ZWO ASI T2 to Canon EOS Adapter for EFW – Version II

DESCRIPTION
The ZWO T2-to-Canon EOS Adapter (Version II) enables astrophotographers to attach Canon EF (and EF‑S) lenses to ZWO ASI cameras via a filter wheel (EFW or EFW Mini). Featuring a male T2 thread (M42×0.75 mm), it screws into the filter wheel and provides a 17.5 mm backfocus, ideal for cooled ASI models. A removable 5 mm extension tube allows adjustment to 12.5 mm, accommodating uncooled cameras like ASI120, 224, 290, 178, and 385 

Made from black anodized aluminum, the adapter is sturdy, precise, and easy to install. It ensures optimal spacing and focus accuracy for wide-field astrophotography setups.
