Very nice. And interestingly, no real evidence of the darker equatorial band that was visible earlier this month.

Very nice image indeed.

From what I have observed the equatorial band is quite a bit more pronounced adjacent to the GRS, it seems to disperse as you move away from that side of the planet.

Cheers James. Yes, it is interesting that the darker band seems to have faded. There is always something new happening with Jupiter.

You mean the Ultra Penguin band?!

I took a video last night on my webcam and also experimented with the DSLR, I'll process and upload them later tonight.

Couldn't see the band in the unprocessed video.

BTW Great Jupiter image! Love those C14s. Just curious, do you spend much time perfecting the collimation?

Thanks for the comments.

I think am somewhat obsessive about collimation but the scope holds it so well that this is mostly just a matter of doing a star test at the start of each session. If it does need some adjustment, then I will spend 10 minutes of so sorting it out using a mono camera with an IR pass filter and of course Bob's knobs.

A much bigger issue for me is getting the thermal currents under control, a battle I thought I had won but I may yet have more work to do.

Cheers,

Chris

Stunning image - the detail is fantastic. Something perhaps to aim for one day after much training/practice on my part.

Chris,

That is a superb effort. Miles better than my efforts from last night. Not going to post them, I might after having a bit more of a pay with them. Think my focus was off and collimation was slightly out.

Here is a restacked-rework, aiming for a smoother image, possibly at the expense of detail!

Prefer that smoother natural rendition Chris, as a non scientist, when you lose that natural feel, in my opinion youve lost the mosty important thing about the beauty of planetary imaging. It Just comes down to art versus science. If something particulaly interesting was happening on the cloud bands that wasnt showing well, without pushing. Then yes maybe create two renditions for that reason. But i think most love the beauty element. Its a nice capture. The resize and more natural feel works better to my eyes. Good Job

Thanks guys. Having tried several approaches I agree that the smooth natural look is the best way to go. However, I am sure that my idea of a smooth natural image will change over time as I get more processing techniques and hopefully experience with better data under my belt.

One thing I would like to figure out is why my images looks so different on my work PC. That doesn't seem to be the case for other people's images!

Cheers,

Chris
