Wow, a very interesting webpage, thanks Dave for the link.  I used Google Translate to be able to understand the writing and can say that Alexey Petsyk has that soulfulness that a  Russian literary critic once wrote about, "Russian literature has a bad tradition. Russian literature is devoted to the description of unsuccessful love affairs."


I definitely see that with Tolstoy, Chekhov, Pasternak, but I’m having a hard time working that into my understanding of Dostoyevsky. I guess because of Raskolnikov’s relationships with the women in his life! lol.gif

If you want to see the progenitor of this scope check out this site. Scroll down and you will see that the PZO is a near replica of an original scope by Maksutov himself.

Oh wow, that is a great find - it includes some good pics of the little baby scope that appears in S&T Gleanings Bulletin C.

While we are on the topic of Maksutov telescopes!   Bart Fried and professor James Hedberg of City College with the school's never used 8" Fecker Maksutov telescope circa 1947.  Bart and I, of the New York City auxlliary squadron of the Antique Telescope Society, have been working with the college to get this scope used for the first time!  This is one of the first Maksutov telescopes to be made in the USA.

Wow, that is one gorgeous telescope! Knowing Feckers, I'll bet the outfit weighs a literal ton. Thanks for posting this, Ben!

Here's an earlier version of the PZO Maksutov with a hammer tone finish and different knobs.

I love that 1968 diagram from Stellafane. Made myself a copy to keep! Thanks :)

Was that made to be a competitor of the DDR Zeiss Telementor or was the Telementor only distributed to schools in the DDR? I didn’t think they allowed competition in the Eastern Bloc back then.

The PZO Maksutov is very similar to the Maksutov telescopes built for the Soviet schools.  The PZO Maksutov telescopes were built for the Polish schools and the Zeiss Telementors were built for East German schools.  But some of the production of these telescopes went for export for hard western currency in short supply behind the Iron Curtain.  We know from the movie "The Death of Stalin" that the Soviet Politburo enjoyed a good Hollywood cowboy movie, 35mm prints are pricey!      

 

Here's the Soviet Maksutov school telescope, love to find one of these.  I believe it was made by the makers of TAL telescopes, the Novosibirsk Instrument-Making Plant, compare the logo on the lens cap of a TAL-65 with the build data plate on the Maksutov.

A self portrait by D.D. Maksutov from the late 1940s titled  “A shortened author of shortened telescopes”.  Another artist in optics!

Took the PZO T50x70 out this morning for the first time.  Didn't really have enough time to let the scope cool down, so I will leave the optics report for another time.  I'm enamored by this little telescope.

Almost got one of those when Jaegers had them in the catalog. Still would like to get one at some point.

Some more PZO Maksutov information.  An inspection certificate and some literature from a British importer.

Some more reference images, this time of an earlier version, 1950s or 1960s, of the PZO maksutov with a hammertone paint job.  Seems like many of these were created for an economic program called "1000 Schools for the Millennium of Poland" which happened in 1966.

I had one of these here in England in the early 70’s, my first ‘real’ scope. Bought with my paper round money

rigged it up with a gun sight Dial sight mechanism on an engineers angle block to make an equatorial mount.

 

lovely little scope, superbly sharp and contrasty. Jupiter’s red spot was an easy catch. 
moon views were great, tack sharp and high contrast, helped by the very fine eyepieces.

spent many a happy hour staring into it.

 

disappeared during my parents house move when I went away to sea, still miss that little scope.

That's a great memory Andy.  We all have some great memories of our early astronomy experiences.  Do you happen to remember the eyepieces you had?  I am still looking for some eyepieces to work with mine. 

Thanks, 

Vaughn

HI Vaughn, 

 

mine came with the 50x and the 90x. I remember at the time looking for something more powerful and drawing a blank.

the 90x really wasn't pushing the scope.

The eyepieces were works of art, real watchmaker scale stuff. Kelners iirc.

Thanks for the info.  Yeah I have a 50x but I dont have the 90x.    I would like to find the 90x at least or maybe figure out something else that may work.  The compression tube is an odd size as im sure you remember.

Might be worth an ask on a Polish astronomy site or check their local small ads sites.

 

search for ‘PZO Okular’

 

don't be worried about asking around ‘over there’, most Poles speak good English.
