Markarian's Chain in Virgo

My first attempt at capturing Markarian's Chain was a bit of a miss, as I had the wrong coordinates and ended up with a nice photo of M61. This time I got the right target, and went extra deep with the data collection. Yet I still feel like I've got too much noise in the final result. This whole region of the sky is fun to process, as there are tiny galaxies in every direction. It's hard to decide where to crop.

Description: Big change in my post-processing routine, which I think I'm going to follow from now on (at least for broadband images). Instead of importing the raw tif files into photoshop for stretching and compositing, now I'm compositing the channels in Siril and using the photometric color calibration function to get an accurate color balance. I'm also doing some stretching there, as it seems easier than doing it in photoshop. However I think I went too far in the initial stretch this time, as the bright stars look like planets now. Always room for improvement.

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.
