deepsky stacker..with kappa sigma mean 4 sigma 1 iterations
sent to photoshop and stretched 3 times....finally using Noel's carboni's tools to get the spiral nearly visible

Very nicely framed.
Have you tried setting the black point to loose that orange sky? The other thing to be careful of is that it looks stretched way too far for the data you have - i.e. that banding thats showing up and the noise.
There is a natural temptation to dig out those faint spiral arms - but you should resist and go for longer exposures to get better data

Good shot Max. The gradient looks like a street light is shining across your glass. Do you have a dew shield on? Next set-up, wave your hand in front of the glass and see if you create a shadow from a nearby light source...but the test won't work well when the moon is bright, like now.

thanks folks
I did use the black point..but it is difficult to loose the orange in the upper right..its more concentrated to the right than to the left... I think I will wait 17 more days to go to a dark site... and take 10 shots worth of 600 seconds!!!!! and im done!
yeah nick there are lots of street lights.....:(( starting from the 6 street lights shining white ! + the red killers who just can't let me take more photons !:((...no dew shield here..

Nice attemp 
I'd say thats a LP problem as wellas low SNR. I tried some removal using PixInsight LE, seems a little better, but more subs with either a good LP filter or darker skies will help too.
