It is such a tragedy that the great Russian Maks are not being produced. I have an Intes that is such a wonderful telescope. A decade or so ago there were several Russian companies still making them. Did they just disappear because of the limited demand? 
Stellar Optical Corp’s web site still comes up, but it is dated.  No?

I agree.  I picked up a Russian-made Orion Argonaut Mak-Cass at auction a few years ago.  It's a 6" f/10 and gives wonderful planetary views.  I did a side-by-side comparison with a Skywatcher 120ED doublet looking at Jupiter, and the views were nearly identical. There may have been just a hint of more contrast with the refractor but it was really hard to see any difference.

Agreed.  Love the Russian Maks.  Cooldown can be annoying on mak cass's with the primary baffle, but the mak newts are truly a thing of beauty.

See https://www.cloudyni...nd-intes-micro/

Post #2 has a link to an older thread with the details. Between having no business sense, over 30 years failing to update the cosmetics of the OTA, and the loss of key staff... The final nail in the coffin was probably the cost of the blanks for the correctors compared to whatever Synta is doing.

By the time their scopes were better appreciated they were long gone.

 

Here’s some exquisite Intes glass...

I had a Russian Intes Maksutov about a dozen years ago which was excellent. I now have a Synta Maksutov which is equally excellent but smaller. The Synta Mak is very well built but the Russian Intes Maks were built like tanks and required heavier duty mounts because of their weight which is why I sold my Russian Mak and just stuck with my lighter and easier to handle Synta 90mm Maksutov. Either way, I'm still enjoying great views of the moon, planets and brighter multiple stars!! If one can obtain a used Russian Mak and can handle their extra weight, they should by all means grab it!!

The Russians could produce some very nice things.

I would say this is the case. TAL is barely there, Intes has some partnership with dealer in japan and sells through some mak from them..but it's rare. The only russian scope I have is a lomo mini mak, but it's built beautifully.

AT least they still make lenses..

I picked up an Intes MK91, recently, in like-new condition. I’ll be putting it up against my TEC160ED. At 228mm and f/13.5, I’m curious how it will perform compared to a top-notch 6” refractor.

I suspect planetary will be much of the same, when seeing cooperates for the larger scope. DSO's going to the Intes

I love my Russian Maks! Still have my Intes (Orion) MK67 (Argonaut) Mak-Cass, my Intes Micro MN56 Mak-Newt, and my LOMO Astele 95 Mak-Cass.  Before that I owned Intes MK65 and MK66, and LOMO Astele 133.5 Mak-Casses. Helped that I worked for a dealer for all three.

Pics of the Santel !

 

Personally I'd expect the MK91 will win that contest easily if (a) the comparisons are done at equal magnification (b) the MK91 is insulated and perfectly collimated, and © the seeing is half decent... but I'll suggest you'll have to wait till its planet season to really see it stretch its legs.

 

The reason I say that is that is while I had an MK91 some years ago, it was pretty routine to take it to 300X most nights and 500X was not uncommon. It also handled average seeing deceptively well; often others would be grumbling about the seeing while I'm thinking "huh ? looks OK by me ...".  

 

In particular there was a night of exceptional seeing with Saturn high in the sky (80 degrees) and at 600X it was possible to see the Encke division in the rings - the rings looked like they had grooves, like a vinyl record. With several present it took us a while to understand and really take in what we could see, as a CPC1100 and 12" LX200 alongside couldn't match it for details. Encke is comfortably beyond any 6" scope/eyepiece/observer combination.

 

Another interesting test is how many of Saturns moons can be seen, though the MK91 should win that easily thanks to the aperture.

 

It was that MK91 that convinced me to acquire my current big mak, which likewise does not disappoint.

I hope you're right. I've been thinking about upgrading my TEC160 with a TEC180. The 160 is an absolute pleasure, but my mount can easily handle a 180. So why not? But that's an expensive upgrade for just 20mm of additional aperture. So I thought I'd give one of these Russian Maks a chance.

 

I live in SoCal so the acclimation isn't a big deal. I'll still wrap it with insulation, though. 

 

Clouds tonight...

The Mak should win in all categories except FOV and Thermals.

Going back around 2005 I owned a IM M603 plus at the same time a Skywatcher 120ED, the views on planetary were nit and tuck but if we had a night of good seeing the mac would spank the 120ED as far as observing at higher powers but one you got to lunar the 120ED was left in the dust. The 120ED had a wider FOV but that was it, color correction was very good on that scope but the M603 had none, I really should have had my head examined why I sold the 603 but the next scope was a C9.25 in which back then I had a bad case of aperture fever. MY older brother owns three Intes scopes a MK67 and IM M703 and M500, he has hinted that he might sell me his MK67, I now own an Orion late sample 150 mac which is not bad at all but those Intes scopes were always a tad better in the optics, some of the China made scope are decent but overall smoothness and optical quality still goes to those Russian mad mac's.

I certainly didn’t buy it for its FOV. smile.gif This is strictly for lunar, planetary, and doubles. 

 

Yes, thermal is my only concern. I really like being able to mount the TEC, plop an eyepiece in and have at it. There’s no time like the present.

In the case of Intes/Intes Micro, scopes disappeared because Putin ordered all their commercial production to cease.

 

He redirected their production to satisfy military & scientific demand.frown.gif

Narrow field of view is an asset for a telescope that performs well for planets.

Thermals: A simple insulation wrap solves that problem.

Disagree as any 6" F7 Apo can do both!

 

The thermal insulation trick works for some but not everyone.  It is IMO location dependent.

I built a removable insulating cover for my MK-66. That way I can cool it down faster without the cover and put it on just before observing.

However, I still have the feeling that I have some turbulence left in most cases  scratchhead2.gif . When I manage to properly cool it, it performs very well smile.gif .

Perhaps you are missing the point by trying to cool it down ?

Do I? I never thought of not cooling the scope down. Thanks for the hint, anyway, I will try that.
