Messier 81 Bodes Galaxy

I previously imaged M81 using an 11 inch SCT and a ZWO ASI2600 one-shot color camera.

I recently bought the monochrome version of ZWO ASI2600 along with a ZWO filter wheel and Baader CMOS filter set. This is my first attempt at LRGB imaging and LRBG processing.

With prominent, clearly defined spiral arms, Bode’s Galaxy is an excellent example of a grand design spiral.
Messier 81 is the largest member of the M81 Group of galaxies, a group that contains 34 galaxies located in Ursa Major. The M81 Group includes the Cigar Galaxy (Messier 82) and NGC 3077, two galaxies that are strongly affected by their large neighbor.
The gravitational influence of M81 has left all three galaxies stripped of hydrogen gas.
The interactions between the galaxies have allowed interstellar gas to fall into the central regions of Bode’s Galaxy and NGC 3077, which has triggered vigorous starburst activity there.

The galaxy’s size and proximity – it is one of the nearest galaxies beyond the Local Group – often make it a target of study by professional astronomers, while amateur astronomers and astrophotographers like to observe the galaxy because it is large and has a relatively high brightness.

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.
