A really old Jupiter shot:Jan 11, 2001

Recommended Posts

Just to show how far we have come, this is probably my best analog shot of Jupiter, taken with my Contax RTS-II on Fujichrome 400 slide film pushed to 800 ASA, using the C8 with eyepiece projection using a Celestron10mm Plossl. Seeing was stunning, that evening, and 2s to 3s exposure managed to capture the Great Red Spot, and even some details in the bands. Compared to the shot taken with a webcam on 8 October, 2010, there is just no comparison.

I think you are under selling the 2001 image.............. had the same computer power been available then you would have pulled out a lot more detail I'm sure. Even as it stands it's an image that appeals to me.

Anyhow,here's a very quick tweak in Photoshop just to illustrate my point.

True, but the signal to noise is much worse. Better processing helps, but you start blowing up noise all too easily. Subtle detail like the "baby red" spot and many white oval spots are not captured in the former image. The seeing in the latter image was actually worse.

Thats a good image using the methods described above, i agree perhaps under selling is correct. Simon.
