Galaxy Cluster Abell 1367

Galaxy Cluster Abell 1367

I observed this galaxy cluster in the early morning hours just after midnight on March 27/08. I have been compiling an observing log for the RASC Deep Sky Challenge list and was sure I had observed this group but couldn't find a note anywhere. Consequently this meant I needed to reobserve it. (make a note here to be a better documentarian) Luckily on th night after a long 12 hr drive home from the Kootenays through snow storms, the sky over my back yard was beautifully clear with a SQM reading of 21.14. I put my f/5 12.5" dob out and set to the task.

This grouping is approximately one degree to the south west of 93 Leo, which is just north of Leo's tail. This is the view as I saw the core of the cluster at 182X with a FOV of approx 0.45 degrees. The actual cluster occupies almost a full degree of space. The brightest galaxy of the group, NGC 3842 is at the center. There are only 11 stars in this sketch, with all of the rest being galaxies, including the one just out of the circle.

I also took the opportunity to observe the smaller galaxy cluster Copland's Septet while I was in the area. It lies just off 92 Leo. I didn't get a chance to do a sketch, because shortly after confirming 5 of the 7 galaxies in that group the sky clouded over and it began to snow!
