Crescent Nebula NGC6888

Recommended Posts

A wide-ish-field view of the Crescent nebula in Cygnus from last night, though I think it could stand another hour or two of subs to help clean it up. Don't go hunting for the bubble, the image scale is a bit to wide and the resolution a bit to low to pick it up. I might have to have another go at both objects once I have the reflector mounted again.

This is a region where a modified camera would do wonders, I really should get on with doing mine.

Cygnus in general is a brilliant target for a Ha Hoover .. pop that filter out go on you know you want to... you wont regret it ;)

at first I thought it was done with a mono ccd using something like the HST pallete, I like the colours. It's amazing for an unmodified 1000d. I know the mod lets in much more Ha, but for me it seems to make things very red. Perhaps it's just my lack of processing skills, but it would be interesting to see if a mod'd one could turn out the same mix of colours.
