ASTON T-Adapter MAK/SCT Mount for Prime Focus Astrophotography

Prime focus astrophotography adapter for Maksutov-Cassegrain and Schmidt-Cassegrain telescopes, enabling direct attachment of DSLR or mirrorless cameras via a T-ring. Precision-machined from anodized aluminum with a blackened interior to eliminate internal reflections and maximize image contrast.

Advantages
