Adjustments in Photoshop. Only brought in levels a little bit and adjusted vibrance/saturation. Didn't feel I had do do much else. There was some light pollution from a nearby street-light, but the stacking software obliterated that for me.

Data from two consecutive nights. Forgot to charge the laser, so that one died while I was aligning. Had to do the final adjustments old-school - on my knees using the polar scope and the Polar Finder app instead. Worked fine, might even have led to more accurate tracking?

This little tracker (MSM) continues to impress me. Out of all the ~180 images I took those two nights I only had to discard about 5 of them - and that was because of planes and satellites. Tracked pin-point with 30 seconds exposures at 200mm with a combined payload of just below the 3kg limit. (used a kitchen-weight).

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.
