For my Chrissy present I "arranged"
that my wife gave me a star analyser as a present.
It is not the easiest thing to master but I'm giving it a go. I have taken spectra of various stars and tried to calibrate them using my ST9E.
The programme recommended id Visual Spec and it is far from user friendly and a bit prone to crashing.
anyway here is my first reasonably successful attempt.
The star is V385 Car. This is a may 7.7 WR star with strong emission lines.
The exposure is only 15 secs.
I'm pleased that I have been able to calibrate the image reasonably well compared with a spectrum I downloaded from CDS.
Now to try to identify other things.
