Missing Lens Cap
This 70mm SV503 multi-function OTA is suitable for shooting sun and moon, landscape scenery and deep space photography.
The finish of the telescope is baked with high-end fine-grained paint, with exquisite appearance and delicate feel.
The objective lens features an 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 ratio of the two-speed 2'' toothed focusing seat is 1:10, which makes it easy to achieve accurate focus.
