M57 Version of Feather Touch Focuser

For Borg and many other Japanese-made telescopes, a version of the Feather Touch Focuser with a metric M57 interface is available. Use of this coupling allows for the direct attachment of many available Borg accessories and has the additional benefits of providing a larger opening with a very rigid connection, compared to coupling with the alternative 2" nose-piece coupling.

Above, the M57 Feather Touch Focuser is shown in a photographic configuration with Borg camera rotator ring 7352, 0.85x focal reducer 7887, and the available motorized focuser option. For visual use, Borg M57 extension/2" accessory holders such as part #7504 may be substituted for the rotator ring and focal reducer.
3.5" Focuser Adapter
This accessory interfaces to the Feather Touch 3.5" focuser on large scopes (such as those produced by TEC) and allows the use of Borg M57 accessories.
