The Triangulum Galaxy, M33

The first clear night with only a few clouds since, well, I can't recall. Even the transparency was good in that I tried 3 min exposures on M33, only to find that the stars appear doubled and M33 smeared on ALL frames. Total pants. See Rev B, the hall of shame. Though with occasional small spikes in RA, the guide curve looked rather good though. Something mechanically must be wrong with the mount or with my biological brain mass. It was my longest ever exposure time and total integration (2.8 hours!).

As usual, no filter, no calibration.

What does an astrophotographer say after such a failure? "Shoot"!
Yep, I must try 3-minute exposures again, before I go nuts. Next is M27. Take cover!

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.
