Tasco 11TR 4.5 inch, 900 mm. Japan, coated optic
Posted 17 June 2011 - 06:32 PM
The tripod is so hard to use that it makes it almost not worth using, eye piece is 20mm and not worth much...but the mirror looks really good. I was wondering if the old scope would be worth fixing up?
Can I put a 2 inch focuser and eye pieces on it.
Can I make a dob base for it? This is my first reflector and I would like to make it work....but not if it would be better to just buy a new scope from orion for $200, and be better off.
Any help would really go a long way for this newbie.
Really, I wanted to get an 8 inch reflector from Orion, but the wife brought this thing home to me....how cool is that? I got to love a woman who bears telescopes for me.

The Tasco 11TR is red....pretty neat looking old scope.
I would think it must be from the 1980s, but I really don't know.
I guess it has been a couple decades since Tasco has put their name on a telescope made in JAPAN.....I think maybe the Japaneese part, is one reason I would like to save it.

If you have not used an equatorial mount before it may or may not be in as bad shape as you suspect - but in any case you could indeed make a dob mount for it if the mount is not salvageable.
As for the focuser - your scope *may* have an old 0.965" sized focuser. You can certainly upgrade that to a 1.25" focuser (I did), but a 2" would be larger then is useful with that scope.
Yes you should be able to post pictures (and they will help!) you just have to keep them under 800 pixels wide and less then 125k file size. When you create a post or reply to a post you have an option to attach a file on the submit-confirmation page.

Changing to a 1.25" focuser is an eye-opener.But you can also find a few new(er) .965 on ebay and probably elsewhere.I like the Meade MA25mm .965 to give old scopes a new view.There are also 15mm Konig,and the .965 barlow will still work with those and probably be better than using the old SR4 for high power.
