A two frame mosaic of IC 443, NGC 2174
IC 443, also known as Sharpless 248 (Sh2-248) or the "Jellyfish Nebula", is a supernova remnant in the constellation Gemini at distance of about 5000 light years. The actual size of the SNR is roughly 70 light years. This image spans about 10 degrees of sky. (Twenty Moons side by side in the sky.)
At top Right lays an open group, Messier 35.
At bottom Right, the Sharpless object 247, Sh2-247, can be seen as a bright dot.
NGC 2174, the "Monkey Head Nebula", (OCL 476 or Cr 84) is an open cluster surrounded by emission nebula in Gemini at distance of about 6400 light years.
Processing work flow:
Image acquisition, MaxiDL v5.07.
Stacked and calibrated in CCDStack2.
Levels, curves and color combine in PS CS3.
Optics, Canon EF 200mm camera lens at f1.8
Guiding, Meade LX200 GPS 12" and a Lodestar guider
Image Scale, ~5 arc-seconds/pixel
Only four 1200s exposures of H-alpha emission for both panels.
Other channels, O-III and S-II, are from an older image of mine.
