You seriously saying this is poor???? Looks pretty darn great to me! love your processing with moons galore! I can't even get a proper cassini with my Dob in the UK. Great job!

That is NOT poor seeing, and a stunning Saturn for a 10" scope. Nice work.

It is a beautiful image. There is lovely banding around the surface of the planet and the color is rich. Processing of the image is well done.

About detail...Does anyone else see these features? I see traces of Encke Division. I'm hoping Encke will be easier to see, as Seeliger effect occurs. But, it might have an opposite effect. And, the Maxwell gap appears to be there if I'm not mistaken. That is something I have not seen in ground based images of Saturn. Spots? Harder to see...I'll leave that to Trevor. Hexagon is obvious.

Thanks for sharing, ZuoZhao.

for a DOB10,I think it is good. The seeing seem not bad. But may be the limit is 10",not my skill.

Wonderful image ZuoZhao! If I can come close to this (in the morning I hope!)., I will be well pleased!

DOB10 can capture six of them, but TT out of sight. I don't take it in. Due to trace not well, only short exposure can make.

That is my confusion. Even a heavy sharpening, Encke not clearly. And many spots of noisy. So I give little sharpening to remove all these effects,which may be some mistaken with sharpening.

It is hard to control and remove noise without sacrificing detail. It is a delicate balance, not a mistake. You are not alone, my friend. Not to worry, your image is very impressive.

No way we'd get that 53* North , even in perfect seeing

Wonderful image. I like how the brightnesses and colors of the moons are all different.

ZZ, excellent image! Very nice banding and color. Capturing 5 moons is impressive. Try projecting the north polar cap, it looks hexagonal to me. Thanks for posting

Regards,
Steve

A very nice image of Saturn ZuoZhao. Nicely processed and a top job with the colour balance.

I am not aware of anyone on our planet that has imaged Saturn more than me over the last 5 years and I say to you that this is far from a poor image. There is considerable detail to be seen within it. You just have to be aware of how to detect it.

Movement is the key. If you open your image within a smaller window than your screen in something like IrfanView( which is freeware), then drag it around to and fro across your screen, the fine detail within the NEB and along the edge of the Great Storm Remnant will become obvious. There is a small dark spot on the upper or Southern edge of the storm remnant ( the bright whitish band toward the bottom or North Pole. If you concentrate on that dark spot, while still dragging your image to and fro across the screen, you will notice above it in the NEB and just a bit further to the right or Following side, a reasonable well defined soft bright (white) spot.

You also have the C or crepe ring nicely defined. Often it is lost due to gross over sharpening.

So, in summary, you should be well pleased with this effort.

Regards
Trevor

PS: Noise is random but true detail is constant which is why animating a few images taken, over perhaps, an hour, will always define the difference between noise & true detail.

Excellent point, Trevor. And, excellent tip for getting the most out of Saturn's detail. And, such a simple method.
