The Teleskop Service 1.0x Flattener for RC Telescopes - Full-sized M68 Connection is for all RC telescopes at f/8 which have a 2.5-inch or larger focuser attached. This flattener corrects the field without altering the focal length. It has a clear aperture of 60 mm allowing full illumination of full-frame sensors when properly installed.
This corrector provides a generous working distance of 89.5 mm from the female M69x1 thread on the camera side. TS-Optics offers all necessary adapters for attaching your camera with the optimal distance. See below for connection examples.
Connecting DSLR Cameras - In order to connect a DSLR and astro camera with an M48x0.75 thread, you can use the adapter M69A-M48A. You will have exactly 55 mm from the M48 thread to the sensor position. This equates to a T-ring and DSLR camera.
Connecting Zeiss Style M68x1 Adapters System - The adapter M69a-M68a provides an M68x1 connection to the TSRCFLAT3. The working distance from the M68 thread to the sensor is 84.2 mm, so you have enough space for your adaption.
Connecting the M48x0.75 Adapter System - Almost any OAG and many filter wheels have the M48 connection at the telescope side, or can at least be adapted to this thread. With the adapter M69-M48, you will get a very short transition to M48 with only 1 mm length.
Extension Tubes for Female M69x1 Thread - In order to maintain the optimal illumination, one should adapt to smaller threads as late as possible. For this application, TS-Optics also offers a 30 mm and 10 mm extensions. They are screwed directly into the camera side thread and will reduce the remaining working distance correspondingly.
The TSRCFLAT3 has a male M68x1 thread on the telescope side, and TS-Optics offers adaptions for all established focusers. Particularly important is the adaption to the female M69x1 thread of the MONORAIL focusers of TS-Optics, AstroTec, GSO, and RC telescopes. In order to adapt the TSRCFLAT3 to the focusers, you need:
