Re: High speed Tesla spark photographs

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,
