M81/M82 LRGB test run

Happy days are here again! :-)

At long last I think I have a handle on the technical glitches that have been making my imaging sessions miserable and frustrating over the past number of months. It's been quite some time that I've been able to leave the scope unattended with a decent expectation that it will run through without a disconnection issue (and it wasn't anything to do with QHY drivers!).

I was a bit surprised that I haven't done M81/M82 since I got the CCD, but seeing as as they are overhead at the moment it seemed as good a time as any. Broadband flats aren't the best as the flat-field generator isn't very uniform at its lowest brightness but the mechanical shutter on the QHY9 needs longer exposures - not an ideal combination.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
