I use higher gain 50-70% and then balance the exposure to get a reasonable image but not too overexposed. Remember the lower the exposure the faster the frame rate. The faster the frame rate then the larger the number of frames and the likely hood that you will have sufficient good frames to make a good image. You use a 2x Barlow and so do I but I use a 10" SCT at 2500mm FL yours you should use at least a 5x Barlow but then the image is dimmer and your frame rate goes down. No free lunch. Your main problem as well is a good camera and for about $300 an ASI120mm is really great. You could get a ASI120MC the colour version but the resolution goes down. Again no free lunch.
Read sSalways planetary imaging guide on IIS as its a good intro.
Hope this helps

Some pretty good advice in here.
I have a 2x Barlow (with my telescopes aperture being 130mm). I also have a extension tube as well. What would be the max power I could get to capture Saturn at a decent size?
