The Leo Triplet


I have been itching to image these galaxies since getting my Nikon D7000! We have succumbed to strong winds and clouds for the last two months, but tonight was clear and calm. I headed to a spot about 20 miles north of my home, set up and started shooting. Pretty chuffed with the result! I can maybe process out a bit more noise, but that might be light pollution.

Image Details:

  • Imaging Scope: Astrotelescopes 80mm ED Refractor
  • Imaging Camera: Nikon D7000
  • Guiding Scope: William Optics 66mm Petzval Refractor
  • Guiding Camera: Meade DSI-C
  • Mount: Celestron CGEM
  • Exposures: 7 * 7 minute lights, 5 * 7 minute darks
  • ISO 640
  • Aligned and Stacked in Deep Sky Stacker
  • Post-Processing in GIMP (contrast, saturation and unsharp mask)
  • Noise Reduction in NeatImage
