Brightest stars in Leo!

[Gasman]

Hi

Had the somewhat mad idea to plot the brightest stars in Leo last night, very clear and still. Balmer lines abound in that constellation .

I may have over crowded the graph somewhat but WTH!

and I`m 99% certain this is R Leo the FOV is not terribly clear in the LODESTAR! anyone familiar with its spectrum care to put me right please?.

cheers

Well I tried to edit this post to explain the bottom right spectra but SGL edit seems to have thrown a wobbler!. They are in fact the individual spectra for the 8 stars!

Hi Steve,

I can see you have been very busy and got the hang of the Alpy.

I would check the Gamma Leo calibration. The 'Ha' line might be telluric O2 at 686.9nm?

According to Wiki R Leonis is a cool M8IIIe type. This seems consistent with the molecular bands that are clearly evident.

cheers

Thanks John I thought that gamma Leo looked a bit iffy !
