[APML] re: E200 images all very red

["Mark Park" <mark_park@hotmail.com>]

I have the film developed at a local shop, the red is uniform across the 
frame.  The tint does not show up on the piggyback exposures (50mm lens, 
Approx 45 mins).  But does show up on the prime focus exposures.  It can't 
be from an LED because I use a CCD to auto guide.  I try not to let any 
light hit the scope or camera when shooting, though it is possiable that my 
red flash light did shine on it a couple of times.  It seems odd that the 
prime focus exposures all have it and the piggy back ones don't.  I wonder 
if the T-addapter was not on snuggly.

The red tint does not look like the light leak example. It is uniform across 
the frame.  I would expect the processing, except for the prime  focus 
exposures.

Here are three of the full frame images, size reduced, unprocessed, low 
res...

blue any more :~)

Thanks
