Astrophotography by Eddie Guscott

M31- The Core of the Andomeda Galaxy
The core of this enormous galaxy is normally so bright that it saturates on most sensors, whether film, CCD or dSLR. By optimising the sub-exposures to avoid this saturation, it is possible to process the image to reveal detail within the core area which is normally to bright to be seen.

Date/Location: Luminance from Equinox Star Party, Kelling Heath, Norfolk  20 September 2006
Equipment: 130mm f/6 TMB refractor on AP900 mount
Camera/Exposure: ST2000xm ccd camera - L = 30 x 120seconds binned 1x1
   
Notes: The colour data was taken from an older image through a smaller telescope (image here).
The image appears odd because we normally see this part of the galaxy as being very bright. The brightness levels have been subdued enormously to better display the core detail.
