Ross,
That's interesting. From your plot of M42 with equal brightness for OIII/H-beta and H-alpha then a UHC filter (which passes both at the same time) looks ideal for general imaging of this object!

Hello Ross,
I was very intersted in your latest stellar spectrographic images and was just wondering if you knew whether there were many other stars which have a similar spectro reading as our sun.
Would it be possible for you to show a spectro analysis of our sun as a comparison, please?
Regards.

Yes Paul, my earlier experiments using a diffraction grating to examine the daylight (i.e. solar) spectrum are covered in this topic:
