Hi,

Although I can't spin the mirrors till the epoxy cures completely 
(well, I "could"...  :o)), here is the field of view at 8 feet:

The black area (black felt back ground) is through the mirror and the 
outside is a combination of the room and such.  I probably need to 
back off a bit more.  I will also paint the camera surfaces flat 
black at the first opportunity.  I am expecting "ghosts" till 
then.  But the field of view is great!!  I need to make the spark 
target vertical too instead of at an angle.  See those hot 
pixels...  This camera is considered "expendable" :o))  But it is in 
no danger at all.

Here is a four second exposure in a pretty dark room:

It has manual noise reduction (just dark frame subtraction) but it 
looks fine as far as noise level goes.  I can fiddle with the SISG to 
fire at very slow rates.  The camera holds 84 pictures at this level 
and the remote control works fine.  So I should be able to just blast 
pictures like crazy ;-))

The camera can scan at over 50,000 feet per second >:-)))  But 
probably it does not need to be nearly that fast.

Charging the batteries and curing epoxy now ;-)))

Cheers,
