Product description

For those who want to enjoy outdoor activities in the garden

SV503 80ED telescope’s objective lens features an S FPL-51 extra-low dispersion glass ED element, which virtually eliminates chromatic aberration. This results in the good color correction for an ED doublet lens.

A thoroughly though-out design and high-quality mechanical components. This very special SV503 telescope provides astrophotographers, visual observers or nature watchers with bright, wide field views when observing starry skies or nature watching.

a larger aperture means a larger amount of light will get a brighter picture

The top of the tube rings have 1/4x20 threaded holes to attach a guide scope

The dovetail plate has both 1/4 inch threaded holes to attach to heavy duty tripods

SV503 ED Doublet objective is designed with one S FPL-51 ED Glass and one Lanthanide glass. This extra low-dispersion lens is brighter due to less light absorption, and the multi-layer coating technology minimizes light loss even more.
