My good friend in Chicago, USA, Frank Mcabe kindly brought my attention to a very interesting Deep Sky article in Sky & Telescope magazine by Ken Hewitt-White “Small globular, tiny galaxies’ which takes a look at faint galaxies close to the not so dazzling globular cluster NGC 7006 in Delphinus. On this end of the working week evening the sky offered me the opportunity to take a look for myself.

Now Ken observes visually with a 17.5” telescope so I was confident that my own 20” video assisted set up would catch all that he had seen and more.

My first intention was to get mag 10.6 NGC 7006 onto the monitor and then get the galaxies closest if they fitted down as a sketch. This worked well; the globular took a little while to sketch to a point that I was happy it was a reasonable representation. PGC 65907 which is the closest galaxy to the GC stood out nicely and then to the upper right in my sketch we can see upper most the nice edge on PGC 65908 elongated N-S this forms a galaxy triangle with PGC 1501723 which showed as having a ragged profile on my monitor and another tiny smudge of a galaxy noted as “anon” by Ken which is very close to a star. This I must say was a very pleasing observation 🙂

Next again prompted by Ken’s notes I pushed the scope just over the border into Pegasus which was a close hop away to look at NGC 7034 & 7033, these close pair at mag 13.8 and 14.1 respectively are interesting enough as a 2 for 1 view but don’t even hint at structure, what was more exciting was the faint pair of elongated smudges to the left in my sketch (which actually turned out to be 3 galaxies when I researched) http://dso-browser.com/dso/info/NGC/7034/galaxy

Finally I noted an open cluster close by on my planetarium software so before closing down I decided to take a slew there. I panned around a little until I was sure I was in the centre of the cluster, unfortunately it was too large to be accommodated in my approx 12’ x 12’ fov. Once the image settled I turned up the exposure and revealed 3 close galaxies, in a line E-W and obviously faint, all had differing outlines, I was unable to identify but feel they made a nice view & sketch.
