Description

The data for this image are from Telescope.Live.  The scope (Planewave CDK24 equipped with a CCD FLI Proline PL9000 camera) is located in Chile.   The focal length is 3962mm with a resolution of 0.62 arcsec/pixel.  The data consisted of eight L, R, G, and B images, each with an exposure of 600 seconds for a total of 1 hour and 20 minutes.  The biggest challenge in processing this image was the removal of hot pixels.  Cosmetic Correction removed 1000s, Photoshop Dust and Scratches removed most of the remaining 100s, and hand editing the rest.   With only two images per filter, statistical methods of removing them are of limited value.
