>I bought mine second hand and didn't pay much for it ($25 US dollars). It's really not worth much more. Like others have said, the supplied eyepieces aren't much good. Neither is the finder as originally built, but the mirror optics are decent.
>You'll need to do a bit of tweaking to get this scope to work. Here's what you'll need to do to get the 11TR up to decent standards:
>1. Upgrade the focuser from 0.965 to 1.25. That way you can use readily available good eyepieces. Decent 0.965 eyepieces are very hard to find.
>2. Upgrade the finder to 6x30 or replace it with a red eye BB gun type finder. 3. Learn to collimate (align) your optics.
>With decent eyepieces and collimated mirrors, this isn't a bad scope at all. The mount could use some improvement as it is hard to set and keep the proper latitude for polar alignment. However, the mount has wooden legs which help with vibrations.
>Bottom line is, if you can get this scope cheap enough, have good eyepieces, and are prepared to do some tinkering you'll have fun with this vintage telescope. If you are looking to go observing right out of the box, you'll be disappointed.
Finding reasonable quality 0.965" eyepieces can be quite difficult,but if you keep a regular check on ebay,you will eventually find some.
I managed to buy some excellent quality Japanese made 0.965" orthoscopic and kellner eyepieces,which I originally purchased for my thirty year old 90mm f9.3 reflector,made by "Astro" of Tokyo,a great little scope!
The orthos are actually superior to my 1.25" Plossl ep's and way better than the ep's that came with my Skywatcher.
Having been made in Japan,the kellners are also very good.
I purchased an old Lunagrossa/11tr OTA off ebay for only £12,I intend to use it to make a small Dobsonian.The 0.965" focusser is of all metal construction and far superior to the modern plastic 1.25"units that come with 4.5" scopes these days.
It came with the mounting sleeve,but without a finder,so I added a Meade 6x30 finder and bracket,which I only paid £5 off ebay for(cost so far £17)
I,ve already tested the scopes optics,by temporarily mounting it on my Skywatcher 130's EQ2 mount.Once I had properly collimated it,it performed really well and I had some excellent views.
I must admit to having a liking for retro equipment!

>I couldn't vote for the mount,as I only purcased an OTA,to make a Dob with and because I used to have the Later Tasco 302012 114/900mm model,which was an excellent telescope.
>After mounting it on an EQ2 mount and collimating it,the views were very good.
>Replace 5x24 finder and cheapy ep's and you'll have a very good telescope.
My final vote is for the OTA only,which is why I have rated it slightly higher than I did the 302012.Had it come with the mount the result would have most likely been equal.

I have a Tasco 11TR sm D114mm F-900mm Telescope but it missing the small adjustable optic. Where do I purchase this?

Someone gave me this Telescope but its missing the focuser and I guess the eyepiece. Where do I find these items to get it up and running?
Thanks Robert. email@example.com
