So low in the sky but still beautiful to behold...

That looks like your best Saturn to date Duncan. Great stuff.

Is it possible to slightly reduce the graininess or have you already done as much as you dare?

Carole

PS: I tried a couple of iterations in PS filter noise/despeckle and it got rid of the graininess without affecting the image.

Saturn is really difficult to get this year so that's not a bad result. A night with perfect seeing would make all the difference!

Thanks Carole, itvwould be nice if it were sharper. If I reduce the graininess then the small amount of feature detail goes too since the noise reduction is essentially smoothing.

Well done!
Looks quite good.
I tried and failed.
