A very rare Tasco find - I got the 16T !!
      #3179304 - 06/24/09 12:00 AM Attachment (113 downloads)

Hello friends,

as posted before, I had the chance to get the white elephant Tasco 16T ! And now : here it is ! ( First garage shots ). This 16T is a very heavy and solid beast, with a marvelous mount and a sturdy and fine made wooden tripod.
Its a 153/1310mm catadioptric system.But don't be shocked : this vintage catadioptric system is of very fine quality !! No comparision with the "modern", cheap Catadioptrics from today ! Its a parabolic mirror, polished with 1/8 wavefront length. The same scope was sold by Mizar as their model CX-150 in the late seventees and early eighties. Sadly the original 15x40 guide scope is lost in the years. The pre-owner added a nice 8x50 finder. The "big" guide scope is not original too. It's a 70/700 mm FH. The rest is all original, even the wooden storage cabinets for scope and mount are present. The hole setup is in very fine condition, only the wooden cabinets and the tripod needs a little refurbishing here and there. There were added a few addons : Eye-pieces from Tasco/Vixen ( circle "V" )K40, K 17,5 , Or 12,5, a 2x barlow, a Tasco panhead camera mount,etc.

The pre-owner bought it around 7 years ago from an old woman ( it was the scope from her husband,and after his death the scope was storaged a few years in a garage and has not seen the stars for years ). The pre-owner told me, that the optics are really fantastic. He had compare the Tasco 16T with his TAL-2M and found the Tasco better on planets !!

Now I will do a little refurbishing the next days and weeks ( but it's not many to do ) and then I will post nicger photos of the setup, if you like.

For me it's a very nice find and I'm very happy with this heavy dinosaur !!

Michael,

Very Nice!

Check out my post on your other thread for a bit more info. I am curious about the optical design.

WOW! Very nice, i never heard of one before but it looks like a high quality build. Good luck with it.

A small scope that gets used often is a better investment than a big scope that stays in the closet.

Unitrons, you spend more time looking at them than you do through them.

Fabulous find Michael,

Can you take close up pics. Especially of the mount. AWESOME. I saw some pics from Galakumas site and thought only in Japan would I see one. That is great congrats.

Outstanding!

As I said in your "warning" post, that's the first one I've seen here. As can be seen from the catalog Steve linked (and which is available from Robert Provin's fine web site), this was one of Tasco's "expensive" instruments.

Now we can see why. That mount alone is a marvelous discovery. The entire kit (even though not completely original) is a dream find. There couldn't have been too many of those beauties sold. I am envious - and don't tell anyone, but I have a soft spot for old reflectors - I just can't afford them.

Congratulations, Michael, on a wonderful acquisition - and thanks for shaking up the establishment here - just a little bit!

Thanks to you all for your nice words !

Well, if I have time I will make more detailed and better photos. This was just a quick shot yesterday evening after "wrapping it out". You can see a wonderfull photo of the Mizar CX-150 ( it's the same scope like the Tasco 16T ) on this site :

http://images.google.de/imgres?imgurl=http://img.blogs.yahoo.co.jp/ybi/1/f7/77/solunarneo/folder/1166371/img_1166371_27173263_0%3F1242567270&imgrefurl=http://blogs.yahoo.co.jp/solunarneo/27173263.html&usg=__9brA7_YS1SK8pSzeW6EaPO0bZi0=&h=1128&w=800&sz=213&hl=de&start=43&um=1&tbnid=IvsSb2q1VHwPXM:&tbnh=150&tbnw=106&prev=/images%3Fq%3DMizar%2BCX-150%26ndsp%3D20%26hl%3Dde%26sa%3DN%26start%3D40%26um%3D1

The optical design is a little bit unusual to common catadiopters. The corrector/barlow lens is placed in front of the little secondary-mirror and NOT in the OAZ.

I have such a mount before ( see my older postings about the Lichtenknecker on Mizar mount ). It's a giant, heavy mount with 180 teeth in RA. On the original parts of this scope you can not find a plastic part ( beside the caps ), it's all metal and wood. The mount feels so strong that I have the feeling, I could a add 2 16T on it !!

