Region of nebulosity around the open cluster M52, at top left, including the Bubble Nebula, NGC 7635. Bright nebula ar right is NGC 7538. Small star cluster at lower right is NGC 7510. Region of nebulositry at top is Sharpless 2-161 and twin forked nebulosity at bottom is Sharpless 2-157. Stack of 5 x 15 minute exposures (last taken at moonrise) with the Canon 5DMkII and A&M/Officina Stellare 105mm apo refractor with Borg .85x reducer/flattener for f/5.2. Autoguided with NextGuide and 66mm Willliam Optics apo for a guidescope. All on Astro-Physics Mach 1 mount. A windy night but clear.
Comet Hartley 2 near the Pacman Nebula, NGC 281, in Cassiopeia. Stack of 4 x 6 minute exposures at ISO 1600 with Canon 5D MkII on A&M 105mm apo refractor at f/4.8 with Borg reducer/flattener. Bright star is Alpha Cas, Schedar. Autoguided with Celestron NexGuide autoguider. However, image of comet core is from only one exposure to minimize trailing from this fast-moving comet.
Bright rainbow created by Sun low in west just about to set with raindrops in the air to the east, and light rain falling at the time. Taken with Canon 7D and 10-22mm lens at 10mm, in two sections, stitched together in Photoshop. Note: bright interior region inside inner bow, darker exterior region, supernumerary arcs along inside edge of inner bow at top, reversal of colours in two bows, and bright red portion of the spectrum from very red sunlight from low sun angle. Taken from southern Alberta, Canada.
