Everything you need for a night of observing right at your eyepiece. The PiFinder combines positioning, catalog filter/search, chart display and logging!

Spend your valuable observing time… observing! When you turn on the PiFinder the GPS and plate solver go to work. No multi-star alignment, no sky modeling — confirm one star and the PiFinder points the way all night.

The PiFinder database contains nearly 150,000 objects from 21 catalogs — every NGC, IC and Messier object, plus the complete Washington Double Star Catalog. Use the built-in keypad to search and filter by object type, magnitude and current altitude to find the best targets available!

Find any object in the sky with ease! Clear and legible directions will guide you right to your target and high-precision plate solving will put it right in the center of the eyepiece, even at high power.

Fully adjustable OLED display and keypad backlight allows for dark adaptation and ease of use. No matter what you are doing with the PiFinder you can always adjust brightness with a keypress.

Verify and find objects quickly with catalog images showing objects and star fields oriented just as it is in your scope. Switch through your eyepiece collection to see the actual object scale in each FOV!

The PiFinder serves as a wireless access point so you can connect your tablet, laptop or phone to use its precise pointing information in applications like SkySafari!

The PiFinder is fully open-source with complete designs and build guide online. There is a full list of parts you can source yourself, or purchase a kit or assembled unit!
