星河科研社为锐星光学Sharpstar / Askar的香港独家总代理，3款望远镜及其配件现已接受预定。50EDPH 预计12月上旬到货；140APO 预订后大概12月初后有货，185APO 预订大概2024年1月后有货，但一切以厂方消息为准。

Galaxy Scientific Group, the exclusive distributor of Sharpstar and Askar in Hong Kong, is now accepting pre-orders for three telescopes and their accessories. The expected arrival time for the 50EDPH is early December, while the 140APO is expected to be available in early December after ordering, and the 185APO is expected to be available after January 2024, but subject to confirmation by the manufacturer.

Sharpstar EDPH系列新推出的50EDPH，口径50mm，焦距275mm，原生焦比F5.5，包含燕尾板整体重量约1.07kg，总长度196mm。三片式全分离的APO设计，包含两片ED玻璃，不但可以目视，亦可连接行星相机拍摄，配合专用减焦镜整体焦比可降至F4.6，小巧轻便但功能齐全。

Sharpstar 50EDPH is a newly introduced telescope with a 50mm aperture, 275mm focal length, and a native focal ratio of F5.5. It weighs approximately 1.07kg and has a total length of 196mm, including the dovetail plate. The telescope features a triplet air-spaced APO design, including two ED glasses. It is suitable for visual observation and can also be used for planetary imaging with a dedicated focal reducer, which reduces the focal ratio to F4.6. Despite its compact and lightweight design, the Sharpstar 50EDPH offers full functionality.

Askar 继120APO后，新推出两款大口径折射镜140APO & 185APO，为天文爱好者提供新的选择：

Askar has introduced two new refractor telescopes, the 140APO and 185APO, following the 120APO, providing new options for astronomy enthusiasts.

Askar 140APO 口径140mm，焦距980mm，原生焦比F7，极限星等可达12.5；而Askar185APO 口径185mm，焦距1295mm，原生焦比F7，极限星等可达13.1。

Askar 140APO has a 140mm aperture, 980mm focal length, and a native focal ratio of F7, with a maximum limiting magnitude of 12.5. While Askar 185APO has a 185mm aperture, 1295mm focal length, and a native focal ratio of F7, with a maximum limiting magnitude of 13.1.

两款光学镜筒均采用三片式APO全分离镜片设计，其中含有一片ED玻璃。考虑了镜筒便携性，后段亦有可伸缩镜筒设计，镜筒缩排状态下，可搭配双目观测器使用；镜筒伸长状态下，则可搭载专用0.8x减焦镜或1x专用平场镜进行拍摄或使用天顶镜及目镜进行目视观测。

Both telescopes feature a triplet air-spaced APO design, including one ED glass element. The telescopes have an integrated retractable design. When the lens tube is contracted, they can be used with a binoviewer for visual observation. When the lens tube is stretched, they can be connected with a specific 0.8x reducer or 1.0x flattener for imaging or a diagonal and eyepiece for observing.
