The all-new PiFinder rev4!

A bigger screen, more than twice the battery life, and one design that fits every scope.

Fully assembled, tested and ready to use — just add to any telescope for precision pointing, easy push-to and a full suite of observing tools. The PiFinder photographs the sky and always knows exactly where your scope is pointed: no encoders, no star alignment, no phone required.

Fully assembled and ready to observe

1.91" OLED display — 62% more viewing area and nearly twice the pixels of v3, same size device

Built-in battery: over 9 hours of observing, with on-screen battery level

Integrated soft power button with clean shutdown — and charge while observing via USB-C for unlimited runtime

One configuration for every scope: converts between left, right and straight in seconds, no tools

New directional joystick alongside the familiar keypad, plus a speaker for audio cues

Pre-installed software — open source and universal across every PiFinder generation

Same proven imaging and plate-solving system as v3

One PiFinder, every scope. Whether your focuser exits left or right (most dobs and Newtonians) or out the back (refractors, SCTs), the rev4 adjusts to fit in seconds and if you change scopes down the road, your PiFinder changes with you.
