An evening with Saturn

As you may know Saturn is one of the solar systems gas giants and has ring around it. It is a distance of about 880 million miles from the Earth. If the "seeing" is good there is a lot of detail to be had.


Last night the "seeing" was poor meaning that the air was unsteady. This causes the image in a telescope to wobble, this give one second a good image and the next a blob. 


Here is a reasonable image (I have taken better) and a very poor one. This was around 09:30 last night
As you can see Saturn is a long way away and is a small image
Magnified you can see the rings. 




This is a moment of bad seeing, just a blob




This was taken with a different camera and telescope back in 2004.
Saturn's rings were more open so you get a bigger image.


I hope to get some better shots as Saturn gets higher and the decrease on the light of the Moon later next week.

  4. That is so poor, I thought that you could do better Mike.

    Cloudy one night, then the next I has someone here and yesterday was club, so no picture.

    Tonight I hope to go the Canterbury with Peter and take some images with the 14". Looking forward to it.
