Vintage Sears Discoverer Telescopes
      #999579 - 06/14/06 05:57 PM

I have owned several vintage Sears Discoverer refractor telescopes. Of especial interest is their extremely rare Model #6345 sold only during 1970-72. This instrument looks like a very large version of Tasco's popular 60mm f/17 Model No. 7TE-5 equatorial, or a smaller version of Tasco's rare 108mm f/15 Model No. 20TE Observatory.

I have had two Model #6345 90mm f/15.5 Sears scopes; each one was superbly constructed with very good optics. There is a 40mm guidescope and 30mm viewfinder mounted on the main tube. The only complaint in the design is the excessive weight of the optical tube assembly and the equatorial mounting head, which are not adequately supported by the proper pier or tripod. Even though the wooden tripod is sturdy, it cannot accommodate the weight that it must support. One 90mm telescope that I had I remounted on a solid Pentax pier to correct this fault.

I am interested in knowing how many of our members actually own or have seen one of these. I have been trying to get the exact production figure, which must be buried somewhere in Sears' archives. My best guess is that less than 500 of these were ever made and sold in the United States. They are extremely collectable and can realize $1000 in today's marketplace. They originally sold for $500, and the inventory was finally sold off in 1972 in their catalogues at a sale price of $300. Post any info this website. John W. Siple.

I KNOW I didn't get one- that was the same year I got my first reflector scope. Dang!

Hi John!
Wow , now THAT is a very interesting story. Can you please get some pictures taken of it and post them here on this forum? I am SURE all of us Sears refractor buffs would love to see what that unit looks like!

I hope to publish a small two or three page article about the rare Sears Discoverer 90mm f/15.5 refractor in our local astronomy club newsletter. It will be found in the article "A SAMPLING OF TELESCOPES FOR THE AMATEUR ASTRONOMER--PART 17," slated for possible publication in the next September or October 2006 issue. It will feature a brief history of the scope, attachments and accessories, photographs, and some observations. I do have the very rare owner's manual, an unusually complete document of about thirty pages with extremely detailed diagrams to the last nut and bolt, etc.

For those of you who are not familiar with Tasco's vintage No. 7TE-5 Solarama 2.4-inch f/17 refractor, please type in www.rca-omsi.org/ Select Newsletter at the top of the webpage. From the archived back issues view the May 2006 issue of THE ROSETTE GAZETTE for an article entitled "A LUNAR GALLERY." The Sears 90mm looks like a HUGE version of that scope, minus the Optica b/c pier of course.

I have also had the honor of owning a vintage Tasco Model No. 20TE Observatory 4.25" f/14.8 pier-mounted refractor, and a virtually identical Southern Precision Instruments 108mm. A picture of me standing next to my old Tasco 20TE can be found in the article VINTAGE TASCO TELESCOPES--PART 2. This article is found in the archived (pdf format) May 2004 issue of the same newsletter. The Sears 90mm refractor is almost as big as that scope, except for the pier (the Sears has a wooden tripod, somewhat of larger dimension than Tasco's Model No. 10TE/15TE Solarama 76.2mm). It should be noted that the same equatorial head used on the Sears 90mm was also placed on Optica b/c's rare 6" Newtonian of the 1960s, and on Lafayette Radio's "Arcturus" 3" f/12 refractor (see Part 7 in my series about THAT scope). Cordially, John W. Siple.

John
for your interest I have a 60mm f20 (1200mm)Astro Optical Industries refractor - Images are text book perfect !!
If I am not mistaken I think the Tasco 2.4 inch (60mm) F17 was also made by Astro

John,

Wow! I enjoyed reading your articles on THE ROSETTE GAZETTE. I bookmarked that website for continued reading enjoyment. That is an excellent publication!

Well, I beleive I got one for Christmas in 1970 - it was a 90mm, f15 Sears scope on a GEM. I don't believe my parents paid $500 - perhaps $300. Was it packed in a wooden case with brass corner guards? I owned it until a few years ago when Huricane Floyd submerged it in my basement. After I rescued it, I noticed that over the years and several moves the lens had developed a chip about 1/2 the size of dime along the edge. I had some amazing views with that scope,including one memorable night where I spent at least an hour and a half on my back viewing the most incredibly detailed spiral galaxy I have ever seen. I hope it was a different model because I'd hate to think something special....lets just say it's history!

John,

I have a friend who owns one of those Sears 90mm scopes, I believe... he had ordered the 76mm version but Sears was out of it at the time and substituted the 90mm for it, if I'm not mistaken. He says he'll never get rid of it... I can point you to him for additional information, if you need it.

Len,

Will do. I should see him in a couple of weeks, and will probably email him before that.
