M81 Bode's galaxy

First attempt at a longer integration time from 2 imaging sessions after removing some backlash on the mount by following 'Cuiv the lazy geek's' method. Also did a fresh PHD2 calibration and disabled permanent periodic error correction (PPEC) in EQMod as I suspect I had not recorded it properly the first time. The guiding on the first night hovered around Total 1.1'' and the second night averaging 0.8'' but as low as 0.6'' using PHD2 all star guiding. The biggest improvement seemed to come from applying a bit more East heavy bias on the mount and remembering to move the counterweights to a predetermined mark during a 5 minute pause in the N.I.N.A auto meridian flip. Processed using a trial version of Astro Pixel Processor. I think I need to work on acquisition and processing to help reduce star halos but I am happy with the progress being made. Currently evaluating PixInsight with a trial version.

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.
