PinPoint Astrometric Engine 6.1
Now With All-Sky Plate Solving and UCAC4 Catalog

Welcome to the web site for the PinPoint Astrometric Engine, a programmable engine that provides sensitive, robust, high-speed research-grade astrometric image processing for FITS files from any camera. A set of point-and-click tools (Visual PinPoint) for fast mass plate solving and survey-level asteroid and supernova hunting are included.

PinPoint 6 has built-in all-sky plate solving, eliminating the requirement for approximate image centerpoint coordinates and plate scale at the cost of additional time. An internet connection is needed for this. PinPoint automatically uses the cloud solving service of Astrometry.Net to find its initial solution, then it takes that as the starting point for a full PinPoint solution including distortion mapping. This is all automatic to you and to client programs that embed the engine.

Typical uses include plate solving which gives precise pointing to telescope mounts, asteroid and comet searching, high-precision astrometry (detection and measurement of positions), and supernova hunting. The package comes with Visual PinPoint, a point-and-click Windows program that has automated tools for hands-off asteroid and supernova hunting with optional blinking for validation. You can use Visual PinPoint with any FITS or POSS/DSS images.

PinPoint is used as the plate solving engine in many astronomy applications out there, including Diffraction Limited's MaxIm DL and MaxPoint, Weber and Brady's FocusMax and PoleAlignMax, CCDWare's CCD Autopilot, and of course our own ACP Observatory Control Software.
