First LRGB images

After some help from others in a previous post, I've managed to put together my first colour images. I went hard on the wavelets at the expense of noise, as I wanted to see how much detail I could squeeze out of these.
Seeing was pretty average, as was my tracking and focus. Still, I'm happy to have learnt a lot about GIMP and processing.

Cheers
Stephen

Hi Stephen.

If these are your first colour images, then it will be interesting to see your second!

Good effort.

Peter

looking good stephen, i think the first jupiter is the best by far, others a bit over done in the processing.

cheers

Hi Russell, yes I agree that there is some severe (and clumsy) over-processing, which was pretty much intentional as I need to find the limits of using software to compensate for poor captures... I think a lesson for me is to accept the limits of the captured data and work with that, rather than trying to drag out detail that really isn't there in the first place.

Hi Stephen, I think you pretty much nailed it on your first Jupiter. That's what a typical LRGB image looks like. The others as you've said are probably over-processed. I find a simple way to see if you're going too far is to keep an eye on the perceptual depth, remembering that the planets have volume which occupies a three dimensional space. Something you've captured well in your first image where the half tone (edge shadow) is present. The other two Jupiter versions lack this and appear rather two dimensional or flat. Remember with the gas giants is that they're free flowing gas balls that spin very fast, so it's OK if the details are not razor sharp. In fact a little softness sometimes looks more natural. We tend to identify things from their shape and inherent features and not by their small details. A good image doesn't always have to show every intricate detail it just needs to represent the subject and it's character which in this case you have achieved that. Well done!
