M31 - First Attempt

This is my first real attempt with the AT72EDII to get something a little wider field of view. The weather in San Diego county this year has been "challenging" for astrophotography, but I got a few hours last night. Not nearly as much as I hoped for, but it was enough to try this target, which was very well framed with this particular setup. It also is the first time I'm trying out the Askar Filter Drawer -- btw, note that I had to use a ZWO IR/CUT filter because the Gosky LP filter is too think to fit in the drawer! -- along with some extension accessories.

The SNR was fairly poor later in the evening -- too much humidity in our sky -- and I was only able to use 36 of the 80 or so subs I took. Something is going on with the lower right corner, I think it shows up on later frames, and not earlier ones, which prevented proper correction using flats from occurring. Maybe something (dust, dew drop?) fell on the objective partway through the evening?

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.
