Hi All,
Been getting back into this lately, since the thread in the Astronomy Science section (plenty of help there).

IC2448 is a small PN near Beta Carina.
12" f5 with Star Analyser
1x10min data -darks & bias
Data reduction with VSpec.
Two line callibration with 0A and Ha(6562.72A)
OIII line measured.
Colour spec synthesised from data.
Hope this makes sense.
:D

Wow...what a nice spec'!!!!!. Great work there, Jeff:D:D

There's some strong telluric signature there (O2 and H2O absorption), then the 2 strong emission peaks near 9000 and 10000A and the double peak that looks up around the 11000-11500A mark...interesting. That smallish peak in/near the UV end is most likely Hdelta/epsilon. There's heaps of absorption lines in that spec'...many probably metals and such, plus tellurics.
