New Spectral Atlas -Richard Walker
« on: 12:02:37, 11 November, 2010 »
Richard Walkers Page

The link to Richard's Spectral atlas is near the bottom of the page.
It's available in English.
This is a great resource for anyone interested in stellar spectral classification. He give sample spectra for all the different classes of stars (OBAFGKM) and provides annotated absorption/ emission line positions as well as a brief but complete overview of each type.
Strongly recommended to all amateurs, whether you have a spectroscope or not.

Excellent Ken.I wish I could fit building a spectroscope in with all the other stuff I'm trying to do.. :sleepy: John
Woe unto him ..or her..who tries to guide the LX90. Let him..or her..rejoice in a lightweight scope upon the mighty EQ6. Mind you,I'd sooner be looking through my 6"f8 while the clouds look down the 8"f4 Le marchant configuration. And there should be a constellation called 'Camelot' and I would worship it in the anticipation of a big lottery win. Maybe I'll move to the Isle of Man..damn these drug
