Extendable camera adapter SW-8005 OEM, 2 inch diameter, adjustable length

Extendable camera adapter SW-8005 OEM is a 2 inch diameter, adjustable-length adapter designed to connect cameras or imaging devices to optical instruments with 2" fittings. The adapter provides a variable extension tube that enables fine adjustment of distance between the camera sensor and the optical interface, allowing improved focus control and framing for applications such as astrophotography, digiscoping and general imaging with telescopes and spotting scopes.

Advantages

The adapter's 2" diameter tube offers broad compatibility with common eyepiece holders and accessory ports. Its extendable design allows incremental length adjustment to achieve precise backfocus and image plane alignment without the need for additional spacers. The construction provides a stable mechanical connection to reduce flex and maintain optical alignment during imaging sessions.

Suitable for

• Astrophotography with telescopes requiring adjustable backfocus
• Digiscoping with spotting scopes and compact cameras
• Connecting mirrorless or DSLR cameras to 2" optical accessories
• Laboratory or field imaging where variable extension is needed

Key specifications

• Inner diameter: 2 inches (compatible with standard 2" fittings)
• Adjustable length: extendable tube for variable extension and fine positioning
• Material: rigid tube construction to provide stable connection (metal or composite finish)
• Mounting interface: designed to mate with standard 2" eyepiece holders and accessory ports
• Mechanical features: smooth sliding adjustment with locking mechanism for secure positioning

How to use

Insert the adapter into the 2" eyepiece holder or accessory port of the optical instrument until it seats securely. Attach the camera or imaging device to the outer end of the adapter using the camera's compatible mount or retaining collar. Adjust the tube length by sliding the extendable section until the image reaches the desired focus and framing on the camera sensor, then engage the locking mechanism to secure the position. Make incremental adjustments while observing the live view or focus aids until optimal focus and field coverage are achieved.

Usage recommendations

For stable imaging, ensure all connections are tightened and use a tripod or mount to support the optical instrument and camera. When performing precise focus tasks such as astrophotography, make small incremental adjustments and verify focus with high-magnification live view or focus-assist tools. Protect the adapter interior from dust and moisture when not in use.
