Chris,

the Witch Head Nebula is just outside the frame. I did photograph this
region, too, but transparency was not too good on that particular night,
and the nebula is barely visible on the image. Also, unhypered PJ-400
seems to lacks the blue sensitivity necessary to get a good shot of the
Witch Head. Well, better luck next time. After all, this was only my first
attempt to shoot the "Wicked Witch" <g>.
