William Optics RedCat 51 250mm telescope
RedCat 51 APO 250mm f/4.9

This is the sexiest piece of gear I own – and like all my sexy things, it unfortunately spends most of it’s time in the closet.

I got onto the kickstarter for this beautiful piece of glass right before it closed, meaning I was one of the first to try this puppy out. It couldn’t have come at a better time, as an astrophotography-related wrist fracture meant carting my 8″ SCT around wasn’t going to happen.
