◆ Mewlon Flattener/Reducer
Due to relatively large coma, the Mewlon-180C is not suited for deep sky imaging at prime
focus. However, you can enjoy deep sky imaging using the Mewlon f/9.8 Flattener/Reducer,
which decreases the focal ratio to f/9.8 and reduces coma.
Focal Length : 1760mm
Focal Ratio : f/9.8
