Explore Scientific 80mm f/6 Essential Apochromatic ED Triplet Refractor Telescope
*Includes 2” Dielectric quality Diagonal with 1.25” Adaptor.
The ED80 80mm f/6 Essential Apochromatic ED Triplet Refractor Telescope from Explore Scientific features a triplet apochromatic lens system with Extra-low Dispersion (ED) glass and Explore Scientific's own proprietary anti-reflection EMD fully multicoated optics.
This combination of glass, lenses, and coatings virtually eliminates chromatic and spherical aberrations for clear and bright images without distortion across the entire field of view, with true color rendition.
This is a delightful and versatile optical tube assembly that can be employed as a simple grab-and-go primary telescope. You can also use it as as a large finderscope mounted to a larger scope such as a Dobsonian, or set up on a dual-mount rig for astrophotography/astroimaging.
A mounting cradle-ring clamps over optical tube assembly (OTA).
The cradle-ring assembly allows the user to adjust the orientation and position of the scope relative to the mount to optimize viewing comfort and balance, while avoiding interference with other equipment. Sports an industry standard Vixen-style dovetail plate makes it compatible with any alt-az or equatorial mount with a Vixen-style saddle. Its two-speed rack-and-pinion focuser helps make fine-focusing fast and precise.
A 90° star diagonal is also included for more comfortable viewing.
The mirror has dielectric coatings for a 99% light transmission for minimal light loss when using it.
Includes a mounting bracket for a finderscope built-in.
Beautiful sliding Dewshield makes this telescope as compact as they come .
You would be hard pressed to find a better deal in a compact 3-element Apo. Optical tube assembly.
