My Primary Hobby is Astronomy and have quite some Equipment and also developped already some parts for focusing etc.
Now that retirement is near I want to invest more time and develop more useful prts for the astro Equipment and therefore I am asking myself what programable electronics would make sense.
Especially for stepper Motors and GUI to move telescope focusers as well as camera rotators and other stuff for remote adjusting or even guiders for tracking the Sun.
I have seen the Raspberry circuits, Arduino circuits, etc. like here in this page https://www.pololu.com/category/64/programmable-controllers
Taking into consideration the parts I want to move eg. stepper Motors mainly what would be the most Logical parts to look at in regards to programable or Controlling via GUI from a PC through USB or Serial Connection. I know some will say Serial communication is from the times of the dinosaurs but my experience is that Serial communication Fails less then USB communication
Thanks in advance for your comments and tips
