Product description

Extreme longtime exposures for deepest images and faintest details are a thing of the past! With the 8" f/2.8 astrograph you are able to produce sharper and more detailed images of deepsky objects in a comparable short time. Clear nights are more than rare so start collecting as much data as you can - in all channels.

Carbonfibre Tube: We replace the standard metal tube by an optimized carbonfibre tube. By reducing the telescopes weight, it´s rigidity increases clearly. That is essential for an f/2.8 system.

Better Focuser: The very basic Boren Simon focuser is being replaced by a much more rigid and low profile UNCN2-G2 focuser that carries even higher loads and heavy cameras without flexing problems.

Optimized Focus: Using the low-profile Steeltrack offers the advantage to reduce the focal area down from 165 mm to 131 mm above tube. You`ll receive a much better illumination without focussing problems.

Orion UK Secondary Mirror 75 mm: Instead of the 70 mm standard a 75 mm secondary with Orion 97 % HILUX coating is used. Besides the instrument is optimized with the correct offset.

The Astrograph is an optimized system for being used in combination with DSLR cameras, it fully illuminated a diameter of 25 mm. That is more than most f/4 or f/5 Newtonians and the secondary mirror guarantees a fully illumination of the correctors field lens. The astrographs compressor can easily be replaced by a coma corrector. There won´t occur any problems to reach focus.
