Information based on my experience and manufacturer claims, may not be 100% accurate
Lamps are used
Spectra taken with
The SBIG SGS on a 12”
LX-200GPS from my
Tucson backyard on
October 16 & 17, 2006.
The OIII emission lines were thought to be a new element in the early 20th century, “Nebulium”.
Amateur spectroscopists were asked to obtain data on this star, which was a target for the COROT satellite.
A very young star, still undergoing contraction.
This data was obtained early Monday morning at TSP Upper Field.
Blueshifted absorption feature provides a basis for calculating radial velocity of the expanding shell.
Preliminary calculation from this data is
~ 200 km/sec.
