It has been a long rainy winter here, very few clear skies! I originally was not going to bother with processing this data. But, what the heck. I wanted to recapture all the lum data and some Ha in addition. However, that never came to fruition due to the record amount of rain we have had.

It turns out that my luminance data has a very bad fixed pattern noise. This seems to be an issue that can occur with the ASI 1600MM when imaging at 0 Gain. If you take a look at full resolution you can see the horizontal banding, despite the heavy-handed noise reduction :( Oh, well there is always next year :-) and maybe clearer skies!
