Extra-low dispersion glass; SV503 Telescope OTA is designed with ED glass; will give you the crystal clear image; SV503 80ED telescope produces an especially colour true and high contrast image; just right for more discerning observers
SV135 7 mm to 21mm adjustable focal length;SV135 7-21mm zoom eyepiece equivalent to multiple eyepieces ;obtain higher magnification with short focal length;It could bring you a better observation experience in a comfortable situation with high-contrast imaging
The value must have 2x barlow lens doubles the magnification of any 1.25 inch eyepiece;double the capacity of an existing set eyepieces at the cost of a single eyepiece
UHC filters or light pollution reduction filters are designed to selectively reduce the transmission of certain wavelengths of light;especially those produced by artificial light
Dielectric coatings; super flat mirror with dielectric coatings to reduce reflected light loss; provide an over 99% reflective surface; good for astronomical viewing
Description
SV503 80ED telescope's objective lens features an S FPL-51 extra-low dispersion glass ED element and FMC coating, which effectively eliminates chromatic aberration. This results brings you images with true colors and high contrast.1.25in nosepiece fits telescopes with 1.25in focusers.
