Like Chris, I noticed the artefact's on the left side of the planet and rings too, but I see what you mean - increasing the black point would play havoc with the crepe ring.

Beautiful sharp images. Great colouration.

Thanks very much Mike.

Thanks for the explanation, it helps me understand what not to do to mine

No probs Chris, reckon its important to keep in mind the effects we can have on the actual image of the planet and the detail we are striving to resolve, with regard to attempts at cleaning up extraneous noise, from whatever source, that might be elsewhere in the field.

I also see the same (artifact or noise) in other images Asi. Reckon we both can recall seeing some images elsewhere that looked like fridge magnets due to the amount of processing that had been done to blacken the background right to the edge of the planet. I agree with you regarding the Moon, but I did note that on this particular night the Moon was very close and Saturn was also very close to opposition with the Seelinger effect quite noticeable. Collimation, a mute point really when looking at the hi-res detail present in the image which obviously wouldn't be there if there were issues with it. Roll on more good seeing Asi, onward & upward.

Good seeing is the word Trevor. I've not seen any for awhile now & thanks to that storm north of Cairns, it's not looking good for the immediate future - Fridge magnets - Was only looking at one of them on a certain site this morning lol. Some never learn!

And I've just seen Damians first Saturn image for this apparition...Good bye, 'fridge magnet'

I was checking my email this morning and saw Damian's latest masterpiece, such an unassuming young man and what an image. He certainly made a mockery of the low alt of Saturn. For years he has set the bar for the rest of us to aspire too, although I reckon Birds Jup from Exmouth is the best Jup I have seen.

A friend of mine in the UK, Dave Tyler, a lovely bloke, the elder statesman of planetary imaging in the UK and also extremely good at Solar imaging. Dave is 12 years older than me and has a similar background in engineering trades. Dave has been lamenting the fact that he will likely never see Saturn at a reasonable alt again in his lifetime. I sent Dave the merged R, G & B channels from the data posted in this thread to have a play with. Have attached what he sent back to me.

Naturally I have heard of Dave Tyler & have seen numerous images by Dave. He certainly hasn't lost the planet processing touch! Marvellous work on your RGB Trevor.
