Description

Simeis 147, which looks rather like a cosmic brain.

My first mosaic - consisting of just two frames for this initial attempt.  Also my longest integration to date, with 10 hours per filter (Ha and OIII) per pane - 40 hours total.

Most frames were taken over a couple of weeks in late January to early Feb, but I had some test data from last October that I threw in as well.

HOO (50/50 for green), along with some short RGB exposures for the stars.
