The Skywatchers 120 EDX 0.85x Flattener EvoStar corrects the curvature of the field of view. Your stars stay round and sharp, even at the edges of your image. This is especially noticeable with large camera sensors and short focal ratios.<\/p>\n\n\n\n

The reducer shortens the focal length to 0.85\u00d7. Your image becomes brighter and the required exposure time shorter. Thus, your optics \u201cspeed up\u201d and details become more visible, without having to take long shots.<\/p>\n\n\n\n
The flattener is placed between your telescope and camera. On the camera side, you use an M48 adapter. Within minutes you are ready to start shooting.<\/p>\n\n\n\n
The accessory is lightweight and easy to carry. Your telescope remains stable and vibration-free, keeping every shot sharp.<\/p>\n\n\n\nSpecifications<\/strong><\/h3>\n\n\n\n
