M31 Andromeda Galaxy

Many people start their astrophotography journey with M31. I certainly did. So shooting it every year is like a ritual to check how far I have progressed. I took a night to shoot the target to test my newly acquired ZWO ASI2600MC Pro with Vixen FL55SS scope and 1.01x f5.5 flattener. The shooting went well, but after stacking the image I was surprised to see comet tail-like artefacts on stars, like those we'd see on a not-properly-corrected reflector. I think it was caused by the weight of the camera making flexure of the image train and throwing off the collimation. Thankfully it can largely be fixed in post-processing. As for the color, I tried a more dramatic approach. It's probably not realistic, but I think it looks pretty. 🙂

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.
