Did you know that the Promaster extension cable
for the Pentax costs $60? They are probably made
in China for a tenth of this. I'll use a hotshoe
adapter in the meantime. And perhaps make a proper
cable later by connecting two of them together.

If you need to move the flash a distance from the camera, use an
extension cable (Promaster has a nice one that preserves the Pentax
dedicated connections ... see
<http://www.promaster.com/products/productpage.asp?sm=sm2_flashbrackets&product=8144>
or

note that the item pictured is for a Canon ... the product code for the
Pentax unit is 8179 but there's no picture)
along with the Wein Safe Sync for a non-dedicated flash unit.

On the microscope, which has a simple flash device with no
synchronization, or TTL, or anything at all automatic ... the flash
will flash once and then not again. Its not a question of charge the
flash is made to strobe and will go on flashing with a film camera
until the cows come home at 1/2 second intervals.
What am I doing wrong? I haven't spent much time learning -- I've been
using the camera and it works fine with ordinary lighting on the
scopes. In green, M, or any other setting I might like to use. All I
want is for the flash to flash each time the shutter is opened. The
exposure is controlled by other means and the camera is not expected
to think about this.
