NGC205 - Companion to Andromeda Galaxy
with 10" f/3.9 Astrograph
Uploaded 11/3/16

I had not imaged this bright elliptical galaxy for over a decade, back when I was using an ST-7 CCD camera. This new image is far deeper, and easily reveals the gravitationally warped wings on this satellite galaxy which i brought out more clearly in the second histogram equalized image. At lower left in these images is part of M31.

Histogram equalized view. This is a mathematical function which forces the histogram to have nearly equal values for each brightness level. Note the faint wing like extensions from the upper left and lower right which represent the sprays of stars thrown out of orbit by the huge primary galaxy M31 by its gravitational influence.
