The loose open cluster NGC 7243 in Lacerta. It is in a rich field and hard to distinguish from the field here but visually it looks more impressive in the eyepiece. The bright star at left is Alpha Lacertae. North is up in this field. This is a stack of 5 x 8-minute exposures with the Canon 5D Mk II at ISO 800 through the Astro-Physics Traveler apo refractor at f/6 with the Hotech field flattener. Taken from home on a very clear night August 1, 2019. Star spikes added with Astronomy Tools actions.
