The Tasco Brothers, 9VR and 10VR refractors, 60mm/300mm and 80mm/400mm respectively, both made in Japan by Vixen. Both of mine have excellent optics and came with quality accessories including a pair of Vixen Orthoscopic eyepieces.

These are the smallest, shortest F-ratio vintage Tascos I have.

Very cool! How does the 10VR perform? I've never seen one of those. Are they much harder to find? Thanks for showing them.

I don't know how rare they are compared to the 9VR. Two of them showed up on EBay before Christmas and I got this one. It comes with an aluminum case (the 9VR has a vinyl one), but otherwise the same basic package with 2 orthos, altaz head, photo adapter, etc. The objective has a slight rattle to it. I can't see anything to tighten down though and it looked in good condition. Turns out the rattle doesn't affect it at all. It has a great star test with a well defined bull's eye pattern both in and out of focus. It's a fast ach, so there's color around Sirius and Venus. Jupiter is a bit washed out, however it gives a surprisingly sharp view of the Moon. It's good for deep space with a nice wide field of view, and enough light grasp to catch the Leo Triplet in a dark enough sky (two of them at least). It's also great for splitting multiple stars, Castor is very pretty at high power. The Orthos are excellent quality but 7mm doesn't really bring out the power potential of this scope. Fortunately I have some quality eyepieces down to 5mm. I havn't tried the Barlow yet but it's well made, the barrel is heavy and made of metal instead of plastic. I'd say if you can find one of these go for it. Mine's definately a keeper.

Really cool.

I had no idea Tasco had such products.
Do you know what year(s) they were sold?

How is the Cromatic Aberration?

I checked Robert Provin's site and it appears the latest Tasco Cataloge is from 1978.

We need to find one from the late 80s and 90s.

Mark, I don't know too much about these, when they were made and what they cost new. I'll welcome any such info that anyone else can give. I know that Tasco sold some later incarnations of the 9VR, not made in Japan, and with plactic bodies I think. The model number was 99 or 999.

They both have the typical CA of fast achromats, with a little bit more in the 80mm as you might expect. But both my samples have otherwise excellent optics, sharp and contrasty with no discernable astigmatism or coma, and the views are very nice. I would love to know the Strehl numbers of these two. I'm not an expert but I suspect my 10VR has much better than 1/4 wave optics. Same with the 9VR. I don't know how many Tasco sold of these two but I don't see nearly as many up for sale as the typical 60mm achromats they've sold out of Japan.

The Tasco/Vixen 10VR and 9VR are from the Halley's comet era around 1984-86*. The Tasco 99VR and 999VR are diamond "Z" marked from the same era. I have a 10VR and a 99VR. The Vixen product is much nicer than the U.R./"Tanzutsu"/diamond "Z"

*Google Books shows the 10VR in a 1984 Popular Science ad from "The Sharper Image" for $399+19.50 shipping. The description is mostly correct but a short red varipower 'scope is pictured

David,

Here is a picture of mine. PM me a contact and I can send you the 4 pages for this scope. You can see a teaser of the papers in the case top pocket in the photo. These papers are dated 1983.
The focuser draw tube is large enough for 1.25" eyepieces directly and I replaced the .965 ep retaining ring with a standard Vixen 1.25" then I added a 1.25" to .965" adapter for the original accessories. I also kept the original .965" ep ring for originality. A quality 1.25" eyepiece, without a vignetting hybrid adapter, really makes this shine, including helping with the achronic abberations. I had it in the window for some time as a day spotter.

Hi David, Here's mine. Not quite brothers, more like cousins. :grin: Tasco 10VR 80 mm and Celestron CO-62 62mm. Both Vixen and very good optics. Makes a great wide field and solar scope. Matter of fact the CO-62 is currently on loan to a friend's 6th and 7th grade science class to study sun spots with a 1000 Oaks solar filter. :)

Sharper Image might have been priced high, but thats $870 in todays cash. :shocked:

Neil, I actually like the styrofoam in the 9VR's case better than the cell foam that comes with the 10VR, mine at least is poorly made and makes it difficult to store and retrieve the parts. If you look closely at my photos you'll see I have a 1.25" Vixen adapter on my 9VR. Ortho's are nice eyepieces but not the best design choice for these fast refractors. Modern 1.25" plossls work great. I'll be sending a PM soon.

Hi Scott, nice pair! I've also done white light solar with my 9VR with good results. CA is not much of an issue with solar viewing.

David E.,

I enjoy collecting and using my telescopes but my focus currently will be getting my Interferometer working and building a Ronchi tester. I have been talking about this for a couple years now but one of the reason's I have amassed my scopes is to quantitatively test them and see how good the figure of their optics are.

Mark, hope you get that going soon, I'm sure there will be a lot of people very interested in the results of such a project! :D

Hello to all,

I read your posts with interest and thought I could add a couple of things.
The 10VR was also released by Vixen under the name "Planet 80S". Another evolution of this one and 10VR was a model known in Europe as the "Halley 70". The improvement, despite being a 70 (actual 72mm)/400mm, was that an X-Y fine adjustment was added on a large ring, something models like the 9VR (for this one, a fine adjustment mount was provided in the case) and 10VR did not have.
I don't know if the "Halley 70" was sold in North America (was sold in Asia and Europe). It would be interesting to know.
Here are 2 pictures of the Vixen "Halley 70" (mine came with a grey case with no window). Second picture is mine on a Vixen mini-mount which is motorized.

That's a nice refractor, thanks for sharing photos of it. I don't think that scope was sold in the US but I could be wrong. Tasco, as far as I know, only sold the 60mm and 80mm models. The 60mm was originally made by Vixen, but later versions were made by Tanzutzu.

You are very welcome!
I know that Tasco 9VR and 10VR (made by Vixen) were sold in France in the mid 80's but were replaced by the "Halley 70" when becoming available. They are scopes to keep for life.

Three of them (Halley 70) are available for sale in France currently (prices range from 220 to 300 Euros). Another solution for you would be the Vixen 70S guidescope (some were sold on Astromart).
