William Optics RedCat 51 Petzval APO!
Hey guys - For anyone interested in taking a closer look at this tiny Petzval APO from William Optics, you can check out my first look and unboxing video: https://astrobackyard.com/william-optics-redcat-51/
The design goals for the RedCat included creating an affordable refractor that uses the highest quality glass, and delivers a flat imaging field for unmatched color correction. I was in contact with William along the way and saw each step of the process - including when he decided to put the cat face on the lens cap! LOL
