Many thanks!
I just use the cheap generic RDFs - as sold by Celestron, Orion, etc. I've had 4 or 5 over the years with several different telescopes, and all have had infinitely adjustable brightness.

If you're going to hack an existing RDF, just adding an adjustable resistor in series with the LED should do the trick.
