Richard,
A couple of comments..
Can you add a flip mirror in front of the camera? Makes it much easier to aquire the target.
( I can use GOTO and CdC with the NEQ6pro to just "drop" the target onto the grating....)
It's standard to present the spectra with the zero order to the left - this gives a spetrum orientated with blue to the left and red to the right - usually needed when you start to do calibrations...
Good start.
Well done.
