Although I did not have time for real observing last night, took a few minutes for a star test of the Telrad through the trees in my backyard. The modification does work very nicely, and with the pulser on it is very easy to position a faint star to any point in the bullseye - even right on one of the red circles. With the pulser off, it is a normal Telrad, and the faint stars get lost any time they are close to a red circle. To anyone who gets one, the installation is easy, but be aware that with it installed you switch from using 2 AA batteries to using one 9 volt battery. This is implicit in the installation instructions, but it is easy to miss if you think it is a trivial and obvious modification. Having been in electronics too long, I did not read carefully and simply assumed that the same battery would be used. The result was that normal Telrad operation was not restored when the switch was flipped. After a lot of poking around and meter checking to find out what was wrong I finally admitted defeat. Then read the instructions more carefully - bingo! The light went on! Wired in the correct battery and everything worked as it should. It's actually easier to install it right - just don't cut off the supplied 9 volt battery connector and solder the leads to the old battery pack as I did. The moral of the story - no matter how trivial or obvious a job appears to be, be careful not to make wrong assumptions. Good luck with getting and installing the pulser units.
