Thanks Pau. It's a 50mm Tominon.

Just back from QMC AGM - followed by curry etc., of course! - Jackie was in fine form along with Nigel, Joan, Dennis and Paul. The top of the GF ocular comes level with the top of the Dialux/Brunel photo tube and the Tominon screws on immediately above - not a lot of clearance: http://www.photomacro...

http://www.photomacrography.net/forum/userpix/16_IMG_1524_2.jpg Cactusdave asked about the configuration of my set-up for photomicrography on this Dialux. This is a semi-experimental afocal setup. It consists of a Leitz phototube with a Brunel (I think) over-tube which has a 42mm thread at the top ...

Thanks Pär - well spotted! - I've been intending to do this for some time and it seems to be working well.

Some while after the original posting, but I just wanted to post my thanks to Steve for these extremely helpful images: I recently purchased a Dialux frame "for spares", hoping to be able to get it working. It turned out that the focus block was jammed in such a position that there was no access to ...

Wow! - really nice image

Some wonderful images - the stereo images certainly show off Biddulphia well

Beautiful, as always!

If you know how to achieve darkground with a wheel or patch stop, then you know how to do COL: just use an undersize stop in the condenser filter holder. You may need to rack the condenser up or down bit from the normally optimum position to achieve satisfactory results.

Thanks Stefan. I had an inkling it might be something of the sort.

The stereo images were generated by Zerene with a 3% shift. I had to edit one image of the pair for halo artefacts
