Skywatcher Explorer MN 190mm f/5.3 - Maksutov Newtonian Telescope OTA

Skywatcher Maksutov-Newtonian Telescope MN 190/1000

The Maksutow-Newtonian is a true alternative to conventional Newtonian telescopes with coma correctors. The telescope provides large aperture, high speed and excellent field correction. That are exactly the requirements for a dream telescope for astrophotography. Furthermore, the Maksutov-Newtonian also offers a very good visual performance with an image quality close to an apochromatic refractor.

The advantages and features at a glance:

Very good field correction and sharpness on the axis due to the combination of spherical primary mirror and a meniscus lens at the front side.

Well suited for DSLR and astro cameras up to full-frame size sensor.

No coma correction necessary anymore.

The secondary mirror is attached directly to the meniscus lens, there are no annoying diffraction effects from the spider.

Ventilation slots next to the lens at the front speed up cooling down of the telecope.

With only approx. 12 kg weight, the Maksutov-Newtonian is carried even by transportable mounts like the AVX from Celestron or the H-EQ5 SynScan from Skywatcher. We recommend the EQ6 mount for astrophotography.

The primary mirror is made of Pyrex, the glass of the meniscus lens is made by the world-renowned manufacturer SCHOTT.

The primary mirror is oversized to ensure better illumination for photography.

A closed system. as known from the refractor, prevents air turbulence in the tube (tube seeing)

An elaborate system of internal baffles and a high-quality coating of the meniscus lens increase the contrast of the image.

Photographic results with the Mak Newtonian

Crescent Nebula with the Mak Newton 190/1000mm - by Wolfi Ransburg

Only two days after full moon, I have pointed the 190 mm Mak Newtonian to NGC 6888, basically just for testing field sharpness and image characteristics of the Maksutov Newtonian. The instrument immediately convinced with good sharpness over the entire field, so I exposed the Crescent Nebula 6x15 minutes, despite that the moon had risen in the meantime.

Imaging camera was the ATIK 4000 with 23 mm sensor diagonal. The Mak Newtonian provides excellently sharp stars over the entire format.




Helix Nebula with the Mak Newtonian 190/1000mm - by Wolfi Ransburg

Only in the Bavarian foothills of the Alps the Mak Newtonian achieves its full potential. High speed and good field correction allow imaging even fine structures in nebulae. I exposed a total of three hours through the Mak Newtonian. The telescope has maintaned sharpness optimally all the time.

Jupiter with the Skywatcher 190mm Maksutov Newtonian

Photographer Markus Langlotz

The 190/1000mm Maksutov Newtonian is not just a very good optics for nebulae and galaxies, it also shows excellent performance on moon and planets, as the jupiter image from Markus Langlotz proves. We sicerely congratulate to this outstanding result.

1.: M51
Camera: Canon 1100Da
Exposures: 42 frames with 3 minutes each, 2.1 hours altogether, ISO 3200.
Autoguiding using Lacerta MGEN and TSOAG9EOS-Off-Axis-Guider for EOS.
Focusing using Bahtinov maks.
Stacking with Deep Sky Stacker; astrometry with Astroart; slight increase in color saturation using IrfanView.
One can see a large number of more distant galaxies in the field. M51 shows already the tidal bridge in the region of the companion NGC5195.

Camera: ZWO ASI 178MC color camera.
Photograph from 30.12.2016, 6:51 CEST using Firecapture; AVI sequence of 78.7s duration, 19 FPS, 50.5 ms exposure time per frame.
20% of the frames averaged with Autostakkert2.
Wavelet filtering and RGB alignment using Registax.
Here the surface of Jupiter already shows many details, in particular the Great Red Spot. To the east, one can see the moons Io and Europa.

Best regards, also to the team, and many thanks again for the good advice!
