RE: [APML] Please help with red splotch problem

["Jason Carden" <jcarden@austin.rr.com>]

Soon as Greg asked about a light on the camera it hit me.  I know
better, I just totally forgot it was there. I've normally been using a
Minolta SR1s which is completely manual and no meter.

Funny thing is, the first time I saw this I was attempting to photo M8.
I thought it was part of the nebula. :)

Thanks folks!  I've got a trip to Big Bend National Park in August and I
want to get all the kinks worked out so I can bring home some descent
images.
