Product Details

  • The TPO 6-inch f/4 Imaging Newtonian OTA is a portable and affordable, excellent imaging scope. Like all TPO Imaging Newtonian's, the 6-inch model is an ideal scope for anyone looking to transition from visual astronomy into astro-imaging. 

    It’s lightweight enough to be a viable choice with almost any equatorial mount, meaning that you have a wide array of options in terms of mounting and tripod selection.


    Optimum Performance

    The optics on all TPO Imaging Newtonians consist of a parabolic primary mirror and an elliptical secondary, or diagonal. The mirrors are made from B270 white water optical crown glass, which is more thermally stable than glass traditionally used on other reflectors. A 91% aluminum coating is applied, and then over-coated with a layer of quartz for ultimate durability. The primary mirror cell is very sturdy, and has six collimation knobs that can be adjusted by hand. Collimation is made even easier due to the center spot marked on the primary mirror. The diagonal mirror is held in place with a thin four-vane spider.
