NGC2403 Version A

Image Information

Quoted From SEDS
Explanation:
  • Discovered by William Herschel in 1788.

    This beautiful spiral galaxy is an outlying member of the M81 group of galaxies, and thus about 12 million light years distant.

    NGC 2403 is among the more conspicuous Northern objects which Charles Messier missed when compiling his catalog. Thus its discovery was left to William Herschel.

    One supernova has been recorded in this galaxy so far: Supernova 1954J, which was discovered by Zwicky (PASP 84, 844) on October 24, 1954. This supernova was situated 36E, 100N of the galaxy's nucleus and reached mag 16.0 in its maximum.

    This image is compiled from 31 - 15 minute Luminance images.  RGB data is 13 each for 15 minutes each for a total of 17.5 hours of data used. All data was acquired ACP Web Interface using MaxImDl/CCD version 4.56. Images were reduced and saved in MaxIm. All images aligned using Registar. The data was then brought into CCDStack where bloom removal, alignment, and sigma reject was performed to produce the master image. Photoshop CS 2 was used for curves and levels.  The image data was collected over December 16-20, 2006.
