Jupiter – moon shadow

Following on the experience from last Saturday, I decided to try and capture more of Jupiter on the Monday. It was great that the skies were very clear, although the seeing seemed to be very variable that night, with brief moments of great seeing.Having learnt from my previous experience, I used a gain of 300 and shutter speeds which were considerably faster than before – about 20-25ms for the RGB videos, and about 8ms for the Luminance channel. Hence I ended up with many more frames from which to choose from.

It was great that around the time I was capturing Jupiter, two of its moons Europa and Io were moving in front of Jupiter and hence casting their shadow onto Jupiter’s surface.

Again I managed to capture many RGBL series to stack into images. I ended up with 12 frames of Jupiter to produce the animated GIF below.Jupiter_LRGB07032016a_pipp

In hindsight, I would probably have taken shorter videos perhaps 30 to 40 seconds for each channel, so stacking them would be easier. And hopefully in future I will be able to capture even more detail with my larger telescope.
