NGC 6888 - a "first light" target...

[Hallingskies]

I chose the Crescent Nebula (NGC 6888) in Cygnus to try out my new imaging set-up last Sunday evening.  A high haze and horrendous dew stopped me from gathering the OIII data I wanted, so the images below are the result of 20 x 300s using a Baader 7mm H-alpha filter, with 20 darks and flats.  The first image is the full frame output from my shiny new Atik 460EX, with the second being a crop of the Crescent itself.

The full frame image does show up the slightly eggy stars in the corners, meaning I probably need to tune up the camera back-spacing a bit. I am very pleased with the sensitivity and noise characteristics of the 460EX, even though the warm weather restricted me to a camera cooling set-point of only -5 degrees.

Any comments or suggestions welcome...

Nice first light. Should be some lovely images coming from that setup.

Very promising indeed!

Thanks folks. Just need the clouds and software gremlins to stay away...
