[APML] Successful Images

["Thomas W. Earle" <twade@bmi.net>]

My slides arrived today, and I was pleasantly surprised.  As noted
in an email earlier this month, I stated several shots may have been
ruined due to loosening the camera mount rather than tightening it.
Fortunately, this was not the case as the stars are pinpoint so no
flexure problems occurred due to my mistake.  However, given this
fact, perhaps I tightened the mount all along and just got confused
in my sleepless state or perhaps the "backup" mounting ring was just
enough to hold it steady.  In all likelihood the former is probably
the more likely scenario.:-) 

This was the first time I ever used E200 and it sure is an awesome
astrofilm.  I have unbelievable detail on the 300mm and FSQ shots of
the M8/M20 region.  What's really amazing is how well the E200 did
on M20 which is primarily blue.  I'm beginning to wonder why this
film has gotten such a bad reputation on its blue insensitivity.
Looking at my slides and seeing the results of Chris Cook's Rho
Ophiuchi Region, I'm beginning to have some doubts.  Granted, I have
access to a really dark site so the slower blue layer has time to
"develop".  This is probably where the problem lies.  For less than
ideal locations, there is less time to expose before the sky begins
to fog the film.  Because of this, the blue layer doesn't get a
chance to "shine"; whereas, in a very dark site, exposing 60-75
minutes at F/4.0 allows the blue layer to develop to its fullness.
Does this sound logical?

I hope to have them available for your viewing by mid August.
