Maksutov Newtonians .... Presentation coming soon on a separate page

Intes Micro Maksutov Newtonians are all-purpose telescopes with a terrific optical quality. Image sharpness and contrast get close to that of very expensive apochromatic refractors of nearly the same aperture. This makes Maksutov-Newtonians a prime choice for serious planetary observers. .......................................... More about the telescopes' properties

This most compact of all Intes Micro Maksutov Cassegrains already has all the great features of the larger models. In addition it is extremely compact and portable. Good photographical tripods carry this telescope easily. This makes the Alter M500 an ultra-compact all-purpose telescope that is ideally suited for airline travelling.

With the optional focal reducer (0.55x) you turn the Alter M500 into a powerful astronomical telephoto lens for top-grade Deep Sky astro-photography. The focal ratio is reduced to f/5.5 for shorter exposure times and a larger photographical field.

Alter M 603
Aperture 152mm - Focal Length 1500mm

Intes Micro Alter M603 on the Celestron ADM mount - a powerful combination for demanding amateur astronomers.

The Intes Micro Alter M603 is one of the most versatile Maksutov-Cassegrain telescopes that we know. With an aperture of 152mm it has enough light-gathering power for serious deep-sky observing. At the same time the telescope is still extremely compact and portable. It is even generally suited for airline travelling.

Its zero image shift primary mirror focus mechanism allows you to use nearly any accessories you like, including binoviewers for binocular observing, high quality 2" accessories and focal reducers for astronomical imaging.

With the optional focal reducer (0.55x) you turn the Alter M603 into a powerful astronomical telephoto lens for top-grade Deep Sky astro-photography. The focal ratio is reduced to f/5.5 for shorter exposure times and a larger photographical field.

On the image to the left you can see the excellent multi-coating of the meniscus lens - just see how dark the meniscus lens is! You can also see the round openings for the active cooling mechanism. They assist the primary mirror cooling fan in reducing the cool-down time.

Alter M 615
Aperture 152mm - Focal Length 2250mm



Intes Micro Alter M615 on the TS mount Astro-5 - a sturdy and powerful combination - ideal for lunar and planetary observing

The Intes Micro Alter M615 was designed for amateur astronomers looking for a powerful lunar and planetary observing tool. With its long focal ratio of f/15 the secondary mirror obstruction could be kept moderately small.

The largest advantage of this planetary telescope is its compact design. Despite its long focal length the Intes Micro Alter M615 is still very portable and is held with good stability by portable mounts like the TS Astro-5.

With a long focal length 2" wide angle eyepiece, for instance the TS WA 50mm, you get a comfortable true field of view of approx. 1.2°. This even allows some wide-field observations.

For amateurs who want to do Deep-Sky astronomical imaging despite the long focal ratio we recommend the Intes Micro 0.55x reducer. This reducer changes the focal ratio to a faster f/8.35 for shorter exposure times.

The Intes Micro Alter M615 has an integrated cooling fan (see image to the left) that drastically reduces the cool-down time. As a consequence the telescope is ready for use much sooner, a great bonus if you plan to do quick-fire observations of the moon or a planet.

Alter M 703
Aperture 180mm - Focal Length 1800mm




Rear-view of the Intes Micro Alter M703. You can see the cooling fan and the collimation screws



The elaborate internal baffling system effectively eliminates stray light and enhances contrast. You can also see the round openings for the active cooling mechanism. They assist the primary mirror cooling fan in reducing the cool-down time.

The Intes Micro Alter M703 is an excellent, powerful all-purpose telescope with a superb lunar and planetary performance. The telescope can be compared with a very good true apochromat with an aperture of 5". At the same time it collects significantly more light than such an apochromat.

Contrary to popular belief a telescope's contrast will result in a better Deep Sky performance. Dark nebulae can be discerned more easily in front of a pitch black background sky.

With the optional focal reducer (0.55x) you turn the Alter M703 into a powerful astronomical telephoto lens for top-grade Deep Sky astro-photography. The focal ratio is reduced to f/5.5 for shorter exposure times and a larger photographical field.

Alter M 715
Aperture 180mm - Focal Length 2700mm



Intes Micro Alter M 715 on the Celestron ADM mount - a sturdy, powerful and portable combination for serious amateur astronomy

The Intes Micro Alter M715 is a compact, no compromise planetary telescope. It provides clear, detailed, contrasty views of the moon and the planets. More often than not it is the Earth's atmosphere, not the telescope, that limits the resolving power. The secondary mirror obstruction is only 25% - a clear sign that this telescope was optimized for planetary observing.

The big advantage of this telescope is its compact design. Despite its enormous aperture of 180mm and a focal length of 2700mm the telescope is still held sturdily by portable mounts like the TS Astro-5, the Celestron ADM (see image above) or the Celestron Advanced GoTo Mount (CAM).

With a long focal length 2" wide angle eyepiece like the TS WA 50mm you get a comfortable field of view of approx. 1°.

For amateurs who want to do Deep-Sky astronomical imaging despite the long focal ratio we recommend the Intes Micro 0.55x reducer. This reducer changes the focal ratio to a faster f/8.35 for shorter exposure times.

The Intes Micro Alter M715 has an integrated cooling fan (see image to the left) that drastically reduces the cool-down time. As a consequence the telescope is ready for use much sooner, a great bonus if you plan to do quick-fire observations of the moon or a planet. The simple finderscope (image to the left) is replaced by the 90° 8x50 erect image finderscope.

Alter M 806
Aperture 203mm - Focal Length 1200mm


The Intes Micro Alter M806 was designed primarily for astronomical imaging. This is an excellent instrument for serious amateur astronomers looking for a no-compromise, top performance astronomical camera with a very high contrast and a particularly good image sharpness over the full photographical field.

This telescopes fully illuminates a field of approx. 50mm diameter and offers a diffraction limited image over the entire usable field. An integrated field flattening lens on the rear end of the tube achieves this feat. Even large CCD chips can be attached to this telescope without problems.

Focus is achieved by moving the primary mirror. As a result you can use many interesting accessories, like the Celestron Off Axis Guider or a further focal reducer that brings the optical train down to f/3.3, thus allowing for large field astro imaging.

Of course you can also use the Alter M806 visually. The needed adaptors are offered separately.

With the integrated cooling fan the cooldown time of the Alter M806 is drastically reduced. As a consequence the instrument is ready for use much sooner.

Alter M 809
Aperture 203mm - Focal Length 2000mm

The Intes Micro Alter M809 is a premium choice foc amateurs looking for a particularly good contrast and image sharpness. The telescope is still portable, but it requires a sturdy mount with its weight of 13kgs.

With its focal ratio of f/10 the Alter M809 is well suited for nearly all purposes. No matter whether you are into planetary observing or Deep Sky photography, the Alter M809 brings an excellent performance.

On the moon and the planet the Alter M809 can be compared with a true apochromat of 150mm aperture. At the same time it has the much better Deep Sky performance with its much larger light gathering area. Its excellent contrast, e.g. through the elaborate internal baffling system (see image to the left), makes the telescope an even match for somewhat larger Schmidt Cassegrain telescopes (SCTs).

With the optional focal reducer (0.55x) you turn the Alter M809 into a powerful astronomical telephoto lens for top-grade Deep Sky astro-photography. The focal ratio is reduced to f/5.5 for shorter exposure times and a larger photographical field.
