A Practical Astronomy talk given to the April 11, 2014 meeting of the Austin Astronomical Society. Learn about the basics of low cost planetary astrophotography with the Raspberry Pi a credit card sized Linux computer with a 5MP camera module that costs less than $70. Ultra small networked computers like the Raspberry Pi are being used by amateur astronomers in many ways. Details of the Astro RPi prime focus camera are described as well as sensor selection and optical and processing techniques to get the most out of your telescope images.
