Abstract :
The new concept of reprogrammable digital circuit implementation for an auto-guiding system is shown in this paper. It is dedicated to astrophotography and operates with popular CCD webcam and ST4 compatible equatorial mounts. This idea was verified by a MATLAB model which was used to test all procedures and data conversions. Next the circuit prototype was implemented on an Altera MAX II CPLD device and tested. The project was designed also for amateur astronomy so costs, user friendly configuration and maintenance are very important factors which were taken into consideration.
