Thanks for the comments. I'm using GIMP. I'm getting better with it all the time. I've just posted a second image taken a few minutes later where I've got the colour heaps better. Still could use work though.

I know you used to push me to use 5fps when I was starting with Saturn, but I always get much better results at 15fps on Jupiter. It lets me capture more frames before the planet rotates too much which allows me to compensate for the compression with stacking.

I then set the longest exposure time available at 15fps and adjust the gain until the histogram is at about 220. Much like you told me when I started.

I use custom white balance (as auto makes the colour balance fluctuate wildly).

As I said, I found the conditions shocking until 5am. I also got into using a blowdryer to clear the dew. The scope was absolutely dripping by 2am.

I wonder if the secret to good seeing in Brisbane is to get up early and start imaging around 5am rather than staying up late.

Have fun,
Doug
