昨晚测试新到的Sharpstar 50EDPH，接上ZWO 2600MC Duo拍摄，APS像场下修正度不俗，以3000多元连平场减焦镜计，性价比十分高，而且也十分轻巧。

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. 

以下为照片全图及4角截切，无平场。同样，为减轻装备总重量，赤道仪没有用平衡锤，只接了一条弹簧便可以。

Photos below are full image and crop from 4 corners, no flat field. Again, to reduce the overall weight of the equipment, the equatorial mount does not use a counterweight and only relies on a single spring.
