One of my DSO Astrophotography goals was to take photos of more distant galaxies than the Andromeda Galaxy. Learning how to use the ASIAIR Plus, re-learn stacking techniques, and learning how to post process has been a steep learning curve. I got a Starwatcher Az-GTI mount for a portable mount that I can take to see the 2024 Eclipse. I wanted to use it as a test for astrophotography. While guiding was very very successful (1 to 1.5" arc second guiding even with a setup pushing the weight limits), one of the legs was not fully tightened and my full rig fell to the ground at the end of the night. I broke my full-spectrum modified Sony A6000 after only owning it for 1 month and lost the flats that I had for that night. Fortunately I had some darks with the same exposure which I could use, and I processed this image of the M81 Galaxy Group. I had to do some serious dust removal due to the lack of flats. You can see Bode's Galaxy and the Cigar Galaxy plus two more galaxies in frame. On the brightside, my ASIAIR, guiding setup, mount and Skywatcher ED72 were not damaged so hopefully I will have a replacement soon.

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.
