M81 M82 Ha LRGB

This is my first real attempt at galaxies since coming back to the hobby. It is certainly a lot harder to process than the nebula and narrow band stuff. The image was shot with tandem rigs Edge HD 8" For Luminance at f10 (didn't have my FR working at the time) with the ASI 6200 mm Pro and an FLT 132 at f7 for RGB and f5 for Ha. I might try for more data from darker skies as this was all from my back garden Bortle 7. I think I'll re try the luminance at f7 if the skies cooperate, now that I have my reducer set up and guiding well.

Exposures as follows (total 23 hours 40 mins):

Luminance Edge HD at f10 BIN 2 ASI 6200 MM Pro 44 by 600 s (7 hours 20 mins)
RGB FLT 132 at f7 ASI 2600 MM Pro 12 by 600 s each (6 hours)
Ha FLT 132 at f5 ASI 2600 MM Pro 56 by 600 s (9 hours 20 mins)

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.
