The PrimaLuceLab 33 mm and 37 mm adapters are precision-machined interface rings designed to extend the compatibility of the SESTO SENSO 2 robotic focusing motor to external focusers that use larger diameter shafts. Out of the box, SENSO 2 supports focusers with a 25 mm shaft; these adapters allow secure installation on focusers with 33 mm or 37 mm diameter shafts — commonly found on high-end focusers like 2.5″ / 3″ FeatherTouch (33 mm) and 3.5″ FeatherTouch or FSQ-130 (37 mm).
Key Features:
-
Shaft Compatibility:
-
33 mm version: for focusers with 33 mm diameter shafts.
-
37 mm version: for focusers with 37 mm diameter shafts.
-
-
Build Quality: Machined from durable, high-precision materials to ensure a stable, rigid connection — critical for maintaining focus accuracy.
-
Long Bushing Included: Each adapter package includes a longer bushing (shaft sleeve) that bridges between the focuser shaft and the flexible drive shaft in the SESTO SENSO 2, enabling reliable mechanical coupling.
-
Installation: Replaces the coarse and fine focusing knobs on your focuser (macro & micrometric). After removing them, the adapter mounts directly to the focuser. Then SENSO 2 is connected using its standard collar and the provided longer bushing.
-
Compatibility Note: These adapters are only compatible with SESTO SENSO 2, not the first-generation SESTO SENSO.
-
Package Includes: Adapter ring, longer bushing, mounting screws, and installation guide (usually in English and Italian).
-
Ideal For: Astrophotographers or telescope users who want to motorize focus on focusers with non-standard (larger) shaft diameters without resorting to external brackets.
