why? astroberry is totally usable on a PC, the UI has so many features, and the "up" and "down" buttons are simply too small to use on a smartphone, or a mini tablet. So I start to investigate on a simple command line, or a "lite" version of UI with big buttons I use raspberry pi and old ASI120 as an example 1a. install ASI_linux SDK 1b. copy python-zwoasi from github , or simply 'pip install zwoasi' 2. extract or install under /home/astroberry 3. for testing purpose, copy the zwoasi_demo.py to ASI lib/arm7 directory 4. edit the zwoasi_demo.py file and insert os.environ variable as below: 5. save with another filename, eg, zwoasi_demo1.py 6. in terminal, run 'python zwoasi_demo1.py' first light photo: setting environment in python Steven Marple's blog how about FITS format? pyQt example
