illuminated F/stop dial on my 50mm APO Rodagon N.

Exactly. It's basically a useless feature. It only "works" when you're
making the exposure. What's the point?

Focus, stop down, then turn off the enlarger?

FWIW, I like the feature.

I don't have any problems seeing the digits on my Schneiders or my Nikkor.
As stated previously, I don't change the apertures much anyway but I can
always take a look at them in the dark and tell what the setting is.

I have a small AA flash that I do the same thing with, though I'm now
lusting after a red LED penlight. The little Mag-Lites have a filter kit,
not sure how "safe" the red filter in this kit is but for short periods it
should do. The flashlight has one other advantage, an illuminated aperture
ring is no help at all when you drop your pencil on the floor!

The illuminated dial on my Rodagon is not illuminating the F/stops

On my 150mm Rodagon there is a plastic piece on the periphery of the
rear element mount that needs to be illuminated. When the lens is
in an adapter for use in a turret then light no longer gets to this
piece and the aperture ring is dark.

Take off the lens board and look from the rear: do you see the
plastic thingy? You may be able to drill a hole or do some filing
to let light in - with a thread adapter that option is out, though.

#1) Get some rubylith and re-lens a penlight. #2) Pay someone
to do #1 for you: Google for "penlight red" or "penlight safelight",
"red flashlight" etc..

I have the penlight tied to a string tied to the enlarger bench.

The illuminated dial on my Rodagon is not illuminating the F/stops when
used on either my durst M605 B&W, or my LPL 670 when I'm doing 35mm. Is
there an adjustment or slide I'm not seeing? It never bothered me until
I was at the B&H website and was looking at this lenses spec's. Am I
missing something other than the illuminating F/stop's?

Regards.

It depends on the density of your negative. Less dense negatives pass more
light to the window. That's been my experience with my 80mm Rodagon on my
Bessler 23c, anyway.
