Cassegrains

Looking for Celestron Cassegrain Telescopes? We stock a great range online and ship from Sydney to anywhere in Australia or New Zealand. A Cassegrain style telescope looks like a short stubby refractor where light goes in one end, and you look out the other. Unlike a refractor which uses a lens at the front of the telescope to collect light, a Cassegrain uses a mirror at the bottom of to reflect light up the tube to bounce off a curved mirror through the hole in the main mirror. You observe or attach a camera at the rear of the telescope. In telescopes like SCT (Schmidt-Cassegrain Telescope) or Maksutov the glass lens at the front of the telescope is used to make corrects to the quality of the image and doesn't actually concentrate light like a refractor would.

The Sky-Watcher VIRTUOSO GTi 127/1500 Maksutov-Cassegrain Tabletop Dobsonian is a fully automatic telescope ideal for beginners and those who want to get straight to observing. Aligning the mount takes mere minutes with the “Bright Object” alignment mode, and the computerised SynScan system is the ultimate upgrade that allows automatic pointing and tracking of more than 42,000 object in the sky! This means less time spent finding a faint nebula or a distant planet and more time to enjoy observing. Astronomy has never been so easy!

The Maksutov-Cassegrain is a compact and powerful optical design that combines a front meniscus lens and two mirrors. The optical tube is closed by the front meniscus, keeping the mirrors protected from atmospheric agents such as humidity, dust and pollution. The tube is short but the focal length is long allowing high magnification with the standard eyepieces. With maximum practical magnification of 256x , this Sky-Watcher Telescope will reveal details in Saturn’s rings, Jupiter’s bands, the Martian polar ice caps, and the phases of Venus and the moon.

The VIRTUOSO GTi Dobsonian Mount – Wi-Fi-controllable with iOS and Android and compatible with syncs hand controller, allowing it for smooth tracking and alignment. Use Wi-Fi to control the telescope wirelessly with your mobile device; smartphone or tablet.

Sky-Watcher 127mm/1500mm Skymax 127 Maksutov-Cassegrain OTA

The Sky-Watcher 127/1500 Skymax 127 Maksutov-Cassegrain OTA is a compact and powerful optical design that combines a front meniscus lens and two mirrors. As the optical tube is closed by the meniscus, the mirrors are protected from atmospheric agents such as humidity, dust and pollution that over the years degrade the reflective coating of the mirrors. The tube is compact but the focal length is long allowing high magnification with the standard eyepieces.

The resolution power gives the ability to distinguish the main planets details such as the rings of Saturn, the bands and the moons of Jupiter.

Features:

Compact dimensions, ideal for transportation
Practical main mirror focusing mechanism
Universal accessory adaptation
High contrast image without distracting false colour
Quick release system for the tube
Impressive viewing capabilities for its price range
5 years Sky-Watcher limited warranty
