Titan, Tethys, Rhea, Dione, Iapetus are five bright moons of Saturn, the ring planet in our Solar system. They can be observed through amateur telescopes with at least 100mm (4 inches) of aperture. The following picture was taken through a 5 inch telescope, a Celestron NexStar 5 SE XLT. It is an image composed of 84 single subframes of 1 second of exposition each one.

It was taken on 2011-03-06 02h10mUT using a DBK 21AU04.AS Imaging Source CCD camera. Planet was recorded in a different exposition through a video stacked (shift and add) using Registax free software.

Check out the JPL simulation matching the picture above.

Sharing raw footage of Jupiter and Saturn

On 2011-02-06 I  took some videos of Jupiter and Saturn through a (4 inch) 102mm apochromatic refractor telescope. Applying Registax I got the results of the picture.

I’d like to share these two videos with anybody interested in playing with them:
