All Ex, if you got your problem with a stripped BD Plan you definitely have to close the light path between the inner and outer shell because definitely a LOT of light would enter there.
If the problem also occurs with a non-stripped objective I can't help.

As I have mentioned above, I have made an automated rear focussing mechanism. For that I have modified a cheap M42 bellows in a way that it can be mounted on acra swiss clamps: http://www.photomacrography.net/forum/userpix/1572_P1590770_1.jpg The front part mounted in a fixed Position, the rear part...

Adapter plate on stack shot. This is important: I have drilled 2 additional holes for better fixation (the 2 original holes are a joke). The plate allows me to mount acra swiss quick release clamps or the 45 mm pipe clamps for the M42 tubes. http://www.photomacrography.net/forum/userpix/1572_P159073...

Hello Charles, thats a nice solution with the Bridgelux parts, if I had seen that earlier, I would probably have gone that way. However, in between I have done some testing and found a nice (seems so) solution with a collimating lens placed directly in front of the LED. This lens is kept in place by...

@ChrisR: Actuallly I also have a BD Plan Apo (40x 0.80), I came across it before I got the BD Plan 40x ELWD and could not resist. I am very sure that the thread to remove the outer case is in the same position as for all the other BD Plans - just beside the knurling. But removing that outer case doe...