This setup was a high-price scope in 1978.
The first owner had paied around 2900 DM for it in 1978 !!
( maybe 1400 $ in 1978 or so..). And I thought, this was very much money in 1978 for a normal worker !!!

I will keep you informed - see you later !

Michael

and as mentioned before :

You can find the original catalog on Robert Provines fantastic site here :

http://geogdata.csun.edu/~voltaire/classics/tasco/tascotel.pdf

There is a nice picture from the 16T

What's the design? Stictly speaking, CATs do not have parabolic mirrors. They have spherical mirrors, with the lens part of the CAT equation being a corrector to counteract the normal spherical aberration. Sure, you can add a built-in Barlow to any scope to extend its focal length, but in my book that does not a CAT make.

Well Rod....see my posting before - the barlow element is placed in front of the secondary mirror. I will not take the scope apart to see it exact. But the information is from the original 1978 Tasco cataloug.

Same as 8v then?...newtonian with barlow

The picture shows the 8v secondary outside of its housing. The housing has a barlow/corrector in front of it.

Hello Steve,

seems to be similar, but the 16T has no glass-plate, but an open tube.

Well..if the weather is fine this afternoon, I will put the scope in the garden and will make a few more photos !

If my english was only better, I would write a "review" about my 16T with many photos, but I think, to read it would be a torture for you all !

From a german friend I got a few more infos about this scope .

About the Tasco 16T he wrote me the following :

" I saw this telescope 1978 in an optic-shop in Köln ( cologne ). It was equipped with a motor drive and it costs 4500 (!!!) DM ( 2200 $...).
I was 12 years old and it was a dream scope for me, but my parents can't afford such a high price telescope in these years. My father was a factory-worker and earned around 1500 DM in a month, so he had to work 3 months to afford this scope ! "

It seems to be that there was a wide price-range !!
The basic-configuration ( wooden tripod, scope, mount, 15x40 finder ) was around 2800 DM ( 1400 $ ?? ), the bigger setup with motor drive and bigger guide-scope and maybe a metal pier ( ?) was around 4500-4800 DM (2200 - 2400 $ ?? )!!

But it's difficult to become exact price-infos from these years !! Maybe some people remember wrong !?

And : in general telescopes in germany are much more expensive than in the USA all the times!

Kind regards, Michael

The optical design is most likely a Bird-Jones which uses a spherical mirror and the barlow like corrector lens to correct for spherical abberation and increase the focal length.

Hey Michael, I'd love to see more pictures of this...

The opportunity to show something really unique & different is what I really like about this forum. In the year or two I've been around CN, I've not seen this scope, so I think that deserves some more detail!

I like CX-150.
When I was a university student, I'd used the telescope,CX-150.
The optical system for the telescope is very wonderful.
At that time, the good quality one was few in a small Cassegrain reflecter, Schmidt Cassegrain.
It was good overwhelmingly compared with them.
It was good in a small mirror because there was a lens just before the secondary mirror .
It is mysterious why the system disappeared.
It comes do not to have to use the stepladder even by 20 inches if the CX-150 system can be applied to Dob.

Hello dear friends,

because of the rainy weather here, I have made a few more pics indoor. I have cleaned the hole scope and refurbished the wooden cabinets.
The hole setup is very heavy and feels like high quality mechanical and optical workmanship. It weighs around 31 kg !
Here is the first new pic :

It shows nearly the original setup with the Tasco Panhead cameraholder like it has been pictured in the original Tasco 1978 catalog ! The only thing, thats not original is the 8x50 finder instead the original 15x40 finder scope.

The setting circles are fine engraved, not printed !
There's no plastic on the mount and the scope. Only the caps, and some mount knobs are from plastic. The other materials are all metall, glass and wood.

This is so far all from me by now. Well, as I said before, I want to write a little article about this scope with more and better photos. But only if you are interested ! I will not boring you !
But : my english is not so perfect - my suggestion is, that I could write an article with photos and save it as a Word-file ( *.doc ). If someone here is willing, I coulkd send my article to him/her for correcting my faults in english text. But I dont know, if its possible, to publish a bigger word-file here in the forum ?
( I guess, for a publishing in the CN-classic-reviews, my article would not good enough...or to boring ). What do you think ?

