Celestron Rowe-Ackerman Schmidt Astrograph

NEW Celestron astrograph telescope featuring 11" f/2.2 Rowe-Ackermann Schmidt optics and rare-earth glass for images free from false colour, coma and field curvature.

70mm imaging circle ensures pinpoint stars to the edges of the largest imaging sensors.

Custom engineered linear brass focuser bearing reduces image shift and a dual-speed 10:1 FeatherTouch micro focuser ensures precise, smooth focussing.

Built in, quiet, high-output 12v MagLev fan to reduce cooldown time and block dust.

Capturing impressive deep-sky astroimages is easier than ever with Celestron’s new Rowe-Ackermann Schmidt Astrograph, the perfect companion to today’s top DSLR or astronomical CCD cameras. This fast, wide-field f/2.2 system offers two huge advantages over traditional f/10 astroimaging: better apparent tracking and shorter exposures. That means you’ll create better-looking astroimages in a fraction of the time, even without the use of an autoguider.

The Rowe-Ackermann Schmidt Astrograph builds on the legacy of Celestron’s Schmidt Camera, which allowed astrophotographers to produce images on film in the 1970s.

Today, with CCD sensor sizes as large as film—or larger—the Schmidt Astrograph offers a full 70 mm optimized image circle to capture pinpoint stars on the largest imaging chips. Combine this large image circle with a focal length of just 620 mm and you have an instrument suitable for wide-field imaging, creating huge mosaics of the night sky, surveying, and even comet hunting.

Optical Performance

The Rowe-Ackermann Schmidt Astrograph features newly designed optics with 4-element rare-earth glass for images free of false color and aberrations like coma and field curvature. The optical quality and spot size across the entire image circle is unprecedented for an astrograph in this price range—or even that of a much more expensive instrument. The design also provides minimal vignetting.

Advanced Features

Advanced features like a custom engineered linear brass focuser bearing and FeatherTouch Micro Focus Knob allow you to make the fine adjustments you need to capture the perfect shot. Meanwhile, a12V MagLev fan reduces cooldown time and provides optimal airflow through the dust filtered optical tube.

Engineered as a complete astroimaging system, every component of the Rowe-Ackermann Schmidt Astrograph is optimized for peak performance with DSLR and astronomical CCD cameras. Down to the thickness of the glass used in the included fully-multicoated optical window or an optional imaging filter, every component of the system has been taken into careful consideration to work together seamlessly.

Skywatcher Skymax 180 Black Diamond Maksutov

The SKymax 180 Maksutov is now avaialble in Skywatchers Black Diamond finish.

This scope features razor sharp optics and a comparitively small central obstruction.

The result is a scope that provides excellent high power views with very good contrast. this is an ideal instrument for lunar and planetary use and also provides very good performance fopr deep sky work when sued with an appropriate long focal length eyepiece.

Skywatcher Explorer 190 MN Pro

AN ASTROPHOTOGRAPHERS DREAM TELESCOPE!!

The exciting new Maksutov-Newtonian from Sky-Watcher is just what astrophotographers and serious visual observers have been looking for.

The Maksutov-Newtonian design combines the best features from the Newtonian Reflector and the Maksutov-Cassegrain to create a telescope design that provides truly stunning image quality, providing high-contrast, perfectly flat images, free from false colour. The Maksutov-Newtonian design provides large aperture Apochromatic performance, with exceptional field correction, in a compact, amazingly affordable package. Stars appear as classic pinpoints across the entire field. Perfectly optimised for modern DSLR cameras as well as Cooled CCD Camera's

The premium optics are housed in a robust rolled-steel tube for excellent mechanical integrity. Five internal knife-edge baffles are included to eliminate internal reflections and further enhance contrast. The Primary Mirror is made of low thermal expansion Pyrex® glass for a significantly reduced cool-down time.

Compared to a similarly sized Schmidt-Newtonian, the Maksutov-Newtonian yields a sharper and more contrasty image. Naturally, the Maksutov-Newtonian is an excellent visual performer too!!
