Description

This is 10.5 hours of narrowband data and 1.5 hours of RGB processed as HOS.

About 5 or 6 stars come from the RGB data - it doesn’t matter much in this image. My experience guiding the CEM60ec is growing as I make new and better mistakes. It is very sensitive to being out of balance, and it doesn’t seem to like being weighted to the east very much. The axis clutches need to be adjusted carefully - in the middle part of their range - or you end up with that old sinusoidal pattern of guiding.
