M81 and M82 Through the IFN

The Integrated Flux Nebula in the region of the sky around M81 and M82. I shot this over 5 sessions with my mono-converted Canon 60D and H-a modded Canon 600D with my Rokinon 135mm f/2 lens and iExos-100 mount. Three sessions went to luminosity data with the mono DSLR, and the other two for RGB with the other DSLR. The subs from the two cameras were integrated separately and then combined as LRGB in Astro Pixel Processor. Each session was calibrated with 30 each darks, flats, and dark flats with an additional 50 bias to scale the darks.

The LRGB image was then run through Starnet++ and brought into GIMP for finishing touches and star reintroduction.

Description: Hazier version with a more generous sprinkling of smaller stars. I found the star color a little distracting so desaturated it a bit. Although I lost a bit of the definition in the IFN, I like the more subtle dust clouds.

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.
