Markarian's Chain RGB (OSC)

Wide field shots of galaxies groups are one of my favourite although is probably fair to say I envisioned a bit more toward image scale than the present one. I'm not totally dissatified nor I am fully satisfied with how it turned out. Sure, shoting south with a 300mm lens is frought with dangers in the guise of a host of horrible gradients (which I did my damned best to hide in the shadows) and I wasn't that keen on keeping the focus just right which is tricky (to say the least) in a f/2.8 lens. Still, I haven't got anything better to show for my efforts and the only sure-fire cure to the chroma noise still apparent is more shoting time and that window of opportunity is as good as gone this year.

1st revision: I didn't push the stretching that far and that allows for softer stars (which, to be honest, aren't great to start with) thus avoiding using NR at all, which I much prefer.

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.
