M13 plus a couple of galaxies
Image of M13. Also in the image are galaxies NGC 6207 and IC 4617
Telescope: Celestron Ultima 8 with PEC and 6.3 focal reducer
Camera: Hutech modified Canon Rebel DSLR
Location: Long Island, NY
Exposure: 20x30 second images stacked. 20 dark frames subtracted.
ISO: 1600
Processed with MaxDSLR and Photoshop.
No guiding was used. I think my focus may has slipped a little before I took this image. I used a Bahtinov mask, to initially achieve focus, but after that I had to point the telescope to near the zenith, which may have caused the mirror to shift slightly.
