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.
M27 with 130mm Astro-Physics apo at f/6 with no field flattener (slight camera tilt results in more coma at left of frame), for stack of 6 c 8 minute exposures at ISO 800 with Canon 7D (stock camera, not modified). Auto-guided with SG4. Worked perfectly.
9-day-old gibbous Moon, taken April 23, 2010, with Astro-Physics 130mm apo refractor, plus 2x Barlow for f/12 and 1600mm focal length. Canon 7D camera at ISO 100. Seeing poor -- this was the sharpest of the lot.
