Product description

Stunning astrophotos and extreme depth at a moderate time effort - this is what the powernewtonians stand for. Thanks to the fast system. You can gather enough raw material for an entire object in one night.

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.

Orion UK Secondary Mirror 88mm: Instead of the standard a 88mm 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 25mm. 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.
