TS Optics 3" Field Corrector for RC Astrographs - 68mm Corrected and Illuminated field
TS Optics 3" Field Corrector for RC Astrographs - 68mm corrected & illuminated field
Exceptional results even with full size sensors - the focal lenght is not affected - optimised for f/8 Ritchey-Chretien Astrographs
Direct M48 connection for DSLR cameras
This Corrector for RC - Ritchey Chretien Telescopes is optimized for f8 telescopes.
The RC should be equipped with a 2,5" or 3" focuser. It corrects for the field curvature without changing the focal length. The large free aperture of 68 mm allows illuminiation of full size sensors without vignetting.
The Corrector can be mounted directly to focusers with female M92x1 thread.
Various adapters are also available to connect your RC telescope.
Scope of delivery:
The corrector comes with a M48 adapter. Using a M48 bajonet ring, you can attach your DSLR camera directly and achieve good results. If using full size sensors, it might be necessary to fine tune the distance with spacer rings between corrector and camera.
Recommended working distances for individual adaptations: The camera side thread is M80x1 - the distance from the M80x1 thread to the camera sensor should be 103mm.
