IC 289, a small faint planetary nebula in Cassiopeia, here showing as a small purple disk at centre, just a little larger than the stellar disks. It is 13th magnitude and is 40 x 30 arc seconds in size, so not quite star-like but not at all obvious visually. The tip of the Soul Nebula is at lower right. IC 289 is considered the most difficult object to observe on my list of 110 Finest NGC Objects in the RASC Observer’s Handbook. It is the only IC object on the list. This is a stack of 5 x 8 minute exposures with the Quattro 20cm astrographic Newtonian reflector with its coma corrector at f/4 and the Canon 5D MkII at ISO 800.
Nebulosity in Auriga, including IC 405 Flaming Star Nebula (right), IC 410 (centre) and IC 417 (left). Taken Oct 15, 2007 with 77mm Borg refractor at f/4.3 and with Canon 20Da camera at ISO 400 for stack of 4 x 10 minute exposures. Used Skywatcher HEQ5 mount and ST402 guider.
IC 405 nebula in Auriga taken with 5-inch f/6 apo refractor with field flattener, with Hutech-modified Canon 5D camera at ISO400, for stack of 5 x 14 minute exposures. Taken from home on December 17, 2006.
