Comet 226P/Pigott-LINEAR-Kowalski. Exposure: 20x30s. Date: 2016 October at 04:45 EDT (midpoint).  The faintness of the comet made stacking somewhat problematic (hence the slight curve to the star trails).  Stacking on the stars (with the comet trailed) looks nicer.  The comet was 2½° N of M1 at the time.

Comet P/2010 H2 (Vales). Exposure: 18x30s.  Date: 2016 October 14 at 05:32 EDT (midpoint).  The comet was in the top of the sickle of Leo at the time.
