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.

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.
