Finally got some time on Jupiter tonight. I'm still not much of a planetary photographer but managed a nice single frame on my smart Dobbie and Cannon 550D. Io, Ganymede and Europa (Left>Right)
Also still playing with the Star Analyser on the iPhone. Interesting you can actually see the separate spectra of the moons. (note the different position angle due to a different camera and lens setup).
As its a long weekend its fun to have a bit of a play around with cameras, lens and such.
Here is the separated spectra, and bearing in mind here they were very faint and I am really just practicing technique here and having some fun - but you can tell some differences.
Io
Jupiter
Ganymede
Europa
Each was separated out in a thin slice and then had the vertical height changed to highlight the various light levels.
