Chinese giant binoculars are more often and widely used due to the ease of use and hand-holdability. But, if an average user can only keep two or three models, is the Chinese binoculars one of the "keepers" for "a life time"? So, it occurred to us that besides Chinese 25/40x100, we should make more "keepers". 

22x100 astronomical is based on such thoughts:

1) Mechanically, it has all-metal body, sturdy enough for life time use.
2) The painted white finish, deep anti-glare shield, a built-in stainless steel mount, and better-looking nylon case.
3) But, the price is just a little bit more than 80mm.

22x100 astronomical is heavier (3.9 kgs for the body), longer (46.5 cm), and so not suitable for handheld use. Optically, it has bak-4 prism, full broadband multi-coating, cnetral focus with right ocular diopter adjustment, long eyes relief, and accessible collimation screws.
