M81 and M82 Deep Integration

This image represents my first attempt at a > 100 hour integration. I always wanted to try something like this, but it was impossible before having an observatory.

I ended up using two cameras (both ZWO ASI 2600MM Pros) because the one on my other scope kept disconnecting and I needed to swap them out as part of the troubleshooting process. This lead to additional unique challenges in this integration as it meant adjusting for rotation before and after camera swaps, shooting multiple sets of flats and assigning different sets of dark frames to different sessions depending on the camera used. It was definitely an educational process: Astro Pixel Processor really made the situation much easier to handle.

Eventually, I hope to have an even faster scope than f/7, but overall even at that relatively moderate focal ratio, the image does display some nice nebulosity around M81 and M82 that I hadn't been able to see with any of my prior attempts. My daughter and I also had fun picking out the innumerable "tiny" galaxies scattered throughout the image when we zoomed in.

I hope you enjoy this as much as I enjoyed shooting it!

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.
