It's always fun to visit Dave Trott's house and come away with something new. lol.gif   As I was heading out the door with some eyepieces and Goto things, Dave offered me this Tal Alcor 65mm f/7.7 reflector kit.  I was blown away by the tank-like build quality and for what has to be a kid's telescope, I was thinking if you can carry it outside setup, you're old enough to use it. grin.gif

 

Everything seems to be heavy walled steel.  Specs I got from Steve M M's thread from 2015 here:

 

https://www.cloudyni...or#entry7709655

 

It appears complete, but no manual.  Also I don't have the nifty spec documents on the inside of the lid as this is later version and has styro inserts.  Not sure how long I will have it, but I am amazed at quality of optics.  Tack sharp.  A 15mm eyepiece for 33X and then the barlow and sliding extension to give 88X and 133X.  Love the slo-mo controls.

 

And you pretty much have to be sitting down to use it comfortably as an adult.

One of my neighbors in MD had one of those. Like most Soviet things everything is built out of scrapped T-34 tanks from WWII.lol.gif

Exactly!  So, if anyone decides to make an extra tube column, I'll take one too smile.gif

 

I actually sold the one from 2015 to a person in IA who begged me to sell it to them as the scope had family significance to them.  Then, during the ebay sale last year, I bought another one that was new in box, but needed a bit of help from Chuck  :)   Now it truly is NIB.

So I noticed the pic with the cell back showing.  It shows N2017  89-4

 

No way this is made in 2017, but April 89 makes more sense to me.  Steve M M said his was '88 with wood blocking in case and mine is Styrofoam and possibly 89.  Does that make sense or does the 89-4 have nothing to do with date of manufacture?

I love the ‘telementor’ (school scope) look of them. They certainly seem to have been made in the spirit of the T1 with that heavy tube, uber robust construction, and excellent optics.

My current Tal Alcor has 1994 on the case and 1994 on the contents slip

So I think this says 4-89 is a good date for mine.  However does yours have Styrofoam or wooden block separators.  If mine were earlier you probably should have Styrofoam.  And does N2017 make mine number 17 of one series, 2017 of one series or is yours a new and different series.  Can't believe there weren't a ton of these made and still in Russia.

This will probably makes things more confusing, but my 1988 and 1994 are both wood inserts.  No styro.

Interesting.  Your cell back plate is much simpler than mine.  Yet rest of pieces look very similar.

I will have to wait until I get home to get to my photos, but mine has the date on the nameplate on the box and has styrofoam inserts too .

I think you will be stunned with the views you get through it too.

I too was thinking Telementor. Love the industrial professional institutional look. 

 

Cool scopes guys! waytogo.gif

Here it is with an extra pier section installed, for use while standing (my preferred posture while observing).  I have two of these, but the base is missing on one.  I borrow the extra pier section from the incomplete one.

One of them came perfectly collimated, the other required some tweaking, so I had to remove that sticky silver goop from the collimation screws.

Chuck,  what are your dates on the cell back/case labels and are your cases wooden blocked or Styrofoam vs. date?  Thanks for sharing that.

Stew, I'm at work and both cases are at home, but I remember that one has wood inserts, and the other a very hard styrofoam.  One of each.  I'll check the dates at my first opportunity and let you know.

Looks cool Chuck but doesn’t that long, skinny post vibrate like a tuning fork?

I too was gonna say that it looks really cool, and also really easy to tip over with just a very slight nudge.

The Russians knew their engineering.  The pier is very thick-wall aluminum.  The resonance frequency must be very low because I detect virtually no shaking

The tri-stand base is cast iron, and heavy.  That said, the footprint really is too small for safe use in the dark when that tall.  If anyone else was out with me, I'd omit the third pier section.

Stew, I can't dig them out until the weekend, they are buried.  But I did find pics of the case labels. This is interesting.  Both same year, but vasty seperated serial numbers.  I believe the lower number is the one with the wood inserts so possibly 1994 was the transitional year?

Chuck, I think it makes sense that the N7568 is the Styrofoam and the N0152 is wooden.  That would match Steve M M's with low serial slightly before yours as wood and later, and the N7568 a long time after mine ('89) N2017.  So Styrofoam case was earlier.  Let's see if that fits. 

 

bremms, could you tell us serial and case type of yours and date of manufacture?

I believe the serial numbers may have started again each year as my styrofoam is n0110 1996

If that is the case then I wonder if there aren't two different manufacturing facilities where one put out styrofoam and the other wood. undecided.gif

It may just be that the telescopes took off in popularity so it was no  longer cost effective to do the wood inserts.
