Subject: What is a 'NOVA by Bushnell' telescope?
|
Bushnell's web site has been less than forthcoming with info and while
(via a Google search) I can see old eBay auctions I have yet to come
across any real info on this thing the roommate picked up at a yard
sale.
Being a less than experience amateur myself I am loath to 'fix'
anything and make things worse but I suppose there is some fine tuning
it could go through to tighten it up.
Here is what I know so far:
- It's a (used) refractor type telescope.
- It came w/ a single view lens; RK=20mm
-- Printed on the side was the following:
700mm Focal length
76mm Objective lens (f/9.2)
Designed by Bushnell
Manufactured in China
The last gives me _some_ pause but it's 'a bird in the hand' situation
so I'm calling it my Starter Scope and going from here.
Any tips and/or experiences would be appreciated.

This is all the information you need, really. It's a 76mm (3 inch)
refractor with a focal length of 700mm. Divide your the objective
length by your eyepiece focal length and you get magnification - in
this case 35x. That magnification is best for larger objects like open
and globular clusters, but not so great for planets, although you'd be
able to make out Saturn's ring and Jupiter's moons.
Is there anything you can do to make it better? Well, if the metal
part of the eyepieces are 1.25" instead of 0.96", then you can improve
things greatly with the purchase of one or two Plossl eyepieces for
not a lot of money. Should you decide that you like this hobby enough
to invest more money, you can use those eyepieces in other, better
telescopes too.
The other problem is going to be the mount. It's probably not going to
be your friend at high magnification. But if you decide you want to
replace it, you may as well get a whole new telescope, quite
honestly. :) Drop by your local telescope store and ask for their
advice. After using this one for a bit, you'll have a better idea
about what you want.

This is probably a Newtonian reflector that is outwardly similar to
the 3-inch Orion Spaceprobe. If you only paid $10 or $20 for it, and
if no important parts are missing, then you might have gotten a good
deal. You will get 35x with the 20mm eyepiece, which a good basic
magnification for this scope.
One concern is collimation of the optics, although a 3-inch f/9 should
be rather forgiving of slight misalignments.
If you Google: Newtonian Collimation or: Collimating
Newtonian , you should find adequate instructions. You can
probably get by with the simplest method which involves making a
"peephole" out of an old 35mm film canister to fit into the focuser
and then first making sure that the large primary mirror appears
centered in the small diagonal mirror and -then-verifying that the
diagonal appears centered in the primary.

It's a trasco scope under a newer name after trasco folded.

This one line should make you run away very fast.
