The sticky was awesome. :D

A few questions. Any instructions on making the variable controller for the Vivitar? How about the mouse/remote release?

I'm looking at purchasing a Canon 350d sometime in the future and already have many of the other items shown in Mr. Krebs's writeup... It'll be a huge leap from the PVC adapter i cobbled together for my anchient Canon FtQL.

Thanks for the help!

Ben...

Glad to hear the info might be useful to you. While I need to do some final editing there are a couple pages on my site that might be of some use. One deals with the control for the Vivitar 283, the other with the technique I use to make the camera parfocal with the eyepieces. (The parfocal procedure is simpler than the one outlined in the "sticky". I needed to change it because my current microscope has a fixed length trinocular tube. It is effective and easier.)

Excellent articles.

A question tho. Why the need for two seperate controls on the flash controller -- the top dial from full to -5.5 in -.5 increments the lower from -2.5 to -8 in -.5 stop increments?

I wanted to cover the range from full power to -8 in half stops. I had 12 position switches so I could not get all positions with one switch. So I used two with a toggle switch to move between them. There is considerable "overlap", but it has actually worked out to be very convenient in use.
