Product Details

  • The EFW3 holds up to seven 50.8 mm unmounted filters making it ideal for large sensor cameras. With seven positions you will be able to house LRGB, H-alpha, Sii, and Oiii filters in the same carousel.

    For a large filter wheel, the EFW3 has a slim lightweight design, weighing 1.87-pounds (850 g) with dimensions of 9.37" x 8.39" (238 mm x 213 mm). It is fully compatible with any Atik camera when using the supplied M54 or M42 adapters. The backfocus is 21.8 mm, minimizing backfocus requirements. It is machined from solid aluminum to produce a durable and quality wheel that will keep turning, night after night.

    Atik 16200 users can attach the EFW3 directly to the camera to minimize back focus. With the front plate attached, the backfocus of the 16200 and EFW3 is 41.5 mm, while the backfocus with the front plate removed is just 34.5 mm

    The EFW3 Has a full ASCOM driver allowing users to use with almost any PC software and can also be controlled using Atik's Artemis Capture software.
