NGC 4565 in LLRGB

Given the issues I have been having with adding RGB colour to my luminance frames recently, I was so relieved to see that my attempts to bring this galaxy alive, have been largely successful. I did not have problems with my flats; however, messing with the spacing between my camera and f6.3 focal reducer has unfortunately just clipped the top of this fine galaxy and 'severed' NGC 4562, which is a shame.

Captured in Envisage, aligned and stacked in Nebulosity, and processed in Startools, using the default workflow. Colour rendition was straightforward, using a scientific colour constancy, and isolation to push back the noise and remaining gradients. A little healing to some artefacts remaining from my flat frames, et voila.

Description: Reprocessed with slightly better noise reduction and colour, I think. I could not extract any further detail - a combination of poor seeing, and collimation, I expect.

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.
