Cylindrical metal spacer for SBIG 8300 camera filter wheel replacement

SBIG Astronomical Instruments

SBIG Filter Wheel Spacer CA-FWSPACER for 8300 cameras

SKU CH-JBC2-788HA

A spacer matching FW5-8300 or FW8-8300 thickness replaces the filter wheel when integrating an OAG-8300 with color STF cameras

  • Optimizes astrophotography setups for color STF cameras
  • Replaces filter wheel when integrating OAG-8300
  • Matches FW5-8300 and FW8-8300 thickness precisely
  • Precision-crafted for seamless camera fit
  • Enhances imaging performance with reliable integration

Purpose and Compatibility

The SBIG Filter Wheel Spacer CA-FWSPACER is built for colour STF cameras using the 8300 platform. It replaces the FW5-8300 or FW8-8300 filter wheel when an OAG-8300 off-axis guider is installed, keeping the optical path length unchanged. Astrophotographers who want to add guiding without a filter wheel will use this spacer to preserve focus and back-focus integrity.

Setup Verification

Confirm that your camera is a colour STF model designed for the 8300 series and that you are fitting an OAG-8300 unit. The spacer duplicates the exact thickness of the standard filter wheels, so no additional shims or adapters are required. Ensure the mechanical interface on your camera matches the FW5-8300 or FW8-8300 pattern before ordering.

Function and Benefit

By substituting the filter wheel with a precision-machined spacer, the accessory maintains the camera's original mechanical register while allowing the OAG-8300 to sit at the correct distance. This preserves imaging performance and avoids focus shift that would occur if the filter wheel were simply removed. The result is a stable, light-tight connection ready for guided deep-sky sessions.

Questions about this item

What comes in the box with the CA-FWSPACER and do I need to buy the OAG-8300 separately?

The spacer is sold individually. The OAG-8300 is a separate accessory and is not included with the spacer.

How do I know this spacer matches my FW5-8300 or FW8-8300 filter wheel?

The spacer is manufactured to the same thickness as the FW5-8300 and FW8-8300, so it directly replaces either wheel in the optical path.

Will using this spacer instead of a filter wheel change the back-focus distance on my 8300 camera?

No. Because the spacer matches the filter wheel thickness, the back-focus distance remains unchanged when you swap the wheel for the spacer.
