Characteristics:
1. The appearance of the telescope is baked with high-end fine-grain paint, with exquisite appearance and delicate feel.
2. The objective lens features S-FPL51 extra-low dispersion glass ED element, which eliminates chromatic aberration. This results in the best color correction for a dual ED lens.
3. The lens adopts optical processing and low polishing technology, which is carefully carved.
4. The deceleration ratio of the two-speed 2'' serrated focusing seat is 1:10, making it easy to achieve precise focusing.
5. If the 70ED is combined with a large chip, a possible way is: The SV193 increases the shooting field of view, which is sufficient for most DSOs. The edges of the stacked image may need to be cropped in post-processing to improve image quality.
