1. The appearance of the telescope is baked with high-end fine-grained paint, with exquisite appearance and delicate feel2. The objective lens features a S-FPL51 extra-low dispersion glass ED element, which eliminates chromatic aberration. This results in the best color correction for an ED doublet lens3. The lens adopts optical processing and low polishing technology, which is carefully carved4. The deceleration ratio of the two-speed 2'' toothed focusing seat is 1:10, which makes it easy to achieve accurate focus sv503 collocation recommended
ED(Extra-low Dispersion) S-FPL51 is built in SV503 astronomical telescope. ED glass minimizes the effects of the secondary spectrum and reduces chromatic aberrationto a remarkable degree. The high-quality 2-Element objective provides sharp and high-contrast images for travel and mobile use.
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.
