This 70mm SV503 multi-function OTA is suitable for shooting sun and moon, landscape scenery and deep space photography.
It works better with 1/2 or 1/3 inch sensors and 3μm-5μm pixel size cameras.
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 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.
If the 70ED is matched with a larger camera chip, it's best to crop images for the best effect
