Canon 100mm on APS

Near Sur, Oman

The two well-known, but hardly-ever-visible heads in Orion; the Witchhead and the Horsehead. I oriented the image so that you may easily recognise the Witchhead. The Horsehead is a rather tiny indentation in the red nebula in the lower right corner. The bright star illuminating the Witch is Rigel. I have not yet come across anyone who claims to have actually observed the Witchhead visually through a scope. It is indeed very faint. I had great difficulties coaxing it out of the background skyfog, despite the image having been taken at a dark site. Had all kinds of niggling nuisances and cantankerous behaviour from the equipment. Despite having had a target of 3+ hours integration time, all I managed was a bit under two hours. Quite insufficient.
