There are some things we could do to enhance the project.
- To enhance portability, we can configure the Raspberry Pi as a WiFi access point. This would create a local wireless network so you can control the system with an iPad with a VNC Client installed.
- Modify lowlight.py so you can specify the shutter speed and ISO with options.
- Build a small LED light and use it for light painting.
- Use velcro and piggyback it on a motorized telescope, then do astrophotography.
Use your imagination!
