CRESCENT NGC6888 over a few nights

[andyo]

Hi all been processing this which I took over 4 nights.I didnt intend to do that which is why the exposure times are all different.

I took;

9x270 sec lights,20xdarks,

24x300 sec lights,30xdarks(over two nights)

20x150 secs lights,20xdarks

20x flats and 20x bias

Stacked in DSS and processed in PhotoshopCS6

It has been cropped due to coma.

I found this difficult to process I am not sure about the raw settings in DSS for example what do you put in the colour adjustment values for brightness,red and blue I just left them as they are.I mainly folllowed the recommended parameters.Any comments welcome
