A real-time Right Ascension (RA) compensation calculator.
Given a target RA and calibration date this code displays the compensated RA value for a telescope with a fixed RA-aligned axis.
It is designed to run on a Raspberry Pi Pico with the assistance of I2C-based devices that consist of a pair of dot-matrix displays, non-volatile memory in the form of a FRAM, and a Real-Time Clock module.
It's essentially a handy, portable, real-time implementation of the 'trick' described in my related repository: -
Which can be easily assembled on a prototype breadboard base that provides seating for all the devices and some handy buttons: -
