The Tau Canis Majoris cluster, NGC 2362, in Canis Major. Loose cluster at lower right is NGC 2354. This is a stack of 4 x 8 minute exposures at ISO 1000 with the Canon 5D MkII and Astro-Physics Traveler 105mm apo refractor at f/5.8 with the 6x7 field flattener. Taken from Timor Cottage, Coonabarabran, Australia, December 18/19, 2012.
The Eskimo or Clown Face Nebula, aka NGC 2392, in Gemini. Taken from home March 1, 2013, under excellent conditions, using the AP 130mm apo at f/6, no field flattener and the Canon 60Da at ISO 800 for a stack of 4 x 8 minute exposures, all on the Sky-Watcher AZ-EQ6 mount in for testing, and the Starshoot autoguider with PHD Guiding 1.14 software. It all worked great. The camera shutter was controlled by the telescope hand controller. The little galaxy at bottom is UGC 3873 at Mag. 14.4.
This is the small planetary nebula NGC 2392, aka the Clown Face Nebula, in Gemini. Even shooting with a focal length of 900mm the nebula appears just as a green spot, reminiscent of the appearance of Uranus, thus the name “planetary nebula” given to this class of objects by the discoverer of Uranus, William Herschel. This is a stack of just 5 x 8-minute exposures with the Canon EOS Ra at ISO 800 through the SharpStar 140mm refractor at f/6.5 with no field flattener. Taken from home March 27, 2020.
