  • Lhires III adapter set (23 mm camera)

    The Shelyak Lhires III adapter set for 23 mm cameras enables you to mount a camera with a native backfocus between 21.35 mm and 25.35 mm to your Lhires III spectroscope, ensuring the sensor is positioned at the precise focal plane required for high-resolution spectroscopy.

    Precision Mounting for Cameras with 21.35mm to 25.35mm Backfocus

    This adapter is the critical link between your Lhires III spectroscope and a camera with a backfocus in the 21.35 mm to 25.35 mm range. Achieving the correct spacing is non-negotiable in spectroscopy, and this component creates a rigid, repeatable connection for accurate data acquisition.

    • Targeted Compatibility: Specifically engineered for the Lhires III, this adapter solves the mounting problem for a popular class of cameras, such as those with a nominal backfocus of 23 mm.
    • Simplified Integration: By using this adapter, you eliminate the need for custom-machined parts or unstable stacks of generic extenders, securing your camera directly to the spectroscope's optical path.

  • What is the purpose of the Lhires III adapter set for 23 mm cameras?

    This adapter connects a camera with a specific backfocus range (21.35 mm to 25.35 mm) to a Shelyak Lhires III spectroscope. It ensures the camera sensor is placed at the correct distance from the spectroscope's optics for a sharp spectrum.

    Which cameras are compatible with this Lhires III adapter?

    Any camera with a native backfocus that falls between 21.35 mm and 25.35 mm can be used with this adapter. While the title refers to "23 mm cameras," it supports the full specified range. You must confirm your camera's backfocus before purchasing.

    Do I need this specific Lhires III adapter for my spectroscope?

    You need this adapter only if your imaging camera has a backfocus within the 21.35 mm to 25.35 mm range. Shelyak offers different adapters for cameras with other backfocus distances, such as standard 17.5 mm C-mount cameras.

    How does this Lhires III adapter ensure I get a good spectrum of a star like Vega (Alpha Lyrae)?

    By precisely setting the camera distance, this adapter guarantees that the light from Vega passing through the Lhires III slit and grating forms a sharply focused spectrum on your sensor. Incorrect spacing would result in blurred spectral lines, making it impossible to measure features like the Balmer absorption lines accurately.

    Can I use this Lhires III adapter with a standard DSLR on my f/8 refractor?

    It is highly unlikely. Most DSLRs have a much longer backfocus (typically 44 mm for Canon EF or 46.5 mm for Nikon F-mount) and would not be compatible with this adapter. This adapter is designed for dedicated astronomy cameras that fall within the 21.35 mm to 25.35 mm range.

    Is this adapter difficult to install on the Lhires III?

    Installation is straightforward. The adapter is designed to thread or bolt directly onto the Lhires III's camera port, providing a secure mechanical and optical interface for your camera.
