NGC7380-SH2-242
I posted this originally back in October 2007. It was somewhat noisy as
my old monitor, even then was failing to show me this. It kept calibrating just fine yet not showing noise. Still don't understand that. Anyway I posted this in response to Richard Crisp's image but then noticed it had gone flat compared to the original. So I punched it up a bit. Until I get more data this will have to do. Lum = 3x30' H alpha while the color is pure RGB 3x10' all binned 2x2. When I tried adding some Ha to the red and blue as I usually do it altered it so much I didn't like the result so while this makes for noisier color I still like it better for some reason. Rick -- Correct domain name is arvig and it is net not com. Prefix is correct. Third character is a zero rather than a capital "Oh". |

Very good image Rick. What strikes me most about it is the grey area in the
central part. It looks mostly colourless in Richard's image too, so it must be real. Makes me wonder what causes this "pale" appearance. Stefan "Rick Johnson" schrieb im Newsbeitrag ster.com...

It shows in my H alpha image but is very strong in the blue frame,
weaker in green. I think it both a reflection and emission area but the blue of the reflection about cancels the pink of H alpha and you get this gray color. Odd though how sharp the divide line is. It doesn't fade to pink but just suddenly turn to color. I didn't process this area separately in any way so think it real. Rick Stefan Lilge wrote: Very good image Rick.
