The bars at the bottom are done by cropping a section along the spectrum, reducing it to one or two pixels height, then expanding it to 20 or 30 pixels height.

Keep up the good work & keep posting your results!

Hi Rob.
I have ordered my Star Analyser and am looking forward to getting it .
Can you please explain how you obtained the larger and taller spectrum images at the bottom?Is this done in software? I'm a bit confused.
