新一批振旺光電天文相機HyperStar修正鏡已陸續抵港,組合大大提升了天文攝影的靈活性。只須將Celestron施密特卡式望遠鏡的副鏡更換為HyperStar修正鏡,並裝上ZWO天文相機,便可以f/1.9f/2.0有效焦比拍攝,從而獲得更廣闊的像場及縮短曝光時間達25倍。不少愛好者以單張曝光510秒拍攝,即望遠鏡本身的地平式台架已足應付,不用顧慮場旋問題,亦不用再花錢添置赤道儀,大大減輕出動裝備重量。HyperStar修正鏡及ZWO天文相機絕對是深空天體攝影的好選擇。

A new batch of ZWO astro cameras and Hyperstar correctors are arriving Hong Kong, this combination greatly enhanced the flexibility of astrophotography. By replacing the secondary mirror of Celestron Schmidt Cassegrain telescopes with HyperStar correctors and ZWO cameras, the effective focal ratio of the  system would be shortened to f/1.9 or f/2.0, results in a much wider field of view and 25 times shorter exposure. A lot of enthusiasts take subs of 5 to 10 seconds exposure, that means the telescope Alt-Az mount is able to cater and no need to concern the field rotation, without the extra cost and effort to equip equatorial mounts makes HyperStar correctors and ZWO astro cameras perfect for deep sky imaging with Celestron Schmidt Cassegrain telescopes.
