Lads,
Absolutely , If I had planned it I would not have worked out. :roll:

To be honest, my pics aren't particulalry sharp, I use the laptop screen for focusing and this isnt the best at night time, I'll start using a PC monitor soon and it should make a differance as the angle doesnt matter.

Stephen, look at
www.qcuiag.co.uk/
and more specifically in the "members choice of images" section where you can really see what these webcams can do, like

Michael, I noticed your image looks a bit dark to me, again nothing wrong with your monitor, just the odd ball way mine is setup. I increased the brightness of my monitor to full, and it looks even better again, pity the GRS wasnt there, my images then look completely washed out.
You see, the reason I have the monitor the way I have it is because my video card came with a calibration program, and I for one believe black should be black on a monitor and not a faint shade of gray, just me been awkward. :)

Michael,
I went back and had a go at reprocessing the last image of the 5.



Its abit overprocessed in parts but more detail is visible.
I usually try to err on the side of caution when it comes to processing, funny how Europa comes our pale yellow/orange but ganymede is the colour you'd expect.

Dave,
There's definetly more detail there alright although, as you said yourself, it's just a touch overprocessed. If you record more frames in future it should help.
As for colour, I wonder what colour does Starry Night Pro show the satellites as :?:

Michael,
I was thinking more about the pics from voyager of Ganymede and Europa, ganymede seems to have that dark rock blue/purple/grey colour(darkest of the four), cant really describe it, well its not green/yellow/ orange or red ?!?
As for europa, if I remember rightly, it has a light sprinkling of orange/yellow sulphur dust on some of its surface, captured from dust ejected from volcanoes on Io, it also has whiteish areas. Starry night shows it way darker then I remember it!!

Anyway as for the the image , its wayyyyy over processed, lets be honest, sometime you need to draw the line between been scientifically correct (almost like a false image showing alot of detail) and been artistically correct (roughly what you'd expect ot see), I've seen very few pics that have both, I certainly havent made any pics that have both.

Your pics looks very natural but yet shows alot of detail, which is exactly what you want, this is a hard thing to achieve!
