|NGC 5053: Globular Star Cluster (Coma Berenices) RA: 13h 16.5m / DEC: +17° 41'.9|
Instrument: 10-inch Starfinder
NGC 5053 had been a thorn in my side for several years. However in spring 2002, I made my first observation of this faint globular cluster. It's located in Coma Berenices about 58' southeast of larger, brighter M53. 4.3 magnitude Alpha (42) Comae Berenices is 1.5 degrees due west. According to Skiff, NGC 5053 has an integrated visual magnitude of 9.5 and is 10'.0 in diameter. This suggests a surface brightness of about 23.1 magnitude per square arc second. That's not exactly bright but not extraordinarily faint, either. This should be a fairly trivial object in my 10-inch but previous attempts under murky Midwest skies had always proved frustrating.
