I've owned Meade and Sky-Watcher's 7" f/15 Maks and each has its own little quirks. Both were fantastic with Baader's Hyperion Zoom! Perhaps one day I'll get a chance to experience if the 'all-business' Intes-version solves the issues I've had with other brands...

This YT channel is outstanding. I've learned a great deal from it and this has allowed me to enjoy night sky viewing 10X more than I used to in my early days. Thanks much, Ed! Cheers.

As always a fun, informative and entertaining overview. Well done Ed. I've owned several of these. Yes, Intes scopes are the Russian T34 tanks of the telescope world. No frills or even fancy powder coats. But fantastic optics once properly collimated and cooled. But, ahh, that's just it. Regarding collimation, yes, you have control over both the primary and secondary mirror alignments. A nice feature, but this means you also have two ways of really messing up the collimation. Every single one of mine I got real "cheap" because the owners had completely screwed up collimation. After about a half hour or so of tedious, iterative, adjustments, everything was fine...and sharp! Regarding cooling. REFLECTIX!! Many of us have found that adding a couple of layers (yes, two as a single layer is not enough) of Reflectix to our Maks and SCTs tubes (and backplates) does wonders to stabilize the thermal environment of the tube and optics. The difference in thermal performance envelope using the stuff can be striking. No more fair weather friends. It's sooooo easy to work with and install/remove. And it's CHEAP! Actually a video on the use of Reflectix or similar insulation might be very useful and of much interest to your fans. Again, well done sir and thanks! Jeff

jeffblazey Hi, Do you know of a tried and trusted method of collimating these scopes. I have an Alter m603 (6” Mak Cass) that’s out of collimation. It’s not out too much, but having two mirrors to adjust, I don’t want to make things worse. Now that the weather’s starting to pick up here in the U.K. I want to start using it. Thank you.

Great review Ed. I learned a lot as always. Keep up the great work!

Ed, I simply LOVE your content, THANK YOU

I always look forward to your videos. Thank you Mr Ting, keep up the good work.

I have a couple of 6” Intes Rumak. One has a fixed primary mirror, the other has a moveable primary. The nice thing is the movable mirror is on a scissor cantilever so no mirror flop. I put a reducer on it to image larger galaxies. Got great images of black eye, sunflower, pinwheel, and the like. Without you can go deeper. Both give great visual observing of planets. I have been waiting for a 7” but none have popped up. Even the 6” gives great refractor-like view of the moon. I think these can go head to head with Questar.

Excellent presentation and very informative. I use my Binotron 27 in my Orion 7” Mak. Tons of backfocus allows focal reduction via the power switch on the Binotron. This makes the scope more versatile and deepsky views are enhanced. I’m willing to send you a model to review. Anyway great job Ed.

New Ed Ting video always puts smile on my face, keep doing what you do!

First time I came across Intes and Intes micros was during the early naughties in the Optical Vision brochures. Have never observed through one of those telescopes but a friend of mine showed me a pair of Russian binoculars from the 40's 50's and couldn't believe the clarity of what I was seeing through them. The image was so crisp it was like you were standing right next to what you were viewing. Not even my ED binoculars could compare to those Russian bins for clarity and the Russian bins were about coming on 75 - 80 yrs old. There is alot to be said for Russian optics.

I have a 100 year old zeiss 6x30 binocular. Other than then the lack of coatings which didn't exist back in 1923, they are amazing. But at night I prefer my 1970s single coated japanese 7x35 wide angle. Even the the zeiss has no distortion over its 50degree field and the outer part of the 7x35 is astigmatic, they are considerably brighter even though they have the same exit pupil. During the day the zeiss kills them

The one image on astrobin, uses a reducer for f10. There are elongated stars in the corners of the image! For £3500 scope and plus expensive reducer, demonstrates this design is for planets or moon close ups. A DK cassegrain could do this at a tenth of the price. But nobody makes one. DIY like I did.

I have the Intes MK67 and I leave it outside for a couple of hours with a bin bag pegged over it . You could leave it in your car for protection from the elements, Ed is correct, they take a lot of cooling, I thought about putting it in a chest freezer for 20 mins but my wife insists it's for food!

TEC used to sell an 8 inch f/15 Mak, also Russian. Heckuva scope, heavy though and took forever to cool down. Great for the big Mars opposition 20 years ago. I think TEC just sells high end refractors now. That's Telescope Engineering Co., Golden, Colorado.

Gorgeous telescope.

Just found your channel; love it. I have a lot of viewing to do. I'm thinking about returning to the hobby after a 40+ year hiatus. I used to grind and build my own, about a dozen scopes from 4.25-12.5"; loved the wide-field scopes I made. Have none of that now, so have started looking. The hobby is so different with the computerization, the proliferation of refractors and the seeming emphasis on photography. I'm trying to figure out what will be best for me now; suburban skies, humid air, not great seeing generally although on the best of nights I've caught the Milky Way. With my older eyes, I think I'll have to be content with the planets, Messier catalog and similar NGC objects. I've wondered about Maks, Questars were a dream of sorts back when; as a primary scope it doesn't sound like a fit now, although there is a Mak-Newt out there that might be about right (have you done a review of those?). Thanks for the channel, I'll be eating it up for the next few weeks at least.

My local astronomy store has a new one in stock (UK). I've always had a soft spot for Maksutov telescopes and will no doubt get another to add to my 12" dobsonian and 102 apo.

I had one of the earlier Intes 6 inch Mak-Cassegrains and it compared well to my 7 inch Questar. They did a good job. There have been some remarkable if somewhat obscure large Mak-Casses over the years, like the Aries unit of the 1980s.

I saw several craterlets in your shot of Plato!

