The Baader M68-Tilter
(#2458170 , € 255)
The M68 system allows for a sturdy and rigid connection of heavy accessories. The Baader M68-Tilter
(#2458170 , € 255)
is a relatively recent addition to this family of adaptors and was developed to easily compensate for image tilt in an optical train through simple adjustments of three pairs of easily-accessible (even when a camera for example is attached) hex-screws located around the edge of the adaptor. Although the M68 tilter itself is small occupying just 9.50-10.25mm of optical path length, and relatively light weighing in at just under 100g, it can accommodate a heavy accessory payload of up to 5kg. The tilter allows a tilt shift of up to 1° to compensate for misalignments in the image field.
