  • Sky-Watcher Starlux 190MN

    The Sky-Watcher Starlux 190MN is a 190mm Maksutov-Newtonian with a 1000mm focal length (f/5.3), just what astrophotographers and serious visual observers have been looking for. It has a 2" dual-speed Crayford focuser and a 64mm secondary mirror, and the tube weighs 12.5 kg.

    The 190mm f/5.3 Maksutov-Newtonian

    The Mak-Newtonian design provides large-aperture apochromatic performance with exceptional field correction in a compact, affordable package, and yields a sharper and more contrasty image than a similarly sized Schmidt-Newtonian. It is an excellent visual performer too.

    The highest practical power is 380x, and the telescope is recommended for deep-sky observing.

    Schott Glass and a 64mm Secondary

    Sky-Watcher's Maksutov-Newtonians use Schott glass for the positive front crown element in the objective. Schott is the recognized world leader in glass for precision optical lens systems.

    A large 64mm secondary mirror increases field illumination for larger CCDs. The secondary obstruction is 34% by diameter and 11% by area. The lenses are fully multi-coated, and the mirrors carry Sky-Watcher's Radiant Aluminum Quartz (RAQ) coatings.

    Field Correction and Camera Connection

    The design gives exceptional field correction. Whether a corrector or flattener is needed for imaging is not stated.

    A 2" T-ring adapter and a 1.25" eyepiece adapter are included.

    A Precision 2" Dual-Speed Crayford Focuser

    Focus is by a mechanically ultra-smooth, backlash-free, precision 2" Crayford focuser assembly with fine and ultra-fine focusing adjustments, standard on the Starlux 190MN.

    • 2" drawtube: takes 2" accessories; the included 1.25" adapter takes 1.25" eyepieces.

    A 12.5 kg Steel Tube

    The tube is rolled steel, powder-coated reflective gloss black with a gold fleck accent; the front and back cells are cast aluminum. The tube weighs 12.5 kg and measures 19.5 cm x 93.5 cm.

    Tube rings and a V-style dovetail bar are included, with a right-angle correct-image 8x50 finder.

    Mounting

    The tube weighs 12.5 kg and comes with rings on a V-style dovetail bar. The AZ-EQ6 Pro and EQ6 Pro mounts are related products; choose a mount whose payload rating covers the tube, camera and accessories.

    Solar Safety

    Never point the telescope or its finder at the Sun without a proper solar filter securely covering the front of the telescope: looking at the Sun through it will cause permanent eye damage.

  • What mount does it need?

    The tube weighs 12.5 kg and comes with rings on a V-style dovetail bar. The AZ-EQ6 Pro and EQ6 Pro mounts are related products; choose a mount whose payload rating covers the tube, camera and accessories.

    Is it good for visual observing?

    The Mak-Newtonian is an excellent visual performer too, with a highest practical power of 380x.

    How well corrected is the field?

    The Mak-Newtonian design gives large-aperture apochromatic performance with exceptional field correction. Whether a corrector or flattener is needed for imaging is not stated.

    How does it compare with a Schmidt-Newtonian?

    The Mak-Newtonian yields a sharper and more contrasty image than a similarly sized Schmidt-Newtonian.

    What is the Schott glass used for?

    Sky-Watcher's Maksutov-Newtonians use Schott glass for the positive front crown element in the objective. Schott is the recognized world leader in glass for precision optical lens systems.

    What size is the secondary mirror?

    64mm. It increases field illumination for larger CCDs; the obstruction is 34% by diameter and 11% by area.

    What is included with the Starlux 190MN OTA?

    The tube, an 8x50 right-angle correct-image finderscope, tube rings, a V-style dovetail bar, a 2" T-ring adapter and a 1.25" eyepiece adapter.

    What is it best suited to?

    It is recommended for deep-sky observing, and the Mak-Newtonian is just what astrophotographers and serious visual observers have been looking for.

    How big and heavy is the tube?

    It weighs 12.5 kg and measures 19.5 cm x 93.5 cm, in rolled steel with cast aluminum front and back cells.

    What is the focuser on the Starlux 190MN?

    A mechanically ultra-smooth, backlash-free, precision 2" Crayford focuser with fine and ultra-fine focusing adjustments.

    What finder is included?

    An 8x50 finder, a right-angle correct-image finderscope.

    Can I use 2" eyepieces with the Starlux 190MN?

    Yes. The 2" focuser takes 2" eyepieces, and a 1.25" adapter is included.
