The more that you can tighten the parameters of your shots the more that you can change camera settings to optimize the taking of the photos and the quality of the photos. The most immediate photo targets that came to mind is the middle position of the stabilization slider on the 200-600mm lens.
Around 1977 I bought my first camera, an Olympus OM1n. I bought it to connect to my telescope for astrophotography. My thought at the time was that the photography can't be that hard. Getting a telescope to track accurately for a hours at a time. Little did I know.
