My spectrums - Mars, Saturn, Betelgeuse   Message List  
Reply Message #1699 of 2498 |
Hi all

I'm starting with Star Analyser and I've got few spectrums already. I welcome
any comment on my bands identifications.

Latest is mars:

(aligned on 500 and 678 nm oxygen bands)

First shots with Saturn captured H-alfa absorption line (it's a big ball of
hydrogen isn't it? :))

Good beginnings.... Mars should show the reflected sunlight from a G2V star.... Saturn has some methane absorption features....I have a Lowell image which ...

Congratulations on your first spectra! I agree with Ken. The broad band in the Saturn spectrum is probably Methane, not Hydrogen (remember what you see in a...

As Ken and Robin already pointed out, it´s the very prominent Methane absorption band at 620nm. For comparison, raw spectra of Saturns rings and planet. The...

I've put that spectrum through VSPEC and calibrated it on the oxygen lines as with Mars. The result showed that the methan band does exist, and H-alfa is on...

Hi Piotr, The solar spectrum does not show O III so I do not think your line identification is correct. You could try comparing your Mars spectrum with the G2V...

Oh, thanks for the hint. Was looking on bad chart that had O-III noted. What I see is then not O-III but "c" Fraunhofer line at 495 or something close to that....
