Meade - 6" f/5 Newtonian OTA
For replacement item look at celestron 150mm OTA 31057-1
The 6" Newtonian Reflector is like a little brother to the Meade LightBridge Dobsonians. It shares many of the same practical benefits. The scope has enough aperture to offer a serious step up from the average starter scope. But it is still lightweight, portable, and relatively inexpensive.
- Schmidt-Newtonian and Schmidt-Cassegrain optics are mounted in precision-machined aluminum cells and mounted in sturdy steel tubes which are baked with high-grade textured enamel paint. The optical tube assembly is closed, reducing air currents inside the tube. This prevents distortion of an otherwise sharp image. Plus, a closed tube significantly helps keep the optics clean.
- The corrector lens fully corrects for spherical aberration and provides pinpoint star images. Water white glass is used in all Schmidt-Newtonian and Schmidt-Cassegrain corrector lenses to maximize light transmission. The use of water white glass results in an increase of light transmission in excess of 10%, as compared to competing telescopes using soda lime glass.
- Schmidt-Newtonian and Schmidt-Cassegrain corrector lenses and mirrors are individually figured to create a superior optical system which is renowned for its exquisite smoothness and performance.
