SKY90 CFW10-ST CCD Adapter

The Takahashi SKY90 CFW10-ST CCD Adapter (model TCD0018L) connects SBIG ST-series CCD cameras equipped with CFW10 filter wheels to Takahashi Sky-90 refractors or FSQ-105 "New Q" reducers. This precision-engineered adapter features male T-threads on one end and 55.9 x 0.75mm threads on the other, with carefully calculated 41.2mm spacing to ensure proper optical alignment and backfocus for wide-field astrophotography and CCD imaging. The adapter's robust construction provides reliable connections for professional-grade astrophotography setups using legacy SBIG ST-series cameras.
