Let me know.

Thanks Ken but problem solved! I was right, it was the grating "unit" but not the grating thank goodness. Last night I got the same extended stars but then noticed that the little rolled-up light card tube I use as a dew protector had a loose corner that curled out on the inside of the tube. I rotated the tube 90-deg and I had good stars again. So a simple bit of glue will fix it, phew!
FWIW, here's the spectrum I got last night.
