M31 Andromeda Galaxy (LRGB+Ha)

M31 Andromeda Galaxy- my first attempt at imaging a galaxy using my Redcat51 and ASI294MM (LRGB+Ha). When I started this project, I assumed it would be fairly easy to capture and process as it seems like its one of the more popular targets in the sky. To my surprise, this was not the case...

The capture portion went very smooth. I got lucky with clear skies and cool temperatures with minimal dew. I was fortunate to complete imaging over the course of three nights and capture about 11.5 hours of data across all filters. However the processing in PixInsight proved to be a challenge. I really struggled with my masks and using below average calibration compounded my frustrations. I continually battled a slow computer, little to no patience, and not saving my project/images frequently. I got happy fingers several times and just clicked processes in no logical order resulting in a lot of wasted time.

I finally settled into my chair and slowly stepped my way through each processed involved, watched many videos, and questioned my helpful club members. In the end, I am "satisfied" with the final product. This is not a race, its a journey. As long as I continue to move forward, its a victory in my eyes.

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.
