Key Features

Advanced 3G5E Petzval APO Design

Our 3-group, 5-element triplet Petzval APO structure ensures superior optical consistency and portability compared to complex 6-group all-separated designs—delivering exceptional sharpness with a simpler, more reliable form.

Built-in Flat Field for Perfect Frame

Featuring a native flat-field design, it eliminates the need for external correctors—saving cost and setup time while providing edge-to-edge star clarity right out of the box.

Integrated Focus with EAF Readiness

The one-piece helical focuser comes pre-equipped for Electronic Auto Focuser (EAF) mounting—enabling smooth, automated fine-tuning during imaging, unlike separate manual focus systems.

Universal Compatibility & Easy Integration

Designed with standard threaded interfaces and ample back focus, it seamlessly connects to DSLRs, astronomy cameras, and filter wheels—streamlining your imaging train without adapters.

Robust Build for Demanding Conditions

With an all-metal body, protective lens coatings, and sealed construction, it performs reliably in humid or dusty environments—made for lasting performance under the stars.
