Make sure that you have colour processing selected on pg 1 of Regi.

Dave, I checked that but it was fine.
However, I'm wondering did I record the avi properly - I had Saturation up high and Gamma down fairly low.
Should they both be set near the max??
Also, when you are in registax, what size box do u select?
Where do u centre it? - on the Cassini division or between the rings and the planet itself?
Thanks,
Michael

Dont have all my setings to hand but I dont think that any of them are too far away from the centre. I'll post them later.

I normally use a box that will fill the image. This does mean that for large images Regi is quite slow.

I'll be down at Galway to do a workshop so maybe we could run it as some sort of a forum and discuss things as a group as oppose to me rabbiting on and on.

Sounds good Dave. Looking forward to that.
I tried further processing of the image in Photoshop so as to improve the colour saturation and add a tiny bit of sharpening to the rings. The dics is a bit more red and the rings have just a tint of blue. The encke minima is also just visible.
Is it any better or should I have left it alone? Anything else I should do to it?

Another possibility is that you "over waveleted". Sometimes this can cause the colours to saturate????? I normally use 6:1 and 5:1 and dont go above a vle of say 35. Ive added a data page here www.irishastronomy.org/user_resources/vi...les.php?folder_id=18 to try and get a standard method. Have I forgotten anything?

Michael,
Thats a great shot of Saturn there, I'm wondering how clear is any one of the frames before processing, Do you find that you need to run 1500 frames to get high quality or would you get the same with 100 frames???
Most pics I've taken are with about 100-150 frames, some as less as 20.

The second pic is almost likes like a starrynight pro image of saturn, very pastelle/solarized like ?? I prefer the first image you posted.
If you could post or send me 1 average unprocessed frame, just to compare start point with end point, I'd be very gratefull.
