The supercheapo 76/700 or 76/900 Newtons even with the tiny EQ2 or whatever the Minimounts are called can be, with some advice maybe from astrotreff.de or the astrocommunity of your choice, a really good starting Point!!! My Seben 76/900 outperforms the kids-scope-tasco-refractor in dimensions!!!! Especialy when upgrading the ultracheapo eyepeaces with only supercheapo eyepeaces from AliExpress or used on ebay!
Jep there are many good scopes for not much money. Maybe I should consider doing a video about those scopes :-) But you need the underlying principles to get a grip on their specs. Thank you Andre for your scope suggestions! Clear skies!
I would bet that the 76/900 or 76/700 is THE most used sold Newtonian in Germany at all! There must be an humongous fabric in china grinding trillions of 76mm-mirrors 😁😁
I have one of these 10:36 cheap 76mm 700mm telescopes. How do they optically compare to something more professional? I mean just the mirror(s), not including the mount woubble, high tolerances in the focuser overall build quality etc. Could I combine 3 or even 7 of the primary mirrors to get a bigger aperture to create something like the Giant Magellan Telescope? I assume the mirrors in these cheaper telescopes are spherical, so as long as the bigger off axis angle doesn't ruin everything...or am I too unrealistic? I think a little functional model of the Giant Magellan Telescope would certainly look cool, but would it optically make sense with these mirrors? 🔭 x 3 = 🌌 ? 🤔
Haha!! I LOVE the idea but am highly in doubt about the practicability... To your question: the optical components of my BRESSER telescope are of very good quality. The main mirror is parabolic and delivers good quality images. The parabolic mirror is a problem when arranging in bigger constellations. Second problem to my understanding: by combining separate mirrors you also add the individual optical errors to a big total error. But on the other hand: such a scope - what a cool thing to imagine :-D Clear skies!!
@@catchingphotons Thanks for your response. Yes, collimation will probably be a nightmare :-) I hope it won't take me as long as it's taking for James Webb ;-) Your assessment of the optical quality of these mirrors encourages me to try it out. If it's not working at all, I have some other ideas to try out with a few telescope mirrors.
I've not jet done a video about guide-scopes but this will definitely come along. I use the Omegon 50/200mm guidescope with helical focuser and it works like a charm up until now. Clear skies!
Thanks for this! As a beginner, I've been looking all over for this info!
Thanks Brandon! Glad the video was on any help!! Clear skies to you!
This series is a god gift, thank you so much!
🙏 thank you for your encouraging comment!! Clear skies!
really thankful for the series of this video
You are very welcome! Thanks for your kind comment. Clear skies!

Hello Chris! You mention the good guide scope. Can you show in which video?

Clear skies!
Good refresh!
Thanks! Glad you liked it! Clear skies!
