Description

Markarian Chain LRGB 3-Panel Mosaic

A view of the Virgo Cluster of galaxies.

Here I have combined 30 sec mono L subs from the ASI6200MM camera at 2x2 (gain 100), with 60 second OSC subs from the ASI128MC (gain 132), for each of three panels of the final mosaic.

For best viewing download the original file.

Happy galaxy hunting! --I've included a cheat sheet in the revision photo...
