M31 RGB (OSC) - The Andromeda Galaxy

This stand as a test of the Nikkor 300mm f/2.8 AFS with the coupled Hoya IR Cut filter for broadband targets. A classic in its own way. I am convinced that many of the pictures you see of the said galaxy overemphasize the blue overtones of the outer rim, at least at this image scale. So, in a way, I feel this is a more faithful reproduction of the "natural colours" of M31 than those taken with RGB filters which make ot easier to "pump up" the blues stragglers contributions to the overall colour cast. Overall, I think the overall colour cast of the lens, filter and camera tend to veer a bit toward the green end of the spectrum and needs a slight correction increasing the blue contribution by around 10%.

Description: Another rendition as I'm not very happy with this data set (specifically the colors are rather muted with a preponderance of green which I think is due to an IR leak at some point), hopefully bringing the OB stars-dominated areas more in evidence. It is clear that I'd need to have another go at it with a more selective filter at one point in the future.

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.
