Wow that quite the telescope! This is basically what i wanted to build just smaller and and with a Reflector scope instead of a Refactor scope, thank you very much for this informative comment :D

thats what i was thinking :/

Tubeless telescopes exist tho, i saw some big diy newtonians that did not have any

entrance pupil isn’t well defined

oh right, i didnt thought about that, maybe i could add some sort of shroud to the light inlet

I already ordered a first surface mirror to test, i will report my findings :D

communication satellite, not for espionage

Mit Rezept ja

Wenn ich mir kein Brot mehr leisten kann werde ich reiche essen.

I have seen Bias Tee injectors for up to 50v@1.5A, thats enough for a decent output booster. But yes in reality 99% of those where used for preamps in analog TV/Radio Rx

Naja das tuen die ADAC und Rettungs Helis gelegentlich auch…aber solange der ADSB transponder an is sieht man sie trotzdem aufm radar. Was auch immer da nachts geflogen is hatte seinen Transmitter definitiv aus
