A hazy evening doesn't sound like the best conditions for taking photos of a planet like Saturn, but if you can cope with the reduced light level it can produce good seeing. These are the conditions I had on 5th September. Saturn is still pretty low down in the murk (20 degrees), but it is getting better each year. It was around opposition, so it is more less face on. (No significant shadows on the rings) I took a dozen sets of 2000 images, and chose the best 300 images in each set to stack. I then stacked the 12 stacked images. This is cheating of course, since the rotation of the planet will smear any fine detail, but I was sure there wasn't any such detail. It is worth it to get a less grainy image. You couldn't get away with it with Mars or Jupiter, of course.
Celestron CPC 11" Using Canon 500D with 'Backyard EOS'. Stacked with 'Registax'.
The cooler, blue hemisphere contrasts nicely with the other, brown hemisphere. The Cassini Division is a bit messy on the image, probably due to some excessive wavelet sharpening on the original stacked images.
It is worth considering that the rings are rapidly tilting towards us, and will be edge on in less than 2 years. Observe those rings while you can!
All these things contributed to rather dim looking frames. I used a high ISO setting to brighten it up again, but of course that adds 'grain' to the frames. I guess the relatively large number of frames smoothed that out quite a bit. I hope you manage to bag Saturn at some point.
