Astro=Physics scopes.

hmm.. maybe you would like to specify what is your definition of "worth"? depending on your needs, different kinds of scope and different design would be considered "worthy". do you need a beginner start up scope? an imagining scope? or one for collection so you can sell it off at higher value in the future?

Well,i would like one which has certain measuring tools in it. One that is able to measure the distance between stars(doesn't need to be accurate though, just a rough gauge). Thanks haha

Just the distance of the stars? Or would you like the size and mass of the stars?

What is your budget? I think most observatories' measuring equipment costs somewhere $100,000 and above (in USD), excluding the scope.

hmmm measuring the distance between stars.. well if you are talking abt distance in terms of light years.. quite impossible to afford one here i guess.. but if you are talking in terms of arc seconds and degrees maybe you could work out by calculations using the effective FL of ur scope together with a grid reticle projected on an eyepiece

Well,just the distance of stars will do. Which brands do you recommend?

Thanks for the reply haha. I'll try to find out how to use the FL of the scope and a grid reticle to find out the distance between stars.

And when you reach the ability to measure angular distances to around 0.3 arc secs then u are ready to use parallax measurements to tell the actual distances to nearby stars.
