Details:
Fighting high clouds, two breaks occurred between: 7:09-7:34PM and 9:09-10:31PM MST where I tracked the Rock Comet 3200 Phaethon with one minute exposures @ f/5.0, iso 1600. using a Nikon d7100, Nikkor 180mm f/2.8 lens mounted in an Orion Sirius drive.

This object was ~11.3 magnitude moving about its own 5 km diameteer every minute. The two tracks can be seem near the center of this stacked image (integrated 83 raw frames in PixInsight).

The very bright star is Capella.
