Hi All,

Captured after a boozy night last night, when I got home at 2am.

Meade 10"RCX, Toucam for the colour, DMK for luminance. Don't know whether I had the 2x or 3x telecompressor in.

The Blue channel seems very blurry compared to the others when I split the channels in PS, any ideas anyone?

Cheers
Stuart

Hi Stuart, nice image.

Yes, it's normal for the blue channel to be the worst, due to the atmosphere scattering blue light.

cheers, Bird

Nice Saturn Stuart. Well done :thumbsup:

Where you able to capture any of Saturn's moons? :)

Nice Saturn image Stuart :)

I have a lot of trouble with Blue as well. Splitting into separate RGB channels prior to stacking as described in Mike's article http://www.iceinspace.com.au/index.php?id=63,306,0,0,1,0 helps a lot as you can apply different processing to the blue channel.

Next time, I'm going to try shooting a blue channel with a blue filter immediately after taking my main colour video. I guess I'm wondering if I focus on just the blue if I will get a better blue channel.

Have fun,
Doug
