The Sculptor Galaxy, also known as the Silver Coin or Silver Dollar Galaxy, NGC 253, an intermediate, starburst spiral galaxy in the constellation Sculptor, about 11.4 million LY away, undergoing a period of intense star formation.
This photo was imaged in natural color through my 8" Celestron SCT at 2032mm focal length using my astro-modded and cooled canon 40D DSLR and tracked with a CGEM mount.
I imaged this galaxy when the moon was nearly at first quarter and in the same general direction as the galaxy, so I used the Neodymium filter (AKA Moon and Skyglow filter) instead of the UV/IR Cut filter to try and control the moon glare, I think it worked.
Total exposure time was 5 hours 41 minutes.
