#46 Monthly Summary #3--April/May 2014

There were only three outings this lunar month, and one was for a self-hosted star party on our back deck for some of my music students.  We were also away for a week, missing one or two clear nights on approach to new moon.  Not one of our nights was a fine, clear night.  The final one started out promising, but we saw clouds move in just after dark, and were soon clouded out completely (despite the weather predictions of "mostly clear").

A total of 9 new NGC/IC  objects were observed, and one that was observed many years ago with the 8". Officially, all objects observed were galaxies.  However, I spent my time with a few globulars, doubles, and Mars, Jupiter and Saturn.

LEO
eg 3016: 1'.3 x 1'.1; Mag. 12.9:  One of a galaxy quartet, but my sky conditions changed before I could sort everything out.  Though smaller and fainter than nearby eg 3020, this one is not difficult.  Round, somewhat bright middle, best at 125x.
eg 3020:  3'.2 x 1'.8:  vis. mag 11.9; sb mag. 13.5:  Easy to spot, very large, oval, and a slightly bright middle.  Recommended object.  I will likely have to wait until next year to find the other two.
eg 3837:  1' x 0.9:  Mag. 13.1: In Abell 1367, an area crammed with galaxies.  Don't come here with a 12" scope unless you have a very detailed star chart!  I use the close-up one in the back of Uranometria 2000.  An easy object but not too bright.  With two other NGC at 125x (see below).
eg 3841:  0'9 x 0'4:  Mag. 13.15:  A close pair with the much brighter eg 3842, and a triple with eg 3837.  The is the smallest of the three, a faint, elongated haze that makes a triangle with eg 3842 and an 11 mag. star.
eg 3842:  1'.2 x 1':  A large galaxy, very easy to see, just south preceding a mag. 11 star, one of 4 in a line NE to SW.  Makes a nice pair with eg 3841 at 187x, and a triple galaxy at 125x with eg 3837.
 eg 3860:  1'.3 x 0'.7:  Mag. 13.05:  The first night I tried for this object I could not find it.  However, on a different night it posed no problem.  Oval, faint, but not too difficult to study.  On the preceding side of two N/S stars, and making a triangle with them.
eg 3873:  1'.1 x 1':  Vis. Mag. 12.9:  One of a close pair of galaxies, and the brighter of the pair.  Located just following two stars in a N/S line, not far from eg 3860.  Round.  Double galaxies seen at 125, 150 and 173x.  Recommended pair.
eg 3875:  1'.3 x 0'.3:  Vis. Mag. 13.7:  Fainter, smaller and elongated.  Sometimes it looked like one galaxy, but with good seeing and higher power it was a double!  3875 seen best with averted vision.
eg I. 2951:  1'.4 x 0'.7:  Mag. 13. 65:  Very faint but not difficult to see.  Stellar core noted at 125 and 200x.

BOOTES
eg 5523:    4'.7 x 1'.1:  A nice, bright and large galaxy, though I saw it as clouds and haze were rolling in.  I will return here first in the new session.  Seen previously with the 8", and quite impressive in the 12".  Cigar-shaped and recommended.
