Steve's Notes

===== NGC 2122 30" (10/13/15 - OzSky): Superb HII region and cluster! Unfiltered, at least 3 dozen stars are resolved in a 4' region including several fairly bright mag 12 stars. The cluster and nebulosity is irregular in shape. Excellent contrast gain using an NPB filter at 152x! With the filter, the nebulosity is very bright and large, round, ~4.5' diameter, brighter on the southwest end, irregular surface brightness. A bright, small detached knot, just south of 3 stars, is off the southeast side [3.5' from center]. NGC 2122 is part of association LH 117. Open cluster S-L 740 is 10' SSE and S-L 769 is 23' due east. At 394x; S-L 769 appeared large, round, smooth moderate surface brightness, nearly 1' diameter. A mag 13 star is attached at the east end.
