I've decided to try my hand at planetary imaging. As a long-time visual observer with my 22-year-old Skywatcher 127mm MAK, which is still going strong, I've recently upgraded my setup. I've added a Skywatcher AZ-GTI mount and a ZWO ASI 678MC USB 3 camera. While planetary imaging presents a whole new set of challenges, my setup is working well, and the tracking is solid. However, focusing on planets, especially when they're low in the sky, has proven to be the most difficult task.  Saturn represents quite a challenge, below are my attempts.  As I progress Im using different techniques.  A peg on the focuser works well, with a light touch each time.  I try to take at least 180 seconds on the target.  Focus on the planetary detail as much as possible, difficult for Saturn, and look for the gap in the rings during periods of stability.
