Galaxy NGC 2997, in Antlia.  About 55 mln light years away.


Image info

Telescope:  Skywatcher 8" f/5 Newtonian

Focus:  Prime focus

Camera:  SAC7B, uncooled

Exposure:  69 x 25s 

Date:  12th March 2003

Processing:  Acquired in K3CCDTools as AVI.  Stacked in Iris.  YRGB image, composited in Photoshop.  Colour enhanced using Multiple Luminance Layering.


Taken in conditions of poor transparency, and with insufficient no. of frames.  The image is still unsatisfactory but is interesting for the use of a technique in Photoshop (I'll write more about this some time) to enhance the brightness of the galaxy itself against the sky background.
