Very nice.  I don't have one, but I have always admired them.  I have had the 6" an 5" Intes MNs though and they were simply superlative.

Why does the secondary have a protruding mount?  Instead of just a silvered spot.   Is it collimatible?

The Intes Micro is a variant of the Maksutov that is called the Rumak (Rutten-Maksutov designed by Harrie Rutten.)

 

The silver inexpensive silver spot secondary means that you cannot easily have a different radius of curvature on the secondary mirror than on the rear of the corrector.  This is desirable because it allows you to correct for some aberrations that would normally be present in an MCT at f/15.

 

The US company Questar is reported to have cut the secondary mirror into a recess on the rear of the meniscus so that it could have a different radius of curvature than the rear of the Meniscus, but the Rutten approach is probably much easier to make (and of course we know that Questar scopes are hugely expensive, but that probably is just because it is a very boutique kind of offering). 

 

The Rumak design simply puts the secondary on a separate surface so it can be aspherized easily to correct for aberrations that would otherwise be present in the Gregory design. 

 

These are some of the best telescopes money can buy.

Yes its a Rumak or Sigler type Mak. Allows creating shorter faster focal ratios similar to SCTs, which require a different curve than just the back of the corrector.
Myself I have an MN56 (Intes Micro), Mk-67 (Intes), and a LOMO Astele 95.

Some shots of my three IM Maks. 815, 603 and 703. With an 8 inch Meade SCT in the top and middle shots for scale.

Shot 1 L to R 815, Meade, 603, shot two Meade and 703, shot 3 703.

 

I probably use the 603 the most these days, partly because of it's low mass which fits on  simple goto. The 603 and 703 are f-10 Rumaks and the 815 is an f-15.

Here is my Intes Micro MN66 with a feathertouch.  

 

It is a bit inconvenient on this style of mount because I cannot sit down, so I will be building a dob base on it.

I have made the perfect dew shield out of a yoga mat.  Bonus, no painting or sewing required! 

 

The outside diameter of the tube and focuser just barely fits around the elastic strap to hold it together!!! 

 

I have put about 7-8" of extension past the corrector.

I have a similar dew shield and my wife made me the same elastic straps as you have - great minds think alike smile.gif

Nice scopes!

 

One thing I learned real quick with my Intes scopes was that, while a noble idea, those stock baffled dew shield worked just horribly.  The baffles would allow heat from the corrector and tube to pool inside the shield and spill over the baffles into the light path, giving the scope a terrible case of the thermals.   Not only that, they are H-E-A-V-Y, adding weight up front, exactly where you don't want it.  An odd mistake for such an otherwise, well though out product.

And some more.  

 

Trying to figure out where I parked the photos of the MN55, MN56, M615, M500 (a dynamite little scope)

 

Do you think I like them or what?  grin.gif

What rings fit the MN66 tube assembly? I was thinking about getting another set just for mounting finders/accessories on.

I still own the APM MW MN86 and the Intes MN76, both very nice instruments.
