Last week I bought a cool looking telescope for $30 at a garage sale.  I know absolutely nothing about telescopes and astronomy,  but was just hoping it could be a fun activity with my grandkids.  Well, after some research it appears I scored on my purchase.

Everything seems to be in good working order, but there are no eyepieces nor a diagonal, I think that is the right term.  The motor drive works and I have the original boxes including a page from a newspaper dated in 1972. 

After a research I now know enough to ask some questions.  I don't want to spend a great deal of money for high-end accessories and I to think I want to find and buy the original Unihex turret.  I hadn't planned on selling it, but might consider since it is a collectable.  My primary objective now is to not spend a great deal to get it up and running with adequate and usable optics and then decide what is next.

1) Should I get a diagonal and a few .965 eyepieces?  If so, any recommendations?
2) Should I get an adaptor to go from .965 to 1.25?  If so, any recommendations?
3) Is it worth finding and paying the money for the original Unihex?
4) Anything else I should consider?

Thank you so much....I am really starting flat footed on this one.

Holy cow Don!

  30 bucks for this classic is an amazing find. Serious congratulations are in order.Everyone is different about the eyepieces. You will certainly be able to get a very wide variety in 1.25" though occasionally some very fine used .965s come along. Spend some time here trolling the forums especially refractors and classics. There is a boatload of info available here directly pertaining to your questions. I should have first said welcome but was really stunned by what you found for thirty dollars. You did very very well!

Quick!, buy a lottery ticket to see if your luck still holds!


And offer a word of thanks for being blessed to find such a scope deal.


You're going to have to spend at least another $30 for a couple decent eyepieces.You can look for classic ones or go to telescopewarehouse.com and order his Meade 25mmMA in .965 and a .965 diagonal and barlow.


You will see the occasional Unihex offered at well over $100

Thank for all the comments and advice...all very helpful.  The learning curve has been rather steep, but quite fun.  And thanks for the pix of your Unitron 128.  I wasn't sure what those two plates were on the top tube.  From the pix I am guessing it is how you would watch a solar eclipse...right?


Another Q. After spending too much time watching Youtube videos on how to use the Eq mount, I think I now have a rudimentary idea on how to align it and use it to follow an object.   But I still do not know what and how to use the angled adjustment on RA axis...the one that lowers or raises the scope's angle while in a neutral position?  Would that depend on where I am on planet earth...eg., latitude??  I don't know where it should be set?  


Thanks again....and it is hard to believe I now know what RA stands for...yikes.

Yes, it's for setting your current geographical lattitude

Just for your perspective. These model 128 telescopes in good condition sell in the $600-$900 range. At least that's what I've seen several offered for. In my opinion they are worth the higher price. It's a quality engineered package and will last a lifetime or more if cared for.
