昨晚測試新到的Sharpstar 50EDPH，接上ZWO 2600MC Duo拍攝，APS像場下修正度不俗，以3000多元連平場減焦鏡計，性價比十分高，而且也十分輕巧。

The newly arrived Sharpstar 50EDPH was test with ZWO 2600MC Duo last night. The correction over APS format was very good. Considering the price of just over HK$3000 with reducer include, it offers excellent cost performance, and light weight. 

以下為照片全圖及4角截切，無平場。同樣，為減輕裝備總重量，赤道儀沒有用平衡錘，只接了一條彈簧便可以。
