SV503 102F7 ED Astronomical Telescopes OTA

IMPORTANT: Filter Compatibility

The SV503 102ED only supports the use of 1.25" filters. Please note that it will not work with 2" filters or other filter sizes. Please be sure to confirm the size when purchasing filters.

Features

1. 1. The appearance of the telescope is baked with high-end fine-grained paint, with exquisite appearance and delicate feel

2. 2. The objective lens features an S-FPL51 extra-low dispersion glass ED element, which eliminates chromatic aberration. This results in the best color correction for an ED doublet lens

3. 3. The lens adopts optical processing and low polishing technology, which is carefully carved

4. 4. The deceleration ratio of the two-speed 2'' toothed focusing seat is 1:10, which makes it easy to achieve accurate focus

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 SMC

SMC 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.

90mm Back Focus

The 90 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.

1.17 Arc-second Resolution

The SV503 ED astronomical telescope can reach 1.17 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.

CNC Machined Technology

Metal Hoop with Dovetail

The SV503 comes standard with adjustable tube rings and dovetail which allows it to attach to most telescope mounts. In addition, there are 1/4 inch threaded holes on the dovetail plate to attach to tripods and M6 holes on top of the tube rings to attach a guide scope.
