The 10" f/4 Newtonian Reflector Astrograph's 250mm (9.8") parabolic primary mirror is made of low-thermal-expansion BK7 glass, which is superior to standard soda-lime glass. The 1000mm focal length is ideal for framing a wide variety of celestial targets! The enhanced aluminum mirror finish has 92% to 95% reflectivity and is coated with a protective layer of SiO2 (quartz). The 88mm minor axis secondary mirror provides excellent full-field illumination with modern cameras, with minimal light drop-off at the edge of APS-C sized sensors. The rear cell features large collimation knobs and a built-in fan to speed cooling of the mirror (requires 8 AA batteries, not included). The mirror is center marked to aid in precise aligning. Great value!
The machined 3" dual-speed (10:1) Crayford focuser boasts a linear bearing design, which adds rigidity to the drawtube to support heavier imaging loads. A steel reinforcing plate directly under the focuser eliminates flexure between it and the tube.
