The attached spectrum of ETA shows two large peaks, which are well above anything else.... these are Ha (6563)and Hb (4861), the Ha is red,red,red, and the Hb blue.
Very little if any OIII ( 4959/5007) So based on this spectrum, it would be 4 parts red to one part blue.
What I'm trying to get at is the end result will always be biased based on "perceptions" ( and the responce of the CCD!)
Thanks Ken. The OIII's are right behind the keyhole that patch and the rest is HA's.
