A 10" F8 carbon fibre truss tube Ritchey Chretien astrograph, with a special chassis manufactured in Europe to Altair Astro's specification.

This "AQ" version of the Altair Deepfield RC Astrograph has been customised with a well-proven, diffraction limited optical system, made by our overseas optical partners. The system features fuzed Quartz primary and secondary mirrors, with modifications to enable a large photographic field. The secondary mirror has a centre-spot for easy collimation.

A significant feature of the mechanical system is the ease with which it can be collimated, as well as very good vibration-resistance. Heavy duty springs and zero backlash locking thumscrews make collimation very easy indeed. Once correctly set up and locked, collimation will not change whilst the scope is on the mount. What's more, this astrograph travels extremely well with little or no adjustment required even after a long road trip. These excellent mechanics, when combined with diffraction-limited optics, give you an astrograph which is reliable, easy to live with, and delivers consistent results time and time again.

A truss-tube design offers better thermal characteristics, afforded by free 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.

The Altair DeepField Ritchey Chretien design is suitable for schools, colleges and universities, or advanced amateur astronomers who want the best quality on the market. The mechanical design has taken over a year to complete and test, having been through three iterations lead managed by Altair Astro. It is available in 10" and 12" versions.
