So here is my latest project which is my mobile astrophotography device.
ASUS Tinker board. 2Gig DDR3 Ram Quad Core 1.8GHz processor running Ubuntu 16.04LTS. Kstars ekos with astrometry. See
http://indilib.org
All my hardware is connected to this device which I control remotely via VNC viewer from my laptop or tablet.
This is good because there are no cables connected between my imaging equipment and the client computer to trip over in the dark. Communication between the Tinkerboard and my laptop is via Wifi, so I can have my imaging equipment setup outside in the cold and I can control everything from inside my house in front of the fireplace.
The white device attached to the USB port of the Tinkerboard is a GPS adapter. When kstars/ekos is running (this is my astronomy software that controls all my imaging equipment), it automatically acquires GPS position, time and date which is then fed into kstars/ekos. This information is then used in the alignment module (or plate solver) in kstars to acquire your imaging targets (those pretty pictures you see).
The alignment module in kstars is very powerful, it has found every target i have asked it to find!!! Awesome.
See attached images and one image taken through this setup.
