For now i have a EQ3-2 mount with both axis driven and a 90mm refractor.
I'm
just a poor student so i don't have a lot of money and i'm wondering
what
telescope would fit on my mount so i won't have to buy a new mount? I
doesn't have to be a refractor because they are expensive. Is it really
less
expensive to buy a telescope without mount and eyepieces or not? What
would
you recommend?
Let me tell you again that i don't have a big budget like some
others....
Let's say about 600$.
It is worth remembering that there are a lot of 'parts' to whether a
particular scope will work acceptably on a given mount. For instance,
taking four 5" scopes, a 5" refractor, an SCT, a Newtonian, and a
Maksutov. The refractor will probably have the shortest focal length
(longer focal length shows up the faults of a mount more), but will weigh
perhaps twice what any of the others weigh. The Maksutov, and SCT, will be
the lightest scopes, but the Maksutov will probably have the longest focal
length. The SCT will typically have a fairly long focal length too. The
Newtonian will probably (depending on the tube design), weigh slightly
more than the SCT, but will have a shorter focal length.
I'd look for a second hand small SCT (the C5, is an excellent little
scope), or about a f/5 to f/6 6" Newtonian.
Another poster has suggested the MN56. This is a lovely scope, but might
be pushing the weight a little (it is a fairly heavy assembly). However if
you can find somebody who has tries a scope of this weight on the mount,
and can verify it'd be OK, this is a very nice unit.
It is less expensive to buy just the scope 'OTA', but generally not as
much less than the complete 'assembly' price, as the mount costs.
