Thanks Bill, yes has been a while but I started up the astro engine a few weeks back. I would LOL but that was when I had bought and owned my MK66, sold it around 2005/6 to a fellow out in your neck of the woods, it was 1/6th wave according to the ITE lab test report but the optics were extremely smooth. It is in no way scientific but from memory that scope today would compare to my Orion 150, it did take two samples from Orion to get this one but I was a first adopter on them bringing back the new version of the 150 and I kind of had the feeling that the first scopes mirror had a little flop inside the tube but I never had taken it apart. I did check this one and no mirror flop or focus shift, this is why I am very reluctant in selling this sample. That MK66 was built like a tank I kind of wish I never sold it but I bought my first C9.25 after that scope but although the optics were ok the mechanical issues were a real pain. I've owned way too many scope and not enough time, LOL.

Just for kicks, here's the Roddier test of an Orion rebadge of the MK-67. The test was done using a 632nm laser source so I'll leave it as an exercise for the reader to calculate the PV and RMS values (and hence Strehl ratio) in green (555nm) but I'll tell you it's very good.

Interesting - the impact is clearly visible - Intes scopes have literally vanished from the market for used scopes. So everyone is keeping them...

 

FWIW I've received a reply from Costruzioni Ottiche Zen to the effect that they no longer make finish OTA's - only optical sets (mirror + corrector). For sizes larger than 180mm they're they only one left.

 Lack of parts is a concern for sure. If one could be found an OTA with broken optics could be cannibalized. I'm going to start calling calling mine Valdimir to get on the good side of you know who. The only time  Valdimir had to be serviced was when  the  dew shield shredding dovetail bar popped a rivet. OPT put a Celestron one on it, they cleaned and re-lubed the focuser too which is much smoother now.  David

 Lack of parts is a concern for sure.

Spare parts simply don't exist for Intes scopes. There isn't an Intes scope on the interwebs - not even a busted one in bits on eBay.

 

Note also the Intes website hasn't been updated for several years which does indicate they are well and truly defunct for commercial scopes.

 

As for mine, the 9" optical sets were a special made by Intes for Santel which folded more than 10 years ago, and I have never found hints of another scope like this one outside Russia. 

 

Looking back over the last few years it appears Intes had lost interest in building finished OTAs some years ago and only APM was brave enough to take on building OTAs to order with Intes optical sets. But even that has dried up now.

 

So... yes I'd suggest they are now firmly "classic" status, to be looked after carefully.

 

They are pretty simple, to the extent that mechanical issues can be  fixed at reasonable  cost - I'm having a new backend made for mine in order to replace the original focusser with a decent modern one, and will open the OTA up at some point to add more dovetail plates and a nice handle or two.

 

But damage the optics... you're out of luck.

I have 3 scopes from this firm, a 24" dob, a 16" and a 6" Apo. All of them have exquisite optics. They are handcrafted in Venice, Italy.

Speaking of mak manufacturers that have been and gone it seems there’s another one - what is known about Construzione Ottiche Zen ? http://www.costruzioniottichezen.com

And "Simaks" which are Mak-Cassegrains at f5.6 which is highly unusual...
But we go off topic...

Seems to be raining intes maks in the last month...

An MN56 sold, oldie but apparently pristine optics, a mint APM/Wirth 8” f/6, MN106 still for sale and I know of a very good MN61 for sale elsewhere.

I have recently added an Mk 67 and an MN56 to my collection. Main reason was I got the pair from different people for less than $1K combined (and my LOMO 95 was lonely). Mk67 is almost mint and yes I hate the focuser (the JMI focuser on my early MK 65 was better). Ordered an adapter from Starlight so I can put one of my FT focusers on it. As for the MN56 it has a loose secondary mount. Something I have dealt with in the past in scopes that came directly from APM to us at Hands On Optics. Not sure what I might do to its focuser.

My Intes Mak 603 Deluxe has been getting a lot of use of late. Mainly because it fits well on a Skywatcher star discovery mount. It is around the recommended limit of this mount but I have had fun using it in the past month.It creaks a bit in altitude but for the price it has a lot of good features. They are very easy to use.

 

We are doing a road trip in a motor home over Summer and I think this set up might come along for the ride.

 

My IM603 has a good functional focuser. The images are really nice and cooldown is not really an issue here in NZ in November.

 

I agree with the convention a 6 inch 33% CO scope is similar to a 100 mm apo on Planets. The extra resolution and extra aperture excels on deep sky targets. With a 1520 mm focal length this scope delivers just over a degree with a 32 mm TV Plossl eyepiece.

The mass of the bare ota is 4.8 kg, add a diagonal, eyepiece and red dot finder and it comes to 5.3 kg. Add a dew shield and the total is 5.5 kg.

It is a shame these scopes are no longer made. I also have a 703 which is about 6.5 kg for the bare ota. I mount this on an Ioptron ZEQ25 and an old AP600E mount.

An Intes Micro MN 66 at Markarian Fine Optics in Vancouver

Thanks for the heads up! I just purchased it. grin.gif

 

It will likely replace my very nice quality, 6" achro

Just curious

 

Will I get substantial vignetting with 72 degree eyepieces (Delos) with the MN66 and its 21% obstruction secondary?

Tyson no, not in the Delos as the largest is 17mm so the field stop is comparable to that in my SSW 14 (82 degree field).

In say a 2” 38mm 70 degree eyepiece yes you would.

I plan to use my 40 pentax xl and 27mm pan as well. Maybe the 32 plossl but likely skip over that for the pan

Congratulations! It's one of the finest telescopes I have ever owned. Routinely outperforms 5" apochromatic refractors.

I was told it is like a 5.5 apo! I will be my TEC wanna be.

 

I feel that picking up these mak Newts are special, especially consider the topic of this thread.

 

Mine comes with a feathertouch and rotating rings. But the tube has some cosmetic paint-loss issues. I'm not too concerned though, corrector looks brand new.

I have been really perplexed by the lack of Intes equipment on the used market. It's kind of like they have become like Quantums and only rarely come up for sale.

Reaching thermal equilibrium is important with these scopes. Once equilibrated, these are insanely sharp instruments. One of the best moon scopes I have ever used.

I'll put it in a soft carrying case and let it sit outside for an hour prior.

 It's just sad considering how good the scopes are. You not be seeing my IM715D  in the classifieds. David
