MARCH 2016 OBSERVERS CHALLENGE – NGC-2392
NGC 2392 – Planetary Nebula – Gemini
Date: February 2016
Observer: Roger Ivester
Telescope: 10-inch f/4.5 reflector
Sketch magnification: 190x
FOV: 0.32º – 19 arc minutes
Description: Very bright, bluish ball, appearing as a blurred star at low magnification. When increasing the magnification to 190x, the central star is easily seen. The edges are well defined, with a darker patch noted on the SSW edge. When increasing the magnification to 267x, using a 12 mm plus a 2.8x Barlow, the nebula became granular.
Date: January 31, 1998
Telescope: 10-inch reflector@ 256x (12.5 mm plus 2.8x Barlow)
Very bright, round, bright central star, with well defined outer edges. Greater concentration on SW edge.
Date: February 8, 2008
Telescope: 10-inch reflector@ 190x (12 mm plus 2.0x Barlow)
Much brighter than double planetary nebula, NGC 2371-2372 also in Gemini. The nebula is very bright, round, but has a hint of N-S elongation. The central star is easily seen at all magnifications. RI

The following image was made by Jim Gianoulakis of Las Vegas. Can you see the face of an Eskimo, or how about a clown-face, or maybe even the face of the beloved character, WC Fields?
