Jupiter’s galilean moons

Galilean moons are very easy to observe using some kind of instrument to get some magnification. With just a binoculars would be enough to spot the four moons of Jupiter. They are constantly rotating around Jupiter. Every day their relative distances and positions changes. Their names are Io, Callisto, Europa & Ganymede. They all have a similar size and brightness. When passing in front of the big planet, they cast a shadow over the gaseous surface of Jupiter. It is required a telescope to observe such events.

Here it is a picture I took tonight with a digital pocket camera through a 14mm eyepiece and a 150 mm newtonian reflector telescope with no-tracking system.

  1. What city are you taking your Jupiter photos from. Some of them I have not been able to match up in Starry Night 6. I was able to do so somewhat with this one though. http://tinypic.com/r/2r6letv/6

    Granted I know the software isn’t going to be 100% with actual reality but I had one that looked way off. Thanks.

      What image you couldn’t match up in Starry Night? My gear is not enough powerful to beat Starry Night for sure …

  2. It must have been this one: https://computerphysicslab.wordpress.com/2009/08/20/ganymedes-shadow/

    Just wondering what your city was so I could line it up with your photos to see how far off, if anything the software is.

    Side note. I got a skywatcher 130mm for my daughter a week ago and will try to do some photography with that.
