Description

Acquired this data as part of a process to full understand calibration of the Aluma AC4040 in different acquisition modes. I wanted a dark nebula to see if I could develop some dust in the face of some chip level pattern noise. I had to cut the full field image down to about 1/4 frame to get some usable data from this run. After this run I determined that the on camera stacking at low cooler temperature was somehow locking in pattern noise that the darks were not able to correct. I was able to change to a separate mode and turn the cooler up and eliminate most of this in subsequent images. This was the usable part of the image after I cropped out the chip patterns.I feel it is OK given the calibration issues I could not eliminate in processing.
