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.

Durst 301 Focusing

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.

I can't seem to figure this out..

..below are images of the baseboard of my Durst 301, first with the negative projected as-is, then with the focusing aid swung in the light path, and with the negative carrier pulled out half way.

Turning the focus knob does not affect the red and green bands / blobs at all (focusing the negative does work, as it should, though).

Is it broken, or am I doing something wrong?

For what it's worth it's a 301 with the condensor and colour head (all filters turned to zero though)

Maybe it can help you (301 and 300 are nearly the same)
