TS-Optics adapter from M69x1 to M48x0.75 for TS 2.5" flattener and TSLPR3 Monorail focuser

TS-Optics M48x0.75 Connection Adapter for the TSFLAT2.5 full-frame corrector

The adapter allows the connection of accessories such as camera adapters, off-axis guiders ... via the 2" filter thread M48x0.75. The relatively long design of the adapter of 36.5 mm is intentional. The TSFLAT2.5 has a relatively long working distance of between 87 mm and 106 mm. The transition adapter allows space-saving adaptation of accessories without unnecessary extension rings.

The adapter also has a 2" filter thread on the inside. This allows you to connect 2" nebula filters without changing the distance between the flattener and the camera. The adapter can also be unscrewed. This makes it easy to insert 2" filters. The intermediate thread is the common M68x1 thread.

TS-Optics M48x0.75 connection adapter for the M69x1 female thread of the TSLPR3 3" Monorail focuser

This focuser is used on the RC telescopes from TS-Optics, Astro Tech, GSO from 10" aperture. The adapter fits directly to the female M69x1 thread of these focusers. The female M48x0.75 thread of the adapter can of course be used for 2" filters, but also for adapting the 2" corrector for RC telescopes, TSRCFlat2. The corrector is then sunk into the focuser. The mechanical distance from the M48x0.75 external thread on the camera side to the internal thread is 10.5 mm (not counting the external thread). So if you screw the corrector directly into the filter thread, you have a working distance of 98.5 mm from the M48 threaded connection of the adapter.
