A 12" F8 carbon fibre truss tube Ritchey Chretien astrograph, 100% jointly designed and manufactured in UK and Europe, to the highest specification.

This is the all-Quartz version which has both primary and secondary mirrors made from fused Quartz. 

The Altair DeepField Ritchey Chretien design is a professional observatory grade imaging instrument, suitable for schools, colleges and universities, or advanced amateur astronomers who want the best quality on the market. 

We have chosen a truss-tube design because of the better thermal characteristics afforded by air circulation around the optics, almost eliminating the contrast-robbing effects of boundary air current layer formation, as well as allowing the optics to come to thermal equilibrium faster. This is also an extremely rigid design, which ensures optimum performance for the most demanding imaging requirements.
