M31 Fourth Attempt

Hello!

I went out last night and imaged M31.....Again! I'm really just trying to figure out the exposure thing and working with the histogram. The attached image is just over three hours of exposure. 121 x 90 second lights, 30 darks and 30 flats. I stacked it in Deep Sky Stacker, stretched and color balanced in PixInsight and did very little processing in Photoshop. I simply worked the black point and did some modest curve stretches. No color has been added, nor did I add star diffraction spikes. I did run a light RC-Astro GradientXTerminator to clean it up a bit.

My equipment is - Celestron CGX mount, Orion 8" f3.9 Newtonian, QHY294C imaging camera, ZWO120 mini guide camera, Orion mini guide scope, Sharpcap and PHD2. No filters were used. For the first two hours I had to contend with lights from a soccer field less than 100 yards behind me. I don't know if that impacted the image or not.

I'd love your thoughts and input. I kept this natural and as close to the stacked and initially stretched image as possible.

Thank you!

Scott

Description: I went in a sharpened the entire image a bit, just to bring out more detail. I also added some star diffraction spikes.

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.
