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

2. 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 lens

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

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