Search Less, Observe More
Precision Plate Solving for Every Observer
PiFinder’s plate-solving technology means there’s no need for encoders or complex star alignment. Just power it up, select an object, and get immediate push-to guidance — from dark sites or light-polluted city balconies.
Mounts like a finder, works like sophisticated DSCs, and includes powerful observing tools. Get more out of your observing time, with PiFinder!
Encoderless Pointing and Push-To
The PiFinder takes photos of the sky and uses them to determine exactly where your telescope is pointing with no setup or user intervention… up to 20 times a second! Between exposures a sophisticated accelerometer provides real-time updates to drive on-board star chart generation and easy push-to guidance. Installs like a finder, performs better than digital setting circles!
A self-contained observing tool
Everything you need, right at the eyepiece! The PiFinder will determine where you scope is pointed as you move around the sky and display an interactive star-chart centered on its position. You can search and filter a catalog of over 20,000 objects to observe and see how each object will look through the eyepiece. Once you’ve found a target the PiFinder guide you with easy push-to guidance… it can even log your observations.
