Description

Breaking in a new camera--the ASI294MM Pro. It's large pixel size and really deep well are a delight to work with. Funny but encouraging story: first light for the camera was the Lobster Claw nebula in narrowband. In pre-process, the Sii subframes were WAY over-exposed, and so were the flats I took for that filter. But same 240 sec exposure...what the?? Then I realized I had a broadband red filter in the Sii slot. However, the dynamic range was large enough that the red subs were actually usable; I just linear fit them to the rest. Think I'm going to like this camera.

Most of the NGC 218 here was shot near full moon but only the Oiii showed minor gradient. The palette is a modified SHO.
