I agree with the advice to remove the reducer. I mean, it isn't even advice, it's an absolute necessity. Imaging at 2032mm to start would be fine, but 1200 won't get you much.
However, it should be easier to focus at 1200 than 2032 (or higher). When you focus, how do you do it? Do you have an electronic focuser? Either way, you should confirm that you have enough travel to go through focus. At focus, on Saturn in good seeing (though maybe not at 1200mm), you should see Cassini's division. With varying seeing, it may go in and out. I find Cassini's is a nice feature to get close to focus (before shifting to cloud bands). If you aren't seeing Cassini's on the live view, you either aren't in focus or the seeing is very poor. Or, I suppose, you might just not have the focal length.
You mention DSO imaging. You aren't by chance focusing on a star with a Bahtinov mask and then leaving it unchanged at the planet are you? That's a pretty common error moving from one type of imaging to the other.
Also, the question about sharpening is a good one: Have you used wavelets or deconvolution to sharpen?
Planetary imaging is very different than DSO imaging. Most of what you know in one is marginally useful, or even sometimes harmful, in the other.
Hang in there. You have a long season of the two big ones (and then Mars!) still ahead of you and the reward is well worth it.
