Observations of Abell 1367

Some of this may be quite premature, but the forty galaxies I logged from Fremont Peak the evening of 03/05/03, which were within a degree or so of NGC 3842, are listed below. All of these were observed with my 18" f/4.3 Newt/Dob, with magnifications ranging from 133x to 377x. I don't know how many of these particular galaxies are truly associated with Abell 1367, and I still need to verify that the positions, identifications and descriptions listed in TheSky are accurate. I still have a *lot* of homework to do here, mainly through the NED site ( http://nedwww.ipac.caltech.edu/).

As I went along, my very poor excuse for "brightness" descriptions just became more and more subjective, so don't put much faith in these. As is obvious, I didn't spend much time on any one galaxy. Once I had it identified - generally in a small group environment - I just logged the faint fuzzy without any more of a personal description than I have here.

In addition to the items listed below, I have six other galaxies listed as "suspected." There are many more galaxies relatively nearby, too, a few of which may well be part of Abell 1367. I definitely plan to spend a few more nights here.

In the order in which I logged them, and using the primary ID as carried by TheSky:
