M31 - The Andromeda Galaxy

The Andromeda Galaxy under varying conditions.

First time trying Andromeda with my new telescope.
This was imaged over three separate nights with two different cameras and varying degrees of moonlight.
The first night was imaged using a stock Canon EOS 5D MKII (full frame) and the two other nights an astromodified Canon 700d (crop sensor) was used.

Imaging broadband targets under a 98% and 100% moon is a fools errand, but I was itching and the goal for the night was to practice and configure plate-solving. I chose Andromeda as it is a target that is easily recognizable in single exposures. When i had gotten it working, I figured I might as well image anyway as the setup was running fine.

Astro Pixel Processor was able to combine and allign the datasets taken with different cameras fine. The post-processing was challenging to say the least as the moonlight really washed out a lot of what could have been. I still don't think it turned out too bad, in spite of the gradients. Will definitely try this again under more optimal conditions.

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.
