AutoGuider for a telescope using a Raspberry Pi, with RPi camera (v1 or v2) or suitable webcam.
This script was developed to auto guide a telescope through a ST-4 port using a Raspberry Pi (Pi2B/Pi3B/Pi3B+/Pi4 recommended) and a suitable interface.
The interface can be an opto-isolator, relay card available for the Pi, eg Seeed Raspberry PI card, PiFace Relay Plus card or any 4 relay card you interface.
The relay cards can also be modified, different wiring to scope, to auto-guide other scopes eg Meade LX-10.
It can also be interfaced to scopes via an Arduino Uno, via USB. The Arduino Uno can also be controlled by a PC using software such as PHD. Details can be found under the Arduino-Uno-AutoGuider repository.
The Pi can also control a Canon DSLR, via an interface, to allow long exposure photographs.
Please take care when interfacing your telescope or camera. At your own risk.
