Hi Ken,
I've had no success lately on any of the projects with varying spectro designs - been totally slammed with work so far this year...
Managed to get the SA100 located in front of a 135mm + 2x teleconverter capturing spectra with the 350D. Just working out the various lines/bands and instrument response thru VSpec at the moment. Appears to be approx 3 - 4 angs/pixel
Did all the major stars in Crux a couple of weeks back, which I plan to compile into a single image...Certainly looks different
cheers
Mark
