Jupiter and Io ( Moon of jupiter)
Jupiter is the fourth brightest object in the sky (after the Sun, the Moon and Venus). It has been known since prehistoric times as a bright "wandering star". But in 1610 when Galileo first pointed a telescope at the sky he discovered Jupiter's four large moons Io, Europa, Ganymede and Callisto (now known as the Galilean moons) and recorded their motions back and forth around Jupiter. This was the first discovery of a center of motion not apparently centered on the Earth. It was a major point in favor of Copernicus's heliocentric theory of the motions of the planets (along with other new evidence from his telescope: the phases of Venus and the mountains on the Moon). Galileo's outspoken support of the Copernican theory got him in trouble with the Inquisition. Today anyone can repeat Galileo's observations (without fear of retribution :-) using binoculars or an inexpensive telescope.

Excellent picture Mohammad! Jupiter is sharp, detailed and colorfull. Big Red Spot well visible, same as Io. And this dark spot on planet's surface - is this shadow of moon?
Great post, I like it very much!

Amazing ... for the information that the photograph conveys and serving as an example that mere amateurs like us could take pictures like this. Thanks for the notes too.

Mohammad, needless to say this is a very nice idea.

Excellent and clear presentation. I also enjoy composition and this huge darkness around the planets.

WOW! Incredible photo!
So you stacked 300 frames to get this...
I can say from experience, astrophotography is no easy feat. This is an awesome picture!
