The Whirlpool Galaxy (M51) - March 13, 2021 and April 27-28, 2022

It has been a while since I processed HaLRGB image, I must say I always do like the look of the final image both colors and details, but it is a lot of work, capturing all these subs with different filters requires multiple nights and not to mention the processing steps are always time consuming and complicated to put everything together.

As I mentioned this was multiple nights work were I captured 24x300s of Ha data on 3/13/2021 using ASI183MM camera (which I sold) and 139x180s (Lum), 30x180s (Red), 30x180s (Green) and 30x180s (Blue) on 4/27-28/2022, which is a total exposure of 13.45 hours

Stacked, combined, processed to get the final image using AstroPixelProcessor, PixInsight, Astrosurface-R3, Luminar4 and Photoshop, I do hope you like it.

Equipment used
Celestron 9.25" with 0.7x reducer
ZWO ASI183MM and ASI2600MM Camera
Astronomik Ha, L, R, G, B filter
iOptron CEM60 mount

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.
