M81, M82, Friends & IFN (Ha+LRGB)

The weather has been pretty bad this winter with no image nights since the night of February 19/20. Since it looked like I'd only get one night and I wanted to capture Ha+LRGB, I went for 1 hour on each of RGB, 1.5 hours on Ha, and 3 hours on Lum. I selected green as the last filter in case is was cut short but would up with 25.

The total integration time of 7h 45′ is less time than I usually do and I could have used more data. This is my first IFN image and I chose to keep it subtle and not blow out M81 & M82. I definitely could have used more Lum though. With the limited time for color data I'm happy to see some color in the smaller galaxies.

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.
