All in all, I had a fun time testing this OTA. If you have a smaller sensor camera and want the convenience of a small OTA that an SCT offers and do not want to mess around with focal reducers the Meade F/6.3 OTA’s are a very nice option for deep sky EAA. I still do think that an F/10 OTA with f/6.3 reducer is a better way to go as you also have a better planetary scope if you want to observe or image those.
F6.3. Wide field version版本對於APS-C相機有很好的成像品質. 如圖。但不適和行星放大成像。要行星放大比較合適用F10的版品。
