  • Adapter M68 Male to M65 Male for SW Esprit Flatteners

    This precision-machined adapter provides a critical M68 male to M65 male connection, featuring a 1.0mm thread pitch on both sides to integrate specific flatteners into modern imaging trains. It is engineered to create a secure, direct-thread attachment between accessories like the Pegasus Astro Falcon v2 Rotator or Prodigy Microfocuser and the stock field flattener of a Sky-Watcher Esprit telescope.

    M68 Male to M65 Male: Connect Your Esprit 100 Flattener

    The primary function of this adapter is to solve a common connection challenge for owners of Sky-Watcher Esprit 100 apochromatic refractors. It allows you to place an M68-threaded device, such as a rotator or electronic focuser, in front of the Esprit's M65-threaded stock field flattener. This creates a rigid, threaded imaging train that eliminates flexure and maintains perfect optical alignment, which is critical for achieving sharp stars edge-to-edge.

    • M68 x 1.0mm Male Thread: Connects to the female M68 threads on devices like the Pegasus Astro Falcon Rotator v2 or the Prodigy Microfocuser (when used with the optional M68F adapter).
    • M65 x 1.0mm Male Thread: Threads directly into the female M65 port on the Sky-Watcher Esprit 100's included field flattener.
    • Solid Mechanical Link: Replaces set-screw or compression ring connections with a direct thread, preventing tilt and ensuring your camera remains perfectly orthogonal to the light path.

  • What is the primary use case for this M68 to M65 adapter?

    This adapter is specifically designed to connect an accessory with a female M68 x 1.0mm thread, like the Pegasus Falcon Rotator v2, to the stock field flattener of a Sky-Watcher Esprit 100 refractor, which has a female M65 x 1.0mm thread.

    Will this M68 to M65 adapter work with my Sky-Watcher Esprit 120 or 150?

    This adapter is specified for the Sky-Watcher Esprit 100. The larger Esprit models use different thread sizes on their flatteners. Always verify the thread specifications of your particular telescope and flattener before purchasing an adapter.

    I want to connect my Pegasus Prodigy Microfocuser to my Esprit 100 flattener. Is this the only part I need?

    No. To connect the Pegasus Prodigy Microfocuser, you will need this M68 Male to M65 Male adapter in addition to the optional PEG-PRDG-M68F adapter, which provides the necessary female M68 port on the Prodigy itself.

    How much back focus does this M68 to M65 adapter consume?

    The adapter itself has a minimal optical path length. However, its exact contribution to your back focus spacing must be measured and factored into your overall imaging train calculation to ensure you meet the flattener's required distance to the camera sensor.

    Are both the M68 and M65 threads on this adapter male?

    Yes, as stated in the title, this is a male-to-male adapter. It features an external M68 x 1.0mm thread on one side and an external M65 x 1.0mm thread on the other.

    Is the thread pitch standard?

    Yes, both threads use a 1.0mm pitch, which is a common standard for M68 and M65 astronomical threads. This ensures compatibility with accessories and focusers designed to this specification.
