Features
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 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. 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;
5. If the 70ED is matched with a large chip, A possible way is to: The SV193 increases the field of view of the shot, which is sufficient for most DSOs. The stacked image edges may need to be cropped in the post-process to improve image quality.
