hello, I have a 76mm aperture reflector telescope, it came with the wrong manual! *bought second hand” and I’ve built it as close as what I can tell through the other manual and searches from YouTube! I’m beginning a career in astronomy starting Oct 2021 and wanted to get a taste of what I could see! The moon is bright right now! I can see it through my aim scope but the second I put a lense in and look through the actual scop I can’t see a thing!! I’m just getting very stressed and wondering if anyone could kindly help with some tips, thank you.
