I just thought I'd have another go at it. When I did the lines seemed much better defined.

No, no preprocessing except for dark and bias. I'm flat-out getting my head around just displaying the graph with scale.

I agree with the distance to CCD/scale problem 'though. I have my grating practically at the front of the ST in a filter wheel. I will have to move the mirror forward to allow for further seperation due to focus issues.

I do appreciate the help everyone has supplied so far, its been great. At the moment I sit here in 30+ temps trying to better my data.
