Second test image of season. Not so good this time, Dec guiding very bad and poor polar alignment not helping much. Not dark. Collimation flopped as well when I looked the next morning. Still, focus is looking nice, and I'm suprised to see IC1296 showing so much structure given the bright skies. Click on image for full size.

Captured in Artemis Capture, calibrated in maxim, fiddled in photoshop.

This image was autoguided using my 400mm focal length refractor and my black and white SC1 webcam.
