Flattener / Reducer / Correctors
Corrective optics are a very important component, especially in astrophotography. They turn almost every refractor, Newtonian or other telescope into an astrograph. They flatten the image field, shorten the focal length or correct system-related image errors.

Altair GPCAM & Hypercam 0.5x Reducer - Auto Guiding EAA Video Astronomy Solar
Also provides much improved results on refractors with focal lengths narrowly outside this f/range
Increases the field of view and photographic speed, and corrects for field curvature
Images of moon and planets near the horizon become significantly sharper and more detailed
Reduces the focal length of telescopes with the factor 0.67x, thus allowing shorter exposure times.
The 3-element 0.74x reducer and flattener is calculated for apochromatic refracting telescopes.
Full illumination and field correction up to 46 mm diameter (full-frame size)
Optimal for Newtonian telescopes with an f-ratio of f/3 up to f/6
This flattener corrects the field of ED and APO refractors of at least 500 mm focal length for astrophotography without changing the focal length.
Comes with 360° rotation system for optimal camera positioning.
The flattener is also suitable for all refractors up to 350 mm focal length
The kit includes a high-performance reducer, flattener and the "EX TUBE 66" extension rube, which was developed for the FL55SS Fluorite Apo Refractor and improves the photographic performance by flattening the image right up to the edges.
