Antares M44.5 Maksutov Visual Back with 1.25" Twist Lock Holder

The new Antares M44.5 Maksutov Visual Back is designed to provide a secure and versatile connection for your Maksutov telescope accessories. Featuring an innovative twist-lock mechanism and additional functionality, this adapter is perfect for astronomers seeking a reliable and adaptable solution.

Key Features:

• M44.5x1 Female Thread Compatibility:
  Designed to attach to many Maksutov telescopes with a female M44.5x1 thread, commonly found on models by Orion, Sky-Watcher, and other manufacturers.

• Twist-Lock Mechanism:
  Equipped with a knurled ring and a compression band, the twist-lock holder ensures a firm grip on your 1.25" diagonals, eyepieces, and accessories, providing stability and ease of use.

• Dual Functionality:
  Unscrew the silver lock ring to reveal a male T-thread on the lower black barrel. This clever design allows the adapter to double as a Maksutov-to-T Thread adapter, effectively giving you two adapters in one.

• Included Accessories:
  Comes with a 1.25" dust plug to protect your equipment when not in use and a rubber O-ring to ensure compatibility with male SCT threads that may be longer than the adapter’s female thread. This O-ring should not be needed for most applications but is included for added flexibility.

Important Notes on Maksutov Telescope Threads:
Many Maksutov and Maksutov-Cassegrain telescopes feature a rear male thread with an M44.5x1 specification (44.5mm diameter, 1mm thread pitch). While this is common, it is not a universal standard.

• Some Mak telescopes use a smaller T/T2 thread (M42x0.75).
• Larger Maks may use a standard SCT thread (2"-24TPI).

If you are unsure whether this adapter is compatible with your telescope, it is recommended to consult your telescope manufacturer or measure your thread diameter before purchasing.
