TS-Optics Flattener 1.0x for Full Frame Sensors - M63x1 Connection

The TS-Optics Flattener 1.0x is a field corrector designed for ED and APO refractors with a minimum focal length of approximately 500 mm. Ideal for astrophotography, it corrects the field without altering the focal length, ensuring a fully illuminated and corrected image field for full-frame sensors.

Key Features

• Telescope-side connection: M63x1 thread (male)
• Camera-side connection: M48x0.75 thread (male) and M63x1 thread (female)
• Working distances:
  • 55 mm from the M48x0.75 thread
  • 85 mm from the internal M63x1 thread (without the M63 extension)
  • 73 mm with the included M63 extension tube
• Fully illuminated field: 45 mm, ideal for full-frame sensors
• Correction factor: 1.0 (no change to focal length or focal plane)
• Filter thread: M48x0.75 for 2" nebula filters
• Lenses: 2 elements with multi-coating
• Compatibility: Refractors with a minimum focal length of 500 mm and RC telescopes

Benefits of the TS-Optics Flattener

This corrector offers:

• No changes to the telescope’s focal length, preserving optical quality.
• A fully corrected and illuminated image field for full-frame sensors up to 45 mm.
• Ideal compatibility with ED and APO refractors of at least 4" aperture and a focal length greater than 500 mm.
• Perfect for RC telescopes from TS-Optics and Astro Tech with apertures of 10" or more.

Connecting to the Telescope

The corrector features an M63x1 thread (male) for direct connection to the telescope's focuser. For focusers with different connections, suitable adapters are available.

Recommended assembly order:

1. Corrector (knurled ring facing the telescope).
2. Red spacer ring (included).
3. Transition adapter to M48 thread.

Connecting to the Camera

The TS-Optics Flattener 1.0x offers two options for camera connection:

• M63x1 thread (female):
  • 85 mm working distance, sufficient for accessories such as filter wheels, off-axis guiders, and more.
• M48x0.75 thread (male):
  • Exact working distance of 55 mm, ideal for DSLR cameras (with T-ring) and astro cameras.

Compatibility with Telescopes

The Flattener 1.0x is compatible with:

• ED and APO Refractors:
  • Focal lengths over 700 mm: 55 mm working distance from the M48 thread.
  • Focal lengths between 600 mm and 700 mm: working distance increases by 5 mm.
  • Focal lengths between 480 mm and 600 mm: working distance increases by 10 mm.
  • For shorter focal lengths, a different corrector is recommended.
• RC Telescopes:
  • Apertures of 10" or more.
