After an awful May...

Yesterday we have had a clear night after one month of continuous rain. I decided to watch Saturn that is yet near to the opposition. I have tried to shoot it with different filters (red, yellow and green) and have found that the best contrast is obtained with the green one. Here the picture with the technical details.

Celestron C8

CCD Imaging Source DMK31AU03.AS Monochrome with a green filter.

1200 frames at 1/30 sec elaborated with Registax.

Then I changed the camera, connecting the Canon reflex to the telescope, and pointed the M13 Hercules globular. This is the result.
