Telescope formula s
Hi everyone I'm going to ask a really dumb question.
"How far can my telescope see.?"
Of course to answer this we need to have some detail and basic assumptions
1. It is a perfect night for viewing, no moon dark as dark can be, like the Milky Way stretches way across the sky. No dew everything perfect.
2. The scope I,m using is a 10" dobsonian, focal length 1200mm, f4.7 and the best eyepiece I have is a 6mm attached to a 2x Barlow. This should provide 400x magnification.
Ok got it how far can 400x magnification get me?
Is ther a formula that works this out in distance light years AU etc
Thanks Peter
