My Skywatcher 150p on an EQ3-2 mount and OnStep STM32 Bluepill #EQ3
i want to say thank you for this great community, software and support. I learned much due this project and teaches me to go "OnStep" by step ;-) There is still some fine-tuning to do, but the weather is currently very cloudy.
I converted a Skywatcher EQ3-2 Mount and created some own and some modified 3D Printer files to fit my requirements.
