Hi, I recently purchased a neat little 70mm MAK and it came with one eyepiece of 50x magnification as labeled.  The eyepiece used in this scope fits into a special visual back with compression clamping ring and seems to be about 16-17mm in diameter barrel.  This eyepiece also has built in helical focuser built into the eyepiece.   Any help in finding another eyepiece of different magnification would be great.  I have searched around.  It seems some scopes have a 92x  eyepiece as well or in place of the 50x and extra eyepieces are very difficult to find.   I am not opposed to making/modifying something to work with this but I haven't gotten that far yet.   Its a neat little scope and I would like to make it even more useful with an optional eyepiece.  

  Thanks, 
Vaughn

Congrats, looks like you got the Jaegers pedestal for it, as well.  Jaegers sold them for years.  They were school  telescopes originally, I believe.

Thanks for the reply Chuck.  Yeah, I found some great information in a few places online.  I think Edmund sold the pedestal as well.  The seller had a picture of an ad from Edmund in his ad.  The pictures I posted are from the seller's original sale ad.  I am open to more info if anyone has it on these neat/cute little scopes.  I believe there is some info that suggests this scope was also badged under a few other brands as well over the years.   Maybe I need a contact in the Commonwealth of  Poland to find more info and some eyepieces or even accessories.   :)

You may have to make your own eyepieces for it, but I believe the biggest hurdle is that it can't be used with a star diagonal unless you push the focal plane out with a Barlow, if memory serves.

Eyepieces?  How about the box?  Welcome to Kopernik country!

Congratulations on getting the little PZO Mak!

 

Here's an interesting link to an article about the post war reconstruction of the PZO company after their factory was blown up by the retreating German army.  They started digging out and rebuilding while the Germans still occupied the opposite Western bank of the Vistula, nearby.

Here is a recent picture of the historic PZO factory about to be torn down for condominiums!  And the neon sign on top of the building at night.

Just thought I'd load up some pictures of my PZO T50x70 maksutov for future reference.

I think they were marketing these as an inexpensive alternative to a Questar.

Solar viewer with small aperture lens cap, well thought out.

Top of the box, to make sure you know what's inside.  Poland was known for avant-garde graphic design during the time when this telescope was built.

Your little scope is fantastic.  Mine looks the same but I dont have the x92 eyepiece which I would love to find, and I dont have any of the solar viewing apparatus.  Which mount do you have underneath the fork assembly?  looks pretty sturdy.  Ben, where are you located?  I would love to get a hard copy of those instruction sheets or any other literature that came with or that you found for your PZO Mak.  

 

Thanks for sharing, 

Vaughn

I also notice that neither eyepiece matches the optical tube serial (Nr) number.  I wouldnt mind having an X92 eyepiece with non matching serial number for mine.  :)

Yes, I just missed the Goodwill auction of this telescope in the beginning of February and was surprised to see it listed on eBay a month later, it's been a telescope on my bucket list.  The eBay seller had a very fair price did a nice job of cleaning up and packing the scope.  I feel like I made out well.

I'm using a vintage french Gitzo camera tripod to mount this scope.  It's built for use with large format view camera and allows you to mount this little telescope high up, above eye level while standing up, no real need for a diagonal.  

 

I would gladly trade you the x92 eyepiece for a 8mm Carl Zeiss Jena ortho .965, a unicorn for a unicorn!

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.

I have a soft spot for small aperture Maks.  It's just too bad modern offerings aren't built to the same mechanical quality as their cold war era counterparts.  

 

I'm curious how the optics are in the PZO?  Ben, Bagwell care to comment?

Boom, I haven't had clear skies to do any nighttime observing since this cool and cute little scope arrived in the mail.   The daytime views have been short, but look great in the daytime.

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."  Which is something like collecting old telescopes!

Nothing but clouds every evening since I've got the scope, will make a report.
