  • Adapter M74 Female to M68 Male (For SW Esprit 100)

    This Pegasus Astro Adapter M74 Female to M68 Male provides a secure, direct-thread connection for the Falcon Rotator v2 to the stock focuser of a Sky-Watcher Esprit 100 telescope. The adapter consumes exactly 8.5 mm of back focus, featuring a 6 mm long female M74x1 thread on the telescope side and a 6 mm long male M68x1 thread on the rotator side.

    Esprit 100 to Falcon Rotator v2 Connection: An 8.5mm Back Focus Solution

    Achieving a rigid, perfectly aligned imaging train is critical, and this adapter is engineered specifically for that purpose. It bridges the M74 female thread on the Esprit 100's focuser drawtube to the M68 female thread of the Pegasus Falcon Rotator v2. Its 8.5 mm thickness is a key dimension for calculating the final back focus of your imaging train, ensuring sensors land at the optimal focal plane.

    • Telescope Side Thread: Female M74 with a 1.0mm pitch and 6 mm of thread length provides a secure fit onto the Esprit focuser.
    • Rotator Side Thread: Male M68 with a 1.0mm pitch and 6 mm of thread length ensures a solid connection to the Falcon Rotator v2.
    • Minimal Optical Path: At only 8.5 mm thick, the adapter preserves precious back focus for use with filter wheels, off-axis guiders, and cameras.

  • What is the primary function of this M74 to M68 adapter?

    This adapter is designed to connect the Pegasus Astro Falcon Rotator v2 directly to the stock focuser of a Sky-Watcher Esprit 100 telescope. It converts the M74 female thread of the telescope's focuser to the M68 male thread required by the rotator.

    How much back focus does the M74 to M68 adapter consume?

    The adapter has a precise thickness of 8.5 mm. You must include this value in your total back focus calculation when setting up your imaging train with the Esprit 100 and Falcon Rotator.

    Will this adapter work with other telescopes besides the SW Esprit 100?

    While designed for the Sky-Watcher Esprit series, it may be compatible with any focuser that presents a female M74x1 thread and requires a male M68x1 connection. However, its primary tested and intended use is with the Esprit 100.

    How do I install this adapter on my Sky-Watcher Esprit 100 focuser?

    Installation is straightforward. First, unthread the stock visual back or camera adapter from your Esprit 100 focuser drawtube. Then, carefully thread the M74 female side of this adapter onto the exposed male threads of the focuser until it is snug. Finally, thread your Falcon Rotator v2 onto the M68 male threads of the adapter.

    Are the M74 and M68 threads on this adapter a standard pitch?

    Yes, both threads use a standard 1.0mm pitch. The M74 female thread has a length of 6 mm, and the M68 male thread also has a length of 6 mm, ensuring a secure grip on both sides.

    Does this adapter cause any vignetting with the Falcon Rotator v2 and an Esprit 100?

    This adapter is designed to provide a clear light path between the Esprit 100 focuser and the Falcon Rotator v2. The M68 connection is large enough to prevent vignetting with most common full-frame and smaller astronomy camera sensors.
