M31 the Andromeda Galaxy bathed in ionised Hydrogen. Imaged with Pier14 Exposure times were 140 x 240s frames in H-a with LRGB 100 x 180s in each channel a total of nearly 31hours. The faint H-alpha in the background was very difficult for me to pull out probably making this my most challenging process to date.
Thanks for looking

lovely result. The green filter is actually 100seconds instead of 180s and i had trouble in WBPP with it so submitted a job with the 180s exposure. BTW your astropix.co.uk site says account unavailable.....

Hi Vikas,
Did you try using the 100 seconds subs in the end? WBPP will warn if there is no matching master dark, but it will run by using a scaled dark to match the exposure. Best to supply a closely matching one like the 120 seconds master. So did you go ahead and manage to process M31? From what I have seen others have posted the results should still be excellent.
Cheers,
Ray

Hi Peter,
Amazing job you've done on that to bring out what is so very faint. Definitely should be shared with a much wider audience, so fingers crossed that it will be quite soon. All that hydrogen, perhaps we should hold off buying electric cars for now.
Have a great time out there in Spain.

Ray
