Hi Tom,
How did you arrive at this conclusion? What's the math behind it?
Might be worthwhile to know.

Thanks, Tom. Ed also suggested something similar. Since it's a cheap
and readily available solution, I'll try that first. The technique
should at least indicate if there's a need to go further. Of course, if
there's a problem with the lens, which may give an unsharp image on one

Hi Shel,
I can't answer your question, but I have a question of my own: Will the
23CII do 4x5? I assume it will do 6x7. I've seen a couple on ebay, but the
sellers don't specify.

Thanks Tom. I think my next enlarger should be capable of 4x5, since I
occasionally shoot with my old Speed Graphic, and I want a cold light

I think Bill meant 6x9. The 23C series are 2-1/4 x 3-1/4 enlargers.

Technically, that is the largest format the 23C can do. However,
the diffuser is big enough to print the 6x9 negative either

Hi Shel,
The answer is yes. The goal is to adjust the condenser such that the
point on the light is the centre of the lens. I use the 50, 80 and 105
lenses with mine and they correspond to the 3 format settings.

I just picked up a fine Beseler 23CII condenser enlarger to
complement the dichro head model that I have. There's an
adjustment on it that allows the condenser to be moved up and
down relative to the negative, and it's marked for different
formats - 8/16/35mms
Thanks for the good tips, Ed. Since I've a dichro head on the other
enlarger, this one will stay as a condenser unit.
The heat absorbing glass didn't seem to be needed with the Omega
D2V-series, but it might be helpful if I were working with 2¼, and, of
course, the Beseler is designed a little
