Rob,
Good start.
Was that an Atik colour CCD?
The "dip" at the end of the green looks like it could be associated with the RGB filters....
Have you done any processing on it yet? Rspec or Vspec.
Merlin,
It's a colour ccd, one of the older Toucam chip models. The IR filter was in place. Also had a problem with dew. I don't usually do star spectra, strictly dedicated to minerals, but I can see why astronomers get hooked on it
The UV-IR only limits the extent of the spectrum to roughly 400nm - 700nm.
A picture of the stars may show you what they look like - but a spectroscope shows the soul....
Hmmm
yes the sky glow filter would skew the balance.
You should remove all the filters for spectroscopy....
Yes -my thoughts on spectroscopy...I don't know how original it is....may have heard it somewhere...but it does reflect how effective spectroscopy is in analysing the "fingerprints" of the stars...a bit like looking at their DNA.....
