Final edit with new data from Bortle 4! Amazing how much better off things are just adding a couple nights of darker sky data. First galaxy RGB image on my new Askar 130PHQ setup after getting everything set up and working. The Ha added in helped bring out some of the finer details in M82, and added some nice details to the arms of M81. Interestingly, there’s a heavy pocket of red southeast of M81 which appears to be some kind of very small emission nebula. In total, it looks like there are around 35 named galaxies in this image, in several more I found looking around that weren’t named (at least not within the PI catalogs for image annotation). Overall I’m satisfied with this image and appreciative to have some imaging time this month compared to how the last few months have been!

Data taken 2/28, 3/4, 3/5, 3/6, 3/13, 3/14, 3/15, 3/19, 3/20

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.
