TS Optics PHOTOLINE 1.0x APO Full Frame Size Flattener with M68 connector
This corrector is suitable for refractors starting from 700 mm focal length. It works, among others, very well with the PHOTOLINE apochromats and with the TS-Optics ED refractors from 4" aperture upwards. The corrector offers 100% illumination and correction up to 45 mm (image circle), so it can very well used for cameras with full-frame sized sensors.
Connection to the focuser
The corrector has an M68x1 ZEISS style thread (male) at the telescope side. Many focusers already have the matching female thread. For other focusers, for example with M63x1 thread connection, there are matching conversion adapters.
Connecting the camera
The corrector offers two possibilities for the connection of the camera:
The flattener is suitable for the following telescopes and for telescopes with similar focal length and focal ratio:
Directly to the corrector, there is a male M63x1 thread. The generous working distance from this thread is 103 mm. Thus you have enough space for accessories like filter wheels, off-axis guider and much more.
There is also a conversion adapter to M48x0.75 included in the scope of delivery. The working distance from this thread is exactly 55 mm. This is perfect for attaching DSLR cameras (just T-ring + camera) or astro cameras. The adapter makes sense if the camera should be directly connected to the corrector.