I have a couple of the Meade 7”LX200 and LX50. I took the plates out and put them on standard eq mounts. Very good. My Favorite for double stars is my RuMak Intes MK66 and 67. Don’t have the 715 yet…😊

Mak's are awesome niche scopes, I had a 150 and it threw up awesome planetary and lunar views, as planetary imagers they are fantastic. If I ever saw that Intes for sale I would drive a thousand miles for it, not even kidding.

Hi Ed, I think I've found one of these close by, so I'll continue my program of acquiring telescopes you recommend :).

Also bringing any scope in from the cold outside to a heated property will cause a lot of moisture on the whole scope, a hairdryer works well here.

Do we always have to be perverts and see cunnilingus even while watching telescopes, with a 4 year old?

Thanks for another great review,Ed. I used to own an Intes Alter 7" Mak (Rumak variant, I think) and that thing was not as good as the one you reviewed. Cool down was a major problem and optically, it wasn't as sharp as I'd hope it would be. Definitely not a good beginner's scope, at least in the 7" size.

With cameras making lucky imaging possible with more dso's, and more pixels sizes to get the correct f-ratio combinations, giant mak's will make a comeback at some point. Some of these recent cameras have such low read noise that exposure length is becoming less relevant. And the main benefit of lucky imaging is breaking through the arcsecond limitations of the sky by taking rapid exposures. The only thing limiting a pristine mak's optics is the sky.

I have a Skywatcher Skymax 127 Maksutov which I bought in pristine as new condition second hand with a load of accessories, including a dew shield and Bahtinov mask for the princely sum of £200. I can only imagine the difference in viewing though!

I use it on my Skywatcher AZ GTi for quick and easy setup. Would like to get a lymax cooler for it sometime.

I didn't catch it in your list of 7" Maks, but Celestron is now selling one, but I don't see it sold as an OTA only, just paired with the AVX. Since it's Celestron, then it's going to be the Synta-made version, the same as the SkyWatcher and the old Orion variant. I know someone who fixes CGE mounts and has a few he strips for parts. If you're having trouble with yours, I can get you his contact info.

My only remaining must-obtanium scope - a 7" Mak. My heart is set on the 7" Meade but the 180mm Skywatcher/Orion Synta scope beckons as well. Would love to see a comparo that included the latter. It has an excellent reputation. Thanks!

I have a couple of Meade 7”. One had a bad secondary spot and I ended up having to resurface it and get it recoated, now it is hard to get these spots redone. From Cloudy Nights forums, i found unlike the Intes of course, the Meade 7” seems to have an aspheric mirror matched to the corrector plate. They are not swappable between scopes of the same model, they are paired from the pool of plates and mirrors.

Fazergazer Hi there, I also own two Meade 7” Maks. One of them I got cheap some time back. The one I got cheap, never seems to give the same image quality as the other one. Both have had the counter weights removed. You state that the Meade’s have matched optics that are not swappable. I’m wondering if the meniscus had been put back in a different position from that at the factory. Do you know if so, would it, or could it affect the image quality? Many thanks

Twenty years or so ago I would look at all the adds throughout Sky& Telescope and Astronomy mags and seriously looked into the Intes series. They were very competitively priced. Of course some were hit and miss. JMR

Best used with a big furry hat.

Other special design is the Field - Maksutov wich uses a sub-aperture corrector lens group in front of the secondary mirror. Open tube, large obstruction. The Vixen VMC series scopes use that design. I owned a VMC110L and a VMC200L earlier. The smaller one is quite soft, the secondary is not adjustable, plus it has an integrated flip mirror which is also not collimable. Compact, might be good for sidewalk astronomy or travel, but a 70mm f/6 refractor performs much better in a similar weight and it is much sturdier. The VMC200L can be excellent if everything works fine (the temperature is right, the scope is in the right position), but it is unreliable, the main problem is it's primary mirror holder which basically stress the mirror or let the mirror flop around, practically impossible to find the good setting point between these states. Also the 6mm (!) thick secondary spiders can cause insanely large diffraction spikes around brighter objects, forget Venus on low magnification (

My 10 inch Dob has better resolution, but is less sharp and less or similar contrast. Would a Mak bridge the gap? If so, what is a reasonable size?

Be nice if someone made an astro-photography camera with laser pointers that could shoot down Starlink satellites.

Why not put the scope in a old refrigerator or freezer for a few hours set to about the predicted out side temperature , that way it would nearly be the same temperature and would not need cool down time . I have been thinking about buying one of these scopes maybe if the price is low enough .

The Maks in the five to seven inch range seem to be most popular. But didn't the Russians also market a high quality 8 inch Mak? These I've heard of or read about but never had opportunity to try!

arongyorffy Here in the U.K. back in the early 2000’s there were quite a few Russian telescopes of various designs on the market. The high end manufacturer’s were Intes and Intes Micro (two different manufacturers) I also seem to remember a company called Yelna. At the ‘lower’ end of the market was a manufacturer called Tal. There were quite a variety of designs on offer, such as Maks, Mak Newts, Mak Cass, Newts, and refractors. Possibly due to the apo explosion at around the same time, a few of these Russian gems started popping up on the used markets now and then. I have owned and looked through a few Russian scopes from high end Maks down to a humble 112mm Newtonian reflector. I have yet to find a bad one optically. Even the 112mm Newt really surprised me with it’s optical quality. They are out there, just not as common as they once were.

INTES, we can't get it new any more. Only the small remaining in a used market. In my experiences, every INTES had excellent optics, despite most of the owner tuned worse from factory tuned condition. It's the shame. Without interferometers or optic tools, you should not disassemble them. If you did, it will never be the proper condition. In a way, Makustov is the far distant triplets. Even a tiny bit of misaligning will yield to degrade the performances as a triplet of refractors. Whole tube is the lens itself.
