Hi all
After an abysmal May as far as weather is concerned I have finally got my filter wheel up and running and as the sky was clear last night (it was up till mn) I thought I'd chance my luck and have a go at the Pelican nebula. After I got everything aligned I was ready to begin just before 12mn but as the camera was taking its dark frame for auto dark subtraction patchy clouds started rolling in from the southwest and this was the pattern for much of the rest of the evening. I decided to stick with it though and managed to shoot 7x10 minute unguided each of Ha, OIII and SII (the last one of the OIII and SII had to be junked because daylight stopped play). The was a period of about an hour when there was no cloud at all but the rest of the time patchy clooud came very close to cygnus and on a few occasions covered where I was imaging (thankfully only for a few seconds each time)
I combined the 6x10 minute SII(red), 7x10 minute Ha (green) and 6x10 minute OIII (blue) Hubble palette style. Onle 3 small iterations of curves were used as well local area contrast in Noels tools. No levels were used. Considering the rush and the threatening cloud I am well chuffed. I have also enclosed a cropped close up of the Pelicans "neck" to show the chimneys a bit better.
Thanks for looking
Clear skies
