Spectrum NGC7009 Questions

[theodog (Jeff)]

Hi All,
My image is of NGC7009 taken with a Star Analyser 100.
30 sec, 12" f5 St7e.

Can anybody identify the bright lines in the spectra?
I assume one is hydrogen and another oxygen.

This should help me calibrate my spectral system?

Thanks in advance.

Hey Jeff,

I've only just been reading about the Star Analyser and Visual Spec... but shouldn't the primary image be on the left? Just based on what I've seen of the examples on the Visual spec web site and tutorial, they all have the primary image on the left...

BTW I have seen an example on the visual spec or star analyser site that shows nebulae spectra, which should exactly answer your question (I think) but I haven't found it yet.

Does anything here help?

Yes Al, when I set the unit up I put the indicator on the left, as viewed from behind the camera. I will have to reverse the image.

Yes. I haven't seen this site before. something in english is good. My problem is that I need some definite spec lines for claibration.
Thanks for your help.

Found it, Jeff.