Kind regards, Michael and thanks for reading this !

Nice Pics. Thanks for sharing. Your english is great Aaron. You should definitely write a review.

I have not seen a mount like that before. Has anyone else seen a mount like that other than on a Tasco?

Aaron.....As you have now witnessed first hand Tasco didn't market too shabby of a product. Your 16T and my 20TE are prime and rare examples of each type of scope. Mike

Mikey , it's allways a pleasure to see your marvelous 20TE - an absolutly dream !! Fantastic !!!!!!

I'm allways wondering, why Tasco had pictured it so small in their 1978 catalog ? I mean, that was the most "professional" telescope from Tasco and it had should
been the eyecatcher in a telescope-catalog !?

Maybe Tasco knows in 1978 soon, that the 20 TE is a rare beast ??
I guess, if you wanted to order a 20TE in 1978, you have long long to wait for it ?...

Kind regards, Michael

Aaron...I can't tell for sure but is your finder mounted in the original rings. Are you going to actively search for a 15x40 finder? Most of these finder types say 12x40 is this what you meant to say? Mike

Now all you need to do is count the number of teeth on the RA wormwheel and get a drive for it . If you are lucky it will have 144 teeth ==> you probably rig up an MT1 motor and clutch on it if you have 144 teeth .

I would guess the Tasco drive for this particular GEM is going to be impossible to find (unless you are VERY LUCKY).

Aaron did anything in the box indicate what year this scope was sold? While not a huge tripod mounted reflector fan this one is very nice and the mount takes the cake for a Tasco,,, Very cool. Kind of a precursor to the Super Polairis...

Hi Clint,

you can find the 16T on Robert Provin's catalog site in the 1978 Tasco catalog. This should be the year, when Tasco releases this telescope. My T16 was bought around 1979 in germany, as the pre-owner had in mind.

I will not activly search for the original 15x40 finder, only if I would find it on a lucky day somewhere on ebay (?), maybe I'll try to get one.

The actual mounted 8x50 finder is a very good one !

The Tasco ( Mizar ) mount has 180 teeth in RA.
As I said before : the Tasco 16T IS the Mizar CX-150.

The wonderfull thing : if you unscrew the barlow element, you get a fast 150/730 mm reflector with sharp images !!!

Kind regards, Michael

Hey Michael, have you had a chance to get your new baby out under the sky?

While I'm sure it will be a pleasure to use, I'll bet I speak for all of us when I say, "Please provide a 1st Light report on that rare instrument!"

Hello dear friends,

after a long search, I have found a picture from the optical design of the Tasco 16T / Mizar CX-150 catadioptric-newton.
This draw I found in a japanese forum :

As I emntioned before : if you remove the barlow-element, you get a fast 150/730 mm newton with razorsharp images !!

Because of the bad weather here, I had only the chance to take a short look at moon yesterday morning. I had very crisp and high quality views, better than in my old Meade 127NT500 newton and better than in my old TAL ( sovietzky ) 150/750 newton !!!
It seems to be an optical high quality barlow/corrector element and the parabolic main mirror seems to be of very good quality !!

This story is getting more and more mysterious : in the 1978 Tasco catalog is written, that the main mirror is a parabolic one. Yesterday I got a manual for the ( identic ? ) Mizar CX-150, and in this manual the mirror is described as a spheric one !! Strange !!
But anyway : the quality of this optics seems to be high class !

Kind regards, Michael

EDIT : I was totally wrong with the mirror and have to excuse me for the wrong rumours I launched here !!

I read the Tasco catalog again and in fact theres with no word mentioned, that the mirror is parabolic ! Maybe I was drunken ?!

In fact it is a spheric mirror, but a good one !!
I saw very good spheric mirrors in the russian reflectors by TAL - for example the TAL 1 ( 110/805 mm and the TAL 2M 150/1200 mm ).
