The adapter allows connecting Schmidt-Cassegrain accessories, like correctors, off-axis-guiders, etc., to focusers with 2" receptacles. The adapter mainly makes sense if a 2" focuser is used with an SC telescope but one wants to continue using SC accessories.

• The TS2A-SCA adapter has a 2" filter thread (female) at the telescope side which accepts mounted 2" filters.
• The 2" barrel is smooth and therefore optimiued for modern focusers and adapters with compression ring. Jamming and tilting can be excluded.
• A flange separates the SC thread from the 2" barrel, thus providing a clean stop.
• With 8.5 mm length, the male SC thread is extra long, thus you can use T2 or 1.25" adapters with retaining ring.
• An anti-reflex thread prevents from unwanted reflections.
