My Saturn image looked a little washed out so I was wondering how do you get more color into the image?

I choose to image with an 11" SCT Celestron in this decade and do the other things, not because they are easy, but because they are hard......

Re: Saturn Colour
Well Carl, the image looks rather low in contrast - are you sure that you've optimised the camera settings to get the best dynamic range?
Using my Toucam with my f/10 SCT and a Barlow lens, I've been operating the camera at 1/25 sec with the gain set at about 70%. It's also worth playing with the "gamma" and "saturation" seetings on the camera menu.
And once you've finished processing the image with Registax, you can do some more adjustments of the colour balance in a photo-processing progam, such as IRIS:
To do this, I performed the following steps:

- Load the JPEG file;
- Digital Photo... RGB separation.. into r.pic, g.pic, b.pic
- Load r.pic file;
- Open the View... (L)RGB and move the R +1.5 and B -3.5 to to align the colours. Then save this file as temp.pic;
- Clean up the noise with Processing... Adaptive filter... Noise 5.0;
- Then View... Colour stretching... Stretch 0.0010, Intensity 2.50;
