05/09/12: Imaging session

September 06, 2012  •  Leave a Comment

This evening was the first real imaging session as the nights are starting to draw in again now. I decided to have a go at the North American Nebula NGC 7000 in the constellation Cygnus. This is an extremely large emission nebula and a good target for hydrogen alpha imaging. The weather was good and I shot two hours worth of subframes before calling it a night when the target began approaching the meridian.

I have processed the image with a focus on sharpening the 'wall' to bring out detail within the nebulosity. This involved using the unsharp masking function within Photoshop. I'm pleased with the result and hopefully aim to add some OIII data in order to generate a bi-colour image.
