Nice job, Robin. I wonder if a BW TV camera would be able
to pick this up on a 16" telescope...

Hi Eric,

You would still need some sort of strobe technique as the frame rate would
not be fast enough to catch the 30/sec double pulse. I suspect it would not
be sensitive enough either. I have a very sensitive camera and it needs a
few seconds exposure to catch the mag 16 pulsar. To catch it in a 1/60sec
frame I estimate would have needed at least 100x more light ie an 80 inch
scope. I would not mind having a try though if you know where I can borrow
one ;-)

Robin
