Very nice! But you won't beat this ;)

> Optical Engineer Rik ter Horst shows us how he makes very small telescopes (at home) which are intended for use in micro-satellites.

Rik's monolithic Cassegrains are the perfect example of the blend of amateur and high-end professionnal work in astronomical optics, thanks for linking it ! His amateur work is incredible, like this 16" CDK : https://www.cloudynights.com/forums/topic/558284-a-400-mm-f1...

Dayyum, those shots are incredible! I've seen worse pictures from professional telescopes.

This coming year ... if the crik don't rise (as it does with some regularity). Some of you may be able to take a picture of yourself with one of Ril ter Horst lenses as it will be launched in a 2U cubesat named OreSat1 by Oregon's Portland State University undergrads.

pictures would be captured by hand held groundstations
