SV503 Telescope ED 80mm F7 Doublet Refractor OTA for Exceptional Viewing and Astrophotography

SV503 80mm F7 astronomy telescope SV503 would be better begin for astronomy amateurs to do astrophotography. For those who want to enjoy outdoor activities in the garden.

1. 80mm Ultra-clear Refractor Telescope
A larger aperture means a larger amount of light will get a brighter picture.

2. ED Lens - Effectively Eliminate Chromatic Aberration
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.

3. Dual Speed Focuser
The gear ratio of the dual speed 2-inch toothed focuser is 1: 10; which makes it easy to achieve accurate focus.

4. 360 Degree Rotating

5. Deep Space Astrophotography
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.
