Wavelength Calibration

 

Following is my first attempt to capture spectra from the full "OBAFGKM" stellar classification sequence.  These spectra were obtained with an SBIG SGS attached to a Meade 12" LX200GPS on 10/16/06 & 10/17/06.

You can remember the sequence by the mnemonic "Oh Be A Fine Girl, Kiss Me".

There are additional stellar types in the Extended Sequence (WLTYCSPQ).
