A Segment of Markarian's Chain

[Davide Simonetti]

An annotated an unannotated segment of Markarian's Chain which I'm targetting for the first time. I'm planning to get some more shots of the chain and stitch them together in order to show all of it, so this is just a first panel and a test of exposure and processing settings.

This image is made from 29 x 30 second exposures at 3200 ISO and 18 x 30 second exposures at 6400 ISO plus 19 dark frames, 16 flat frames and 48 bias/offset frames (applied to flat frames only). Total exposure time 23 and a half minutes. Images taken on April 30th 2015. Processing was done in Nebulosity and Photoshop.

Thanks Michael, I'm looking forward to completing the whole chain
