Reducer/Corrector 3" 0.7x

The flattener is a lens that evens out the field, as this is slightly curved by the primary optics. This curvature causes stars that are imaged at the edge of the field of view to be less sharp. The flattener, also called a field flattener, corrects this effect. Astrophotographers can then enjoy images where the stars remain sharp right out to the edge of the exposure. The flattener is installed between the telescope and the camera.

Reduces focal length by a factor of 0.7x (at f/8) and 0.8x (at f/10).

The reducer/corrector not only reduces focal lengths, but also levels the field. Although originally calculated for the 127mm and 152mm Explore Scientific ED-APOs, the reducer can be used on many systems.

The flattener/reducer comes with:

• 3” container for the telescopic side
• Adapter for M54x0.75 focuser
• M42x0.75mm T2 camera adapter
• Dust cap

The telescopic side of the flattener has an internal M76x0.75 thread and an external M72x0.75 thread for attaching accessories.
