Product Description

Product Info for Sky Watcher Quattro Imaging Newtonian 8in Telescope

The new Sky-Watcher Quattro Imaging Newtonian with dual-speed focuser incorporates a superb mirror-set with two significant advantages over competing products. A 2" dual-speed 10:1 ratio focuser is included for excellent focusing precision. Additionally, the tube length has been slightly shortened to optimize performance for prime-focus photography. Even better performance for astro-photography, and visual use, can be achieved when used in combination with the Sky-Watcher Quattro coma corrector.

Celestron Rowe-Ackermann Schmidt Astrograph Telescopefree Gift Available Save 40% Brand Celestron.

Product Description

Product Info for Celestron Rowe-Ackermann Schmidt Astrograph Telescope

The Celestron Rowe-Ackermann Schmidt Astrograph 91075 has been designed to be perfect for use with top DSLR or astronomical CCD cameras. This Astrograph Telescope from the professional astronomers at Celestron features a 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 Celestron Rowe-Ackerman Schmidt Astrograph Scope offers a full 43.3 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. The Celestron Rowe-Ackermann Schmidt Astrograph is made 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 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 Celestron Rowe-Ackermann Schmidt Astrograph Scope 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.

Features of Celestron Rowe-Ackermann Schmidt Astrograph Telescope:

  • 11-inch f/2.2 optical design with rare-earth glass for images free of false color, coma, and field curvature
  • 52 mm optimized image circle maintains pinpoint stars to the far corners of even the largest astroimaging sensors
  • Custom engineered linear brass focuser bearing reduces image shift, while dual-speed 10:1 FeatherTouch Micro Focus Knob provides the most precise focusing
  • Quiet, high-output 12V MagLev fan reduces cooldown time and blocks dust
  • Common camera adapters (T-thread and M48) included for easy attachment to popular CCD and DSLR cameras

Package Contents:

  • Celestron Rowe-Ackermann Schmidt Astrograph 91075
  • 11-inch optical tube assembly
