M82 - Cigar Galaxy

Giving LRGB a go from the Bortle 7-8 backyard (19.2 mag). It's an uphill battle, and I'll have to recalibrate my expectations compared to backyard narrowband imaging. My Ha data was trashed due to equipment malfunction, so I would like to add Ha in the future. I also lost 2/3rds of my Red data to some weird flat issue. I tried to salvage with a synthetic flat, but the results detracted from the final product more than just using 20 of the good red frames. Still, considering my location and integration time, I'm happy with the result. Galaxy season plus short nights and strong LP will make for some interesting processing challenges this year. Next will be something not as bright to really test the waters. This was also my first target with the Astrondon LP2 light pollution filter as luminance. It seems to work well.

Despite the LP map, I think in actuality my conditions are a little better. I can't image toward the city anyway because of trees, so I focus on east and overhead targets.

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.
