Intes Micro MN-86
In and out of focus star images were textbook concentric rings right out of the box. You`ll need at least a G-11 with 2-21 lb counterweights. Reaching the film plane is easy with a generous 200mm of back focus. It`s a no-frills scope with high end optics. Refractor like images with a 19.7% obstruction. You won`t have to collimate it unless you drop it off the back end of a pick-up truck.

Excellent optically and mechanically. Truly in a completely different league than anything in its aperture range, with the exception of a relative handful of "world-class" 8" APO refractors. Probably the closest thing to an 8" Astro-Physics EDF that most of us will ever get to use.

superbe optique mais des details de fabrication deplaisants comme la fixation
des vis de fixation du chercheur directement dans le tube, la visserie indigne
d'un tel instrument, ce qui explique la note de 9 seulement.
Le notre est arrive totalement decollimate secondaire et primaire !!.
apres recollimation au laser les images sur jupiter et saturne sont superbes. sans doutes les meilleures que j'ai vue dans ce diamtre et meme au dessus
avec oculaires takahashi LE 7.5 nagler 4.8 clave 12mm + barlow tele vue.
en resume il est laid et rustique mais l'otique est fantastique, compter
une heure de mise en temperature avec le ventilateur.

I ordered the 8" M/N OPTICAL SET FROM MARKUS LUDES W. A 1/8 WAVE OPTICAL TEST ASSEMBLED THE KIT THIS LAST MONTH.MY RATING WOULD BE A 10 I HAVE SEEN PLANETARY AND DOUBLE STAR IMAGES THAT ARE THE BEST IV'E EVER SEEN IN ANY TELESCOPE. AND THE STAR TEST IS PRETTY MUCH TEXT BOOK. I LOVE THIS SCOPE.. IT IS NOT THE M/N 86 BUT IT HAS THE 36 MM SECONDARY WHICH COMES IN AT 16.5 % OBSTRUCTION LESS THAN THE M/N 86 WITH NO VIGNETTING APPARANT WITH THIS SYSTEM.

JUST A COUPLE OF CORRECTIONS TO THE RATING I GAVE FOR MY OPTICAL SET PURCHASED FROM APM TELESCOPES. THE OBSTRUCTION IS ACTUALLY 17.5% NOT 16.5 AS I EARLIER STATED. AND A SLIGHT TYPO ON MY E-MAIL ADDRESS.. IT'S MICHAEL.WAGNON2@PSS.BOEING.COM....

I have only recently purchased the MN86 in the last 6 weeks. The star images are pin sharp to the edge of the field of view even with my 40mm pro optic eyepiece. About thirty minutes cool down time with the fan switched on. Use it with D6 mount which is rock steady. Set up time one person is about 20 minutes. And is now supplied with a Goto (UK only ) which makes it a killer telescope. Views of Jupter are breath taking even at this late stage and it being low on the horizon.

Optically superb, with planetary images that are far superior to 10"+ Schmidt Cassegrains. The finder is not particularly good and the focusser should be replaced as it is a bad example of the Crayford design

Probably finest 8" Lunar and Planetary Instrument on the market.
Easily surpasses quality 150mm APO refractors. This is a custom made only telescope and availabilty is very limited. The 8" tube is very solid and it is nestled in a custom made rotating ring carriage that is standard equipment. This makes the scope a pleasure to use at all viewing angles. The tube stays put. Without this carriage the scope would be nearly impossible to handle. The amount of detail seen on Jupiter takes my breath away.
I am strictly a Lunar and Planetary observer and always make drawings when at the eyepiece, while my seeing conditons are usually average at best I can discern very very subtle details within the zones and cloud belts on Jupiter, and I hope to use this instrument one night under diffraction limited skies.

Regarding collimation, I use an Intes Chesire siting tube and i had a Cats- eye collimator
for the primary fine tuning. My seeing conditions rarely if ever allow me and opprotunity to collimate using Polaris, so I count on the Cateyes to get me in the ballpark. This telescope holds collimation and never needs to be recollimaed unless the optics would be removed.

There is no image break down at super high magnifactions and it is limited only by atmospheric seeing. The measured strehl ratio is 97.7 % with a respectable 1/7.2 wavefront @ 555 nm and an on axis resolution of 0.60 arc seconds and an image spot of 7,8 microns (on axis) These are accurate measurements conducted by a third party using an interferometer.

This is a heavy instrument weighing about 35lbs for the tube and 5lbs for the rotating rings and another 5lbs custom made dovetail mounting plate and bracket, all totalled, I would say it weighs in at 45lbs. I could have made the mounting dovetail and bracket less substantial, but I went for a little over kill here.

The MN86 is mounted on an University optics GEM with an Optic-craft 6.6" drive. The setup sits atop a steel homemade pier with heavy duty castors. This is a very sturdy platform for the type of work I do. While the GEM is a giant step backwards in looks, it is extremely stable. Damping is less than 1/2 second, if that. The Optic-craft drive handles the weight of the instrument effortlessly, I can easily roll the scope and mount out of the garage and have it ready to use in less than a minute.
Since all my optical instruments are stored outside under a roof, cool down has never been an issue. Incidently I would never recommend shocking the optics of any telescope by exposing it to 20-30+ temperature variance. This scope deserves to be ready to go at a moments notice.

I would not wish to have to set up this scope on a mount each time
I used it because it is much too large for me to handle in the dark.
If you are an avid observer and have a place to store this scope outside, you will find this to be an excellent instrument
.
I would not recommend this size scope to a casual observer or to the grab and go crowd.

I have been using this scope for over three years now and I have not had the desire to replace it with a better quality scope because I have yet to see anyother scope that is of better optical quality of similar aperature. In truth,
I really ain’t looking too hard either! I have owned a 10” MCT, 10” Newt,
6”, 5” Russian MCTs and a couple of Questars (that’s right once suffered
from cranial-rectal inversion)and I marvelous 5” MN, not to mention
looking through all kinds of super expensive 5-6” APOs, and I am still
convinced this Mak-Newt is superior optically.

My friends use Newtonians, one is an 8” f/8 which I believe comes close optically to the MN86, another has a 10” f/8 that is superior and finally my friend’s 17.5” (f5) Newt which I have witnessed the finest views of Mars, Jupiter, and Saturn. If I ever wished to replace my MN86, my guess is I would go for a high quality 12.5 “ Newtonian.

Hope this helps!
