Svbony SV503 Telescope ED 102mm F7 Doublet Refractor for Astronomy - F9359D

Highlights

• Rugged housing prevents damage
• Responsive and soft dual-speed focuser
• ED glass (S-FPL51) can produce very beautiful and clear images
• The fully multilayer-coated lens eliminates all reflections on the glass, and has little or no chromatic aberration at high magnification

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

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

The lens adopts optical processing and low polishing technology.

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

Includes metal rings and a 2'' to 1.25'' adapter.
