Description
Description
Dedicated 2" flattener by William Optics optimized for use with their Z73 full-frame Apo telescope.
- Features an M63 male thread for a direct threaded connection to the Z73 on the telescope side.
- On the camera side, the flattener has a male M48x0.75 thread. You can use your Canon or Nikon DSLR directly with the use of an optional M48 camera-specific T-ring (sold separately).
- With this, your camera chip will be placed at the correct 55mm working distance.
- Note that you cannot use this with the smaller T rings that have a 42mm T thread.
- For other cameras with shorter back-focus, you will need to add additional spacers/adapters to acheive the required working distance.
- True 1:1 flattener with no reduction.
- The WO Flat73A also has a female M48x0.75 (2" filter thread) on the inside to which you can attach standard 2" filters. Since the male thread of your filter will face the telescope within this item, you can only use bidirectional filters with this item in which the orientation of the filter does not matter.
- A very neat fature of this item is that a rotator/camera angle adjuster is built into the mechanism of this item, making a separate rotator unnecessary.
Compatibility:
- Zenithstar 73
- Back Focus: 66.2mm
- Adjust Distance: 11.4mm
- Image Circle: ∅43mm
Specifications:
- Lens Type: 2 Groups 2 Elements
