July 2017One of the fun things I did as a visual observer was to observe the Geostationary Satellites. From Northern California these are positioned quite close to Messier 11. Of course, Messier 11 moves as the sky rotates. The satellites either appear as stationary dots with the stars moving past them (view from a dob) or as retrograde dots (from tracking mount). As long as you view them close to astro dusk they are quite easy to see visually.
