Jupiter 27 August

Images of Jupiter from 27 August. For my Watec 120+ and my Newton 10" the red channel is very close to the gamma limit, and it is difficult to achieve a natural-looking color....

Nice detail there Pelu.

You must have been imaging for quite some time to get that much rotation in Jupiter, well done.

Try adjusting the level of the RGB channels separately in Photoshop. Also the image looks a bit oversharpened, if you back off on that a bit it'll give it a more natural look.

Paul Haese has published an excellent guide to planetary image processing, I recommend that you read it. I learned a lot from it.

Cheers
Stuart

Some very nice detail in these images Pelu,

I think you have been a little heavy handed with your processing, it looks like you have nice data but I think you will find that the better your data the less is the processing required.

Have a look around on the internet, there are many top planetary imagers that have posted how they do their stuff. Anthony Wesley, Paul Haese, Donald C. Parker to name a few. Here on IIS in the Projects & Articles section Mike Salway has an excellent article on planetary imaging. Have a look at the different methods employed by these guys and then work out what best works for you and your imaging system.

Regards
Trevor

Great stuff Pelu - looks like you had some pretty nice seeing, but agree the processing is a bit heavy handed.

I'm sure you'll be reworking the data for a few days to come! It's always the way when you get a nice night of seeing.

Thank you all.

Yes, I must to forget how I process my Black and White images...
Simply moving a bit the central cursor in Photoshop Levels is much more enjoyable to watch.
