临交付客人前帮对方拍些照片，也做一下光学检测，刀口仪下的表现十分理想。星河科研社为Sky-Watcher香港独家代理，下一批将会于5月抵港，现接受预订。
Per customer request, took some hardware and Foucault test photos before delivery, the optical figure is very good. Galaxy Scientific Group is Sky-Watcher Hong Kong sole dealer. Next shipment arriving in May, now accepts pre-orders.
