This is the first time I got more than an hour of anything so naturally I thought it would be great.
I had of course forgotten that I am cr#p at processing galaxies.
Its a bigger image (cropped) so I've left it at www.dancalleja.com. Very unhappy. I've also left the uncropped version
It has a cast that I cant get rid of but more irritating is a background of 'sand' that I can't seem to process out. I've seen this before in my galaxy imaging and cant seem to overcome it. My workflow is:
CCSDtack
Convert to colour; register and normalise; remove hot pixels; combine median; convert to tiff; process in CS3.
CS3
Three curve stretches; colour range and background gaussian blur; some noise removal; some saturation tweaking.
I'd appreciate any tips from the galaxy imaging gods! |
Hey don't beat up on yourself so much everyone has to start somewhere every one you do will be better and you have to have something to look back at and say look how far I have come
