Markarian Chain

As an experiment, I swapped out my mono 6200MM camera for the 2400MC OSC camera on my Hypergraph8. With this set-up, I decided to image the Markarian Chain - simply because a) I had attempted it before and b) it was about as well positioned as it was going to get for the year from these parts. [Albeit since remaining below an airmass of 2 for most of the observations]

Despite elevation, my poor seeing and the RGGB Bayer matrix all being against a detailed images, I was interested to see just how much I could recover with the RC Astro tools

The result surprised me. Through a careful itnerative process, I was able to extract a fair bit of detail.. I partcularly liked the detailed in M84 and M86 with both giant ellipticals showing structure in their stellar envelopes and a pleasing colour gradient out from their centres. I may have pushed the saturation a little too far, but I still like this more colourful version.

While it doesn't compare with the best out there, I don't think its too bad for an OSC and an average z.d. of 64degrees.

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.
