Hi Houghy, Jupiter is relatively bright in IR as it is a net emitter of energy, that is it emits more energy than it absorbs from the Sun. Isolated hot spot have been recorded previously that were associated with impacts such as SL9 and the Bird Strike. Lightning occurs within the atmosphere of Jupiter so I suspect that very active storms my also show up well in IR. If Io was in transit it would definitely be extremely bright in IR. I would think, intuitively, that reflected light would not be bright in IR, thinking about how air born IR cameras show up body heat very brightly in the night here on Earth.

I will look forward to your results with it on Saturn.

Thanks Lester, your experience with Mars would seem to support the documentation supplied by Astronomik on the characteristics of this filter.
