ASTRO: Reprocess of M78

I burned in the brightest parts of the nebula in my original post. I've
toned it back some here. Still some burned in areas. 10 minute subs
were just too long. The upper end was just too compressed by the ABG to
get anything out of it. Seems with this camera I need to limit the top
end to about 45,000 ADU if I want to dig much out of the top end. This
went to 57,000.

Third character is a zero rather than a capital "Oh".

Beautiful picture Rick, very smooth.

Rick,

Like it!! Lots of brightness range in this image! You also got a few of
the Herbig-Haro Objects that are in the area at the lower portion of your
image. You just missed McNeil's Nebula (assuming that it's still there).

McNeils would be in the shot if it were there. It is above the HH
regions up toward but not to the double that points to the HH regions
and a bit right. Nothing there but a faint haze that covers the whole
area. Most shots of it didn't go deep enough to show all the clouds in
my shots so it looks to be below them in those shots. Use the double
star as your reference.

I've attached a crop with the area circled. There is a cloud there that
is about the shape and location but it is very faint and the star
totally gone. Can't tell if that cloud is any part of the nebula but it
does have about the right shape.

See http://www.seds.org/Messier/Pics/Jpg/m78mcn1.jpg for a wide angle
shot of the area with the nebula in full display.
