Attached is an image of Markarian’s Chain of galaxies in the heart of the Virgo Galaxy Cluster. The chain of galaxies stretches from M84 to NGC 4477 and according to Wiki, the chain was named after the Armenian astrophysicist Benjamin Markarian, who discovered their common motion in the early 1960s. The image consists of the following sub-exposures: L 21x120s unbinned; RGB 16x120s all binned x2, giving a total exposure time of 2 hours 18 minutes. I took the images on the night of 6 March 2021 from my back-garden observatory in Oxted. I used a Takahashi FSQ85 ED (3.5 inch) refractor operating at f/5.3 mounted on a Paramount MX using a Moravian G2 8300 cooled CCD camera and Lodestar 2 guide camera. Image capture was done with Maxim DL and I used CCD Stack2 and Photoshop CS5 for further processing and annotation. Thanks for looking.
