This is my first attempt at imaging M53 with my Nikon Z6ii, SkyGuider Pro, Nikon 500mm f/5.6 PF ED guided with my ASI Air Pro. I decided to edit the raw frames in LR first, second stack in Sequator and then edit the stacked version in LR again. Came out better than I thought with not a lot of work. Certainly could be better and I have a lot to learn but I can identify the object and I'm generally happy with the outcome. I can see a dedicated astrocamera will be in my future due to the color cast which I believe is from my sensor and cant really be removed without a lot of manipulation which can make things worse. This color cast issue is supported in a CN forum in a lot of detail. I didn't get the concentric coloring discussed but still have the noisy purple background.

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.
