Sure felt like a breakthrough moment. Erik, I probably have overdone the color here. I definitely pushed everything a bit too far and am not satisfied with the result. The raw data looks good, just fussing with the processing. -------------------- Bryan Sayler Celestron C9.25; Orion ED80 HEQ-5; Orion ST-80 w/starshoot Nikon D80; Canon 40D Hap Griffin Mod Empty Wallet Post Extras:       Tonk Post Laureate Reged: 08/19/04 Posts: 4497 Loc: Leeds, UK, 54N Re: My First Horsehead [Re: bryansay]       #3400508 - 10/20/09 04:07 PM Edit   Reply   Quote Quick Reply   Good image but I would say its very heavily clipped at the black end of the histrogram - which should be avoided -------------------- Televue 85, GM-8/Gemini, Canon 40D (unmodded), Canon 450D (modded w/Astronomiks clip-ins - UV/IR, OWB) Coronado SM60/BF10, Baader Herschel Wedge Leeds Sky Clock Ripon Sky Clock Post Extras:       xatamec member Reged: 09/12/09 Posts: 81 Loc: Catalonia, Spain Re: My First Horsehead [Re: Tonk]       #3400525 - 10/20/09 04:17 PM Edit   Reply   Quote Quick Reply   Hi briansay, I agree with Tonk, the image is very clipped at the low lights. I suppose you did it to darken the background and to get rid of the noise, but it makes the image to look a bit "artificial". I would do a less agressive histogram stretch and would not clip the histogram at all. Also, increasing the color saturation very much adds much noise in the crominance. It should be done moderately. It is a very good shot anyway Sergi -------------------- My telescopes: WO Megrez 88FD APO and SW 200/1000 My mount: SW EQ6 My cameras: Cooled Canon 350D, QHY5 ...and very little time to play with these toys!

I agree with your observations. You are very accurate on both my attempt to darken and enhance color. I am still a little "coarse" in my photoshop skills and have yet to develop the patience that is evident in your work. I will give it another shot this weekend and will try to use a more delicate touch. :-) -------------------- Bryan Sayler Celestron C9.25; Orion ED80 HEQ-5; Orion ST-80 w/starshoot Nikon D80; Canon 40D Hap Griffin Mod Empty Wallet Post Extras:       bryansay super member Reged: 02/25/09 Posts: 178 Loc: Georgetown, TX Re: My First Horsehead - Reprocessed [Re: bryansay]       #3413172 - 10/26/09 11:17 PM Attachment (26 downloads) Edit   Reply   Quote Quick Reply   Hi all. I took the feedback received here and tried to reprocess this image to look more natural. Please let me know what you think of this effort.
