The Double Cluster in Perseus (NGC869) in LRGB

I took a last peek at one of my oldest favourites, the Double Cluster in Perseus last week after earlier shooting it last September. Mainly to see how my new Antlia LRGB filters perform as opposed to my old Baader CCD filters set. They provide a better color balance and also somewhat tighter stars.

For this image I threw all subs together and also created a synthetic luminance channel from all color filter and luminance subs. Achieving the right color balance (I think) and trying to get the right amount of luminance contribution into the color image took some trial and mostly error but right now I am quite happy with the result. The goal was to bring out the faintest detectable stars in this very rich field without blowing the brighter stars in the core of both clusters out too much.

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.
