I'm pushing mine up over 900-950 as well, sometimes over 1000 especially for the blue channel. It's making the image very grainy, but with the transparency so poor, and Saturn so dim at the moment, it's the only way to get a bright enough image without getting more aperture, or using a slower shutter speed.

Not that I know of - I tried it a few weeks ago when I was only able to capture a red and green channel before clouds came over and I wasn't able to capture blue.
I combined the red and green to make a synthetic blue, and then tried to combine them into an RGB image - it sort of worked, but the colour balance was horrible and I just couldn't get it to look right - so I gave up.
