Bague M69 vers M48 - 36.5mm - TSOPTICS

TS-Optics M48x0.75 adapter for the TSFLAT2.5 full size corrector

This adapter allows attaching accessories like camera adapters, off-axis guiders etc. via the 2" filter thread of M48x0.75.

It has been made deliberately with its relatively long optical path of 36.5 mm. As the TSFlat2.5 has a long working distance of 87...106 mm, this adapter allows bridging this distance without unnecessary spacer rings.

Additionally, the adapter provides a 2" filter thread at the inner side. Thus you can attach 2" nebula filters without changing the distance from flattenr to the camera.

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

This focuser is used with the RC telescopes from TS-Optics, Astro Tech, GSO of at least 10" aperture. The adapter fits directly to the female M69x1 thread of these focusers.

Of course, the female M48x0.75 thread of the adapter can be for accepting 2" filters, but also for the adaption of the 2" corrector TSRCFlat2 for RC telescopes.

Then the corrector is sunken into the focuser. The mechanical distance from the male M48x0.75 thread at the camera side to the female thread is 10.5 mm (the male thread is not taken into account). So if you screw the corrector directly into the filter thread, then you have a working distance of 98.5 mm from the M48 thread connector of the adapter.
