Al,
Very interesting results! IMO the stacked version is slighty better! ( coming from someone who hsn't seen the sky for the last few months!!!)
Re spectroscope objects...
I'm attaching a copy of the "draft" version of - "Best Celestial objects for Small Spectroscopes" - you'll see that REGOR, WR 11, had already made it to the list as it's one of the brightest ( if not THE brightest WR star visible)
The WC8 classification means high carbon emmissions
CIII/ CIV @ 4650
HeII @4686
CIV @ 4441
some HeII @4861
can't find a definate reference but I think the emissions in the 5600 area are C2 ( there's a band a 5635) [Edit: found a spectrum by Maurice Gavin for WR 120 ( WC7 +O) so very similar to W 11- there's CIII @ 5660 and CIV @ 5780 - interestingly he found the 5660 peak is only about 25% of the 5780 peak??? Does this mean anything?????]
Anyway, a very good catch!! Well done.
