Images of Io and its shadow crossing Jupiter (singing "Io and Myo Shadow") on 28th Dec 2013.
All images are made using IR pass for luminance, Red filter, Blue filter, Green is synthesized from a combination of the Red and Blue images (although I prefer to synthesise rather than synthesize). Al taken on 8" Newt at F22. Time stated for each image is UT on 29th December.
First image suffered from warm telescope issues (tube currents) last image suffered from Spode's Law (bloody clouds).
