NGC 224 (M31) And

This is a mosaic of 3 images, each of 60 seconds The images were taken with a Pictor 1616 attached to an Meade 10" F/2 telescope. The exposures were unguided. Each of the images was corrected with a dark frame and a flat field. After combining, the image was logarithmically stretched. North is to the left.

This is the result of binning 4x4 from the original image. (Click here for full resolution)

I am still learning how to flat field the wide (1.5 x 1 degree) fields. At the time of imaging the galaxy was at an altitude of 30 degrees. I took only one 60 second exposure for each of the three locations. There was a hint of barrel distortion in the merged image.
