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

if i see a person struggling with english and still trying to make educational content about niche topics no one else covers, i have the upmost respect for them

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
