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.
Helix Nebula NGC 7293 with 4-inch Astro-Physics Traveler apo refractor at f/4.5 with telecompressor, and Canon 20Da camera at ISO 800 for 5 minutes. Stack of 4 exposures. Shot in Queensland, Australia, July 2006.
The bright galaxy NGC 7331 in Pegasus, accompanied by several small, faint companion galaxies to the left of 7331, while southwest (lower right) of 7331 is the group of galaxies called Stephan’s Quintet, though only 3 are immediately obvious here. This is the group, numbered NGC 7317-18-19-20, with one anomalous member with a different redshift than the others, but which is not physically associated with the group. This is a stack of 5 x 8 minute exposures with the Quattro 20cm astrographic Newtonian reflector at f/4 with its coma corrector, and with the Canon 5D MkII at ISO 800.
