Product Details

  • Designed for a better astrophotography experience than its doublet predecessor, the SharpStar 61EDPH II apochromatic triplet is improved in a few key areas. Bringing in an improved ED element to the multi-coated glass and paired with a focal length of 335mm and focal ratio of f/5.5, this telescope provides fast light-gathering capabilities across large sections of the night sky. The included 0.8x focal reducer will bring the focal ratio down even further to f/4.5!

Sharpstar 61mm Triplet APO Refractor Telescope

I use this OTA for wide field AP and I think it's a great little scope. Nice sharp stars all the way to the edge and the colors are great.

Same as the Raptor

Owned one of these for years. It is the same scope as the Raptor61, just pre new paintjob and new rings. They are the exact same scope. Excellent optics, perfect size.
