Observations corner

This section is dedicated to profile examples with spc file download.

Some spectra have been otbained by several spectroscopy amateurs with different instrumentation. Only the Resolution is indicated. Refer to author's web pages for their instrumental configuration.

The profile file contains the raw data, no correction of flux have been applied. This set represents the variety of response curve which alter the continuum of each object.

A big thanks to the contributors !

Sorry, this is still Work In Progress !


A classical reference - the best object to start with - several spectra at different resolution

SS Cyg

A cataclysmic variable - not easy to catch but quite surprising

Be Stars Atlas B-stars which exhibits emission lines with variation over time - see the Atlas list.
O Type stars O stars
B Type stars B stars

F Type stars F stars
G Type stars G stars
K Type stars K stars
M Type stars M stars
Peculiar stars Special stars
Planets Planets
Comets Some comets...
Planetary Nebulae Planetary Nebulae are very fun to observe, and some computation on electronic density can be performed...
Nova Nova are very interesting to record and to follow over time
Galaxies Seyfert galaxy
Quasars Still to capture...
