Try Subaru Image Processor Makali’i

• Download Makali’i (means Pleiades in Hawaiian) from http://makalii.mtk.nao.ac.jp/index.html.en

• Remember to register your software.

• Then open up a set of Saturn images.

• Set up the contrast so you can see the moons.

Blink to watch the ‘seeing’ change the quality of the images.

Sometimes it looks like a moon is double!

‘Poor seeing’ creates kind of a double exposure.

Seeing: Different temperatures and densities of bubbles or layers of

air in the atmosphere refract the light first this way, then that way.

Hubble Space Telescope is above the Earth’s atmosphere...

No worries about ‘seeing’ conditions out in space!
