Jon Rock showed how to use the mouse encoders.
Chris Rowland for source code on unique PWM values for the 2nd motor, and for many additional scroll commands.
Bob Segrest developed a microprocessor based encoder interface of great speed.
Chuck Shaw helped develop the field de-rotation system, spent time debugging the autogeneration of PEC routines, and has worked to develop a set of configuring instructions.
Pat Sweeney developed a PCB for the project.
Dave Sopchak contributed the iterative altitude offset algorithm.
Jean-Charles Vachon contributed the current limiting circuit.
Don Ware contributred the Flamsteed data sets along with NGC and IC1-5 data sets; and source code to read forwards/backwards through the data files; and the user defined hotkeys; and the polar alignment method for equatorial mounts; and more.
