They are getting harder to find ! Which company I wonder will take the 6 to 10” Mak Cass and Mak newt challenge on and produce scopes of similar quality ???

Well you didn't specify about price or availability (waited almost 20 years for mine), but....

I’m also on the list Paul !! BUT I’ve just ordered a 12 “f9 Maksutov rumak from Romano zen in Italy 😀 the f 9 is a compromise I know but it was too good to pass it’s has a CO of 31% I had a zen 10” Mak for a few weeks from a friend superb optics , so when it arrives il post some pics and do a report 👍👍

I'm too old to wait 20 years for AP to deliver, so ordered the last of the APM/Wirth 10" maks f/12.5 with Intes glass, a while ago.

 

It arrived last week, and I had first light briefly in rather poor seeing. Despite the seeing it was evident this is an absolutely stunning scope, optically. Matthias Wirth's baffling is very impressive on the moon, and is stunningly clear and contrasty to the extent I expect some of the refractor types will turn a pale shade of green.

 

Hopefully the weather will improve this weekend.

 

My trusty Santel MK91 won't be neglected - it has a new owner champing at the bit.

Stuart, 

 

Is Mr. Zen still making optical tubes or did you source the tube through another company?

hi George
I was lucky this was the last tube he had ! I know at f9 it’s a compromise but his optics are as good as Intes Micro scopes I’ve onwned , and still own a 10” Mak newt, the tube is well made I’m having a carbon fibre dew shield made currently, Zen still makes optical sets at a very good price and there a few Italian based company’s who will tube them for you ( a future project) I will test the scope as soon as I get some spare time !

Apologies I've been on holiday since the day after it arrived, now that I'm home its raining (as one might expect) - at least the farmers are appreciating the benefit of my attempt to break the drought here :)

 

A quartet of exoticats, from left:

 

- 50mm f/12 MikroMak (Jim Riffle)

- 150mm f/15 Intes M615

- 228mm f/13.5 Santel MK91

- 250mm f/12.5 APM/Wirth

I'm especially fascinated by the 50mm micro Mak. Pray tell us more about it.

Jim Riffle (CN:Jim Riffle) made a small number of the MikroMaks and sold them earlier this year - they're gone from his website so I assume all sold now.

Although primarily a desk ornament sitting on a miniature equatorial mount, complete with RA worm drive and dec tangent arm, the scope does actually work and is equipped with a miniature star diagonal (prism) and a boxed set of 3 eyepieces.

 

Optically does actually work quite well - it's f/12, the corrector is AR coated and the image is quite reasonable. I think the glass was possibly left over from a production run of something else, probably the Celestron 50mm spotter.

If a few of us wanted this, would he do another run.


BTW, is it a "Solidcat" type?


The Solidcat refers to a design from the 70s where the correctors back surface is silvered to make it the primary mirror.

You’d have to ask Jim but I don’t think you’d like the price. These were one offs not a commercial product.

No it’s a typical Gregory mak... - secondary is an aluminised spot on the inside of the corrector - and it has moving mirror focussing (!) with a tiny micrometer screw at the rear.

Collimation isn’t adjustable so it is limited by Jim’s machining tolerances. It’s a nice effort by an amateur machinist, though not comparable to a questar.

I have purchased an MN66, Carbon Fiber MN76, and now an MN86 is on it's way.

 

I do love these scopes.  I also have a SkyWatcher 190MN that is my workhorse for imaging.

 

Learning to align these properly has been a great learning experience and the rewards are fantastic flat field images with pinpoint stars!

 

Just need to add an MN74 or MN84 to the list and I will be good to go.

Hello, I'm the owner of Intes MK91, that from astromart posted here earlier. Can You write me something about history of mk91, how many there were produced?, what can be quality of optics(i haven't interferometric test report)? and so on...I verry like this telescope, it has sharp pointy stars to the Edge, but require some thime to termal stabilize. here are picture:

Hi DominRZS,

 

“Thermal stabilisation” can be achieved in the time to set up the scope if you apply insulation around the OTA. Reducing the rate at which the OTA cools reduces the thermal gradient between the tube and the central baffle, sufficiently to stop the thermal plume you'd otherwise see. Secondly it reduces the rate the corrector cools, so dewing is also reduced. Extending out the front, it enhances the baffling against stray light.

 

Two low cost DIY solutions I tried (both effective) are Coreflute, or cannibalising an old car sunshade; wrap around the OTA and secure with some Velcro. https://www.cloudyni...-tube-currents/

 

Another issue may be which focuser yours has; imho the JMI original was woeful and I upgraded mine https://www.cloudyni...der-steeltrack/
 

A few details of Santel have been posted before; these days they are making observatory scopes not amateur gear.

 

But I traded mine for this...

Got to spend a night with an MN76 under dark skies once, and was very impressed with it. Wish I’d have bought one while they were still readily available.

Owned an MN 61 and now an MN 76 Deluxe Intes Micro. For only an inch of aperture more is much better.


I also have an M809 8" f/10 Alter

Discovered something new today - Intes made 7” and 10” f/3 Maksutov astrographs with a Mangin mirror. The 7” was designated M73. Some issues to overcome with adapters for modern digital cameras (used by stupid bourgeois westerners) but nonetheless they sound promising...

Couple of old links here:

https://www.cloudyni...-f3-astrograph/

https://www.cloudyni...astrograph-m73/

If only they stayed in production, the 7” would be very sweet with modern CMOS cameras. Anyone seen or have one ?

What about the Tak E-180 (F2.8) or Sharpstar 200mm (F3.2)

I had two of them, An Intes MK66 and an Intes MN61 (the Orion Argonaut Version).

Both were excellent scopes and delivered extra sharp images. The MN61 had more contrast than the MK66.
