Tasco 11RT

#1

Post by LDW47 »

Has any one owned or used a Tasco Model 11RT scope from the mid 80's ? I have a chance to buy one like new, incl an eq mount, for about $100 C but before I decide I thought I had better ask.

I think it is a good price for like new 11TR. The scope has a good following and some are still used for observing. Just be aware that it comes with 0.965" focuser and included Huygens EPs are not good.

Hi LDW47,

For that price, why not? As Bigzmey said, a decent scope, but you'll want a better focuser for sure.

I have an old Tasco built to the same specs, and even with the spherical mirror, it puts up a really sharp image, especially at f/7.8. Easy to collimate as well.

I bought my Tasco for the same price, $100, and have never regretted it. I did get rid of the EQ mount and built a Dob base for it. Here's a blurb I wrote for a member on here with all the specs for that if you're interested.

My scope was manufactured by Towa; Tasco is just a rebrand of that. I also have a Towa 3" and a Tasco 3TE; both 3" mirrors and really great views for their size.

The scope you're looking at is probably made by Tsanzutsu, given the era it was built and the tube color.

So, how do you tell? Look at the label near the focuser. If you see a circle with a capital T in it, it's a Towa. If there's a diamond shape with a capital D in the middle, it's a Tsanzutsu. If it's neither, I'd like to hear about that :lol:

I've heard as much bad and also good about that manufacturer, as well as Towa; though that's mostly about their refractors it seems. But in my experience, the Towa reflectors are quite good, and I've heard the same about the Tsanzutsu brand. Anything after the mid-eighties was really a joke...

It's so grab and go, and works wonderfully well with a 1.25" focuser and some decent eyepieces. It would be a fun project... ;)

All the best,
Mark

I also had a 11TE which I put on a dobs base was OK but not great , I landed up giving it away ,but was great fun building it
Cant seem to insert a picture at the moment
There is no adaptor for the focuser so to use modern eyepieces one has to change the focuser

How does one insert an image now ?when I click the insert image it just places 'image' instead of taking me to the options?
