Deep Sky Imaging:

Best imaging for this month is between the 4th and 15th with skies being darkest around the 9th.

The summer constellations are still dominating the night sky with the summer triangle being overhead around midnight, all of the objects mentioned last month are still well placed for imaging.
M31, The Andromeda Galaxy is now rising earlier enough for imaging as is M33, The Triangulum Galaxy.
