Description

The first stage of imaging NGC 6888. This is just the Ha data, with basic dark, flat, flat dark calibration and a stack of 52 x 20 minute frames. Very basic stretch to see whats there.

Imaged over 5 nights. I also tested continuous temperature compensation with the Optec Gemini focuser. This only required an initial auto focus followed by up to 5 hours automatic temperature compensation.

The second stage is getting RGB data. I will be using the Ha data as a proxy luminance channel
