Observation Notes
4147 COM GLOCL 12 10.1 +18 33 10.3 4.0' H I 19 Bright, pretty large, round, bright middle at 165X. Five stars are resolved in good seeing. A nice globular to break up all these galaxies.

4414 COM GALXY 12 26.4 +31 14 10.9 4.8'X3.2' H I 77 pretty bright, pretty large, elongated 3X1, much brighter middle at 100X. At 165X, stellar core comes and goes with the seeing.
4419 COM GALXY 12 27.0 +15 03 11.6 3.1'X1.0' H II 113 pretty bright, pretty large, much brighter middle, much elongated at 100X.

4459 COM GALXY 12 29.1 +13 59 11.6 3.5'X2.7' H I 161 pretty bright, pretty small, much brighter middle at 100X. At the edge of the Coma Galaxy Cluster, so there are four small, faint companions in the 40' field of view.
4473 COM GALXY 12 29.9 +13 26 11.2 3.6'X2.3' H II 114 pretty bright, pretty small, round, much brighter middle, has a very faint, round companion to the NW.
4477 COM GALXY 12 30.1 +13 39 11.9 3.8'X3.5' H II 115 Bright, large, considerably brighter middle, round. 12th mag star on the south side.
4494 COM GALXY 12 31.3 +25 47 10.7 4.5'X4.3' H I 83 bright, pretty large, round, much brighter middle at 100X
4548 COM SBb 12 35.5 +14 30 11.5 5.5'X4.5' H II 120 pretty faint, pretty large, somewhat elongated, somewhat brighter middle. Marked M 91 on U2000. Messier gave a position near here for an object "dimmer than M 90". Shapley says it may be a comet that got away, NGC 4571 has been suggested. Owen Gingerich says it was a duplicate observation of M 58.
4559 COM GALXY 12 35.9 +27 58 10.7 13.0'X5.2' H I 92 bright, large, much elongated 3X1, somewhat brighter middle at 135X. Three stars involved in south arm make this object unique, don't miss it.
4565 COM Sb 12 36.3 +26 00 10.3 15.5'X1.9' H V 24 very bright, very large, extremely elongated 10X1, very bright middle at 135X. Dark lane is easy at a good site, it can be held with direct vision. At 200X some fine detail within the dark lane is visible in moments of good seeing at our best sites in the mountains of northern Arizona. It has always looked like the classic flying saucer. At a Saguaro Astronomy Club star party someone called it "God's Frisbee". This spectacular edge-on galaxy is also a companion to Comet Coe. The story goes like this: I had just completed a new 17.5" Dobsonian and had had only few chances to get it out into dark sky. I trucked it to a club gathering at one of the best sites we use. When I observed NGC 4565 it had an obvious companion that I immediatly thought was a comet. After showing it to A. J. Crayon and several other club members, I looked it up and it was quite obvious in a photograph in Burnham's. Oh well, so much for fame 4565 and fortune. Several "friends" pointed out that it could be a very long period comet that is coming directly at the earth.
4689 COM GALXY 12 47.9 +13 46 12.8 4.0'X3.5' H II 128 pretty faint, pretty large, somewhat elongated, not much brighter middle at 100X.
4725 COM GALXY 12 50.4 +25 33 10.2 12.0'X9.0' H I 84 bright, large, much elongated, very bright middle at 100X. My old 17.5" would show a hint of barred spiral structure at 125X, but I have not had the chance to use the 13" on this object from an excellant site to see if the smaller scope will duplicate that feat.
