TS-Optics adapter to M48x0.75 internal thread for UNC and TeleVue focusers

TS-Optics connection adapter for correctors on TS-Optics UNC focusers and on M65x1 thread

Many astrophotographers prefer a bolt-on adaptation because the coma corrector or flattener can tilt due to lateral clamping. The result is distorted stars at the corners and unsightly astrophotos.

For this reason, TS-Optics 2" UNC focusers have the M65x1 thread at the end of the 2" barrel. With this adapter, offsets can be connected without clamping and thus without loss of the required accuracy. The clamping screws on the focuser are therefore superfluous.

Correctors with threaded connection M48x0.75

The adapter is screwed into the M48 thread of the corrector. The internal thread of the adapter is only 2mm long. Therefore, there is still enough room for adaptation, since the connection thread of the correctors is usually 4-5 mm long. The corrector with adapter is then simply screwed onto the focuser.

Baader MPCC Coma Corrector

The adapter is perfect for this. Remove the protective ring from the external thread M48x0.75 of the corrector. Then screw the comma corrector into the adapter. You can then screw both together with the UNC excerpt. You can then use the MPCC's T2 thread for all other adaptations.

Correctors and flatteners with T2 connection

The correctors with the smaller connection thread M42x0.75 can also be used in the future on UNC focusers without clamping. Insert the corrector in the extract. Then simply twist the TS65-M48i adapter over it and lock the bracket in place. The adapter now fulfills the function of a union ring.
