William Optics New Adjustable Flat73A for Z73

This dedicated 2" field flattener by William Optics is precisely engineered for full-frame imaging with their ZenithStar 73 Apo telescope.

Key Features:

Direct M63 male thread ensures a secure, threaded connection to the Z73 telescope.

• Camera-side connection: Male M48x0.75 thread allows attachment of Canon or Nikon DSLRs using a camera-specific M48 T-ring (sold separately).
• Provides the correct 55mm working distance when paired with a compatible T-ring.
• Not compatible with smaller M42 T-thread rings.
• For cameras with shorter back-focus, additional spacers/adapters will be required.
• True 1:1 flattener – no focal length reduction.
• Built-in female M48x0.75 filter thread supports standard 2" filters (must be bidirectional since filter orientation faces the telescope).
• Integrated rotator mechanism eliminates the need for a separate camera rotator

Compatibility:

•  Specifically designed for William Optics ZenithStar 73
