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 pencil sketch was made using a 10-inch Newtonian reflector, with a blank 5 x 8 notecard, with the colors inverted via computer.   Roger Ivester

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?
