    This adapter allows to install the M63 APM-Riccardi Apo reducer inside the focuser barrel of different 3" focuser with M68x1 thread:
    • APM 3" ZTA Focuser
    • Baader 3" Steeltrack
    • TS 3" Crayford Focuser
    • TS 3" Linear Power Focuser
    • 3" Focuser at new Esprit Skywatcher Apo
    With this adapter, the correct screw connection of correctors for astrophotography is easy. In addition, it enables stable, short construction adaptation to M48 . Its overall length is only 6.3 mm .


    The installation is very easy. The reducer will be screwed onto the adapter with its M63 female thread. The whole system will than be screwed into the M68 thread of the focuser. This way the reducer totally disappears in the focuser. This allows the use of the reducer, which needs a backfocus of 170 mm, with refractors, which do not have such a large backfocus. The only prerequisite is that the reducer fits into the focuser barrel.

    Assembly at camera side

    On the M48 thread at the camera side you can now mount the required accessories like:
    • Off Axis Guider
    • Filters Drawer for 2" Filter
    • Filterwheel
    • Extension Tubes for maching exact backfocus
    • Adapter to T2

    Adapter length

    The length of the adapter is only 6.3 mm. Both threads will not be included because these threads will completely disappear in any further adaption or accessory.

    Classic adapter

    In addition, it represents a classic adapter from M63 and M68 to M48 for all focusers with these female threads, for example:
    • APM ED Refraktoren
    • APM 107-mm-Apo
    • Alle Skywatcher ESPRIT Apos
    • Alle LZOS Apos mit Okularauszügen ab 2,5"
    • Alle TS PHOTOLINE APOs mit Okularauszügen ab 2,5"
    At the telescope side the adapter also features a M48 female thread for the adaption of 2" filters or other 2" accessories.
