How do I fine focus with Durst M301 green & red colour bands mechanism ?

I think you put them in the light path, and then look for the green & red images to co-incide. I've got a manual for the M301 somehwere & can check, but am pretty sure that's how it is done.

Try & and if it doesn't work, I'll dig out the manual.

Thanks,Charlie. As suggested by you, the filter has to be kept in the light path and the negative stage has to be pulled out half way. When the neg.is properly focussed, the red and green bands dissappear. Regards, Hansraj.
