Gday
I have taken a few Ha images but with the recent arrival of the OIII filter and the imminent arrival of the SII I have decided to have a go at NB composite. Everything Ive read says somehting like "
take your NB images and process them as normal prior to combining" . This is a 4 hr (16 x 15 min subs) image - a lot I know but it was last weekend, the moon was bright and I only had a Ha filter - so I thought I may as well keep capturing data - calibrated just with darks and flats, and stacked then auto levelled and first light sharpen filter in PS (the spikes are just to see if I could do them - they'll go) - no curves - no gamma corrections etc etc.
To me this looks like what I would think a Ha image of this object should look like. Seperate to a stand alone Ha image, do any of the nb composite gurus out there have any tips regarding processing prior to false colour combination.
PS - I wasnt allowed to go to the observatory and play this weekend to capture OIII due to some Sunday function with my wife and the kids (Youre not my mother was my arguement - that went down like a lead balloon)
I ducked really quick. I didnt push it because I really want that Meade 10" ACF in a cuple of weeks.
Joking because I think I would rather see my grandkids than stare at PHD for hours. Also any of you Qld guys that know us should know that I would be singing soprano if I tried to say that seriously.
Anyway any info re use of this image (and / or adjustments required) for use in a NB composite would be rgeatly appreciated. The learning curve gets steeper.

Obviously the jpg compression looks very little like the fits but hopefully you get the gist of my question.
Thanks
