Need advise on how to align stars for Narrow Band processing

by Steve Coates

Dec 3, 2011

Ok here goes...
I've trying like heck to learn how to process NB images. I've got a decent base but the thing I am really struggling with is how to align the stars to make an HaR image and then HaRGB. When I go to stack the Red channel to Ha (or HaR to RGB) in Photoshop I can get about 3/4 of the stars to line but I always get that last 1/3 to 1/4 that end up looking ghetto. I use all the settings in the Move Tool but I can never get a full alignment of the stars. I hope someone has some advise on how to get past this.
Thanks in advance,
Steve

    Do you align the two images in DSS? And/or tried auto align in PS? Marc

      So, what I do is register/align/whatever-you-want-to-call-it all channels together after calibration but before stacking. Then just stack each channel like you normally would and integrate the channels as normal. I assume you're using Ha for luminance?
