Moontrail with rpi
After quite a few successful attempts at imaging trails using rudimentary equipment, I decided to put my Raspberry Pi B+ and its camera to work and image a moontrail.
Past attempts include a set of sunrises at both solstices and at equinox, some sunsets, an analemma and some startrails. For these I used a Canon A800 enhanced with CHDK or a FujiFilm HS20EXR unmod. The CHDK was needed to access otherwise unaccessible options like manual focus, manual shutter speed and… well, an intervalometer. But this time a cron job did the work on my little buddy, the pi.
Below I describe the process in detail which lead to the final pictures. If you wish to skip it, click here.
