- 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 great 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.
- SV503 80mm are suited for those in astrophotography who need something with a wider field of view, wanting to view the sun (be sure to use an approved solar filter) and the moon. Besides, you can also see star clusters, nebula and some larger, brighter galaxies.

Extra-low Dispersion Glass: S-FPL51
ED(Extra-low Dispersion) S-FPL51 is built in SV503 astronomical telescope. ED glass minimizes the effects of the secondary spectrum and reduces chromatic aberration to a remarkable degree. The high-quality 2-Element objective provides sharp and high-contrast images for travel and mobile use.
-
Ultra-wideband Super Multi-coated
Ultra-wideband super multi-coated is claimed as a remarkable seven-layer lens coating process that cuts the reflection ratio down to just 0.2% per lens surface. The result is a dramatic improvement in both color fidelity and brightness and the elimination of flare and ghost images.
-
Dual-speed Rack and Pinion Focuser
The gear ratio of the dual speed 2-inch toothed focuser is 1: 10, which makes it easy to achieve accurate focus. The dual speed focuser can provide two focusing speeds by using a set of co-axial knobs, one for fast focusing and the other for fine focusing.
-
70mm Back Focus
The 70 mm back focus and 360 degree adjustable focuser are sufficient for your astrophotography needs, allowing perfect framing of your astrophotography. And the 2" RAP (rack and pinion) focuser holds more-than-5kg heavy photographic accessories safely.
-
1.5 Arc-second Resolution
The SV503 ED astronomical telescope can reach 1.5 angular seconds to let you see finer details either in astronomy or wildlife viewing.
-
Comes With a 2"-1.25" Adapter
The telescope scope focuser comes with a 2 inch to 1.25 inch adapter. So that you could also use all your 1.25 inch accessories with the SV503 telescope.
