Quote: "Using the 36" f/5 Yard Scope and a 12mm eyepiece (360X) shows a bulls-eye of nebulosity, with the inner ring as light green and a light pink outer fringe. "
I have found the following picture of NGC1535 (yes, it resembles the Eskimo nebula). I have also made some search and it seems that the nebula is an OIII object. The outer ring should really be green like in the picture.
Thus this is another case (besides the "ears" of M27) where reddish is reported in place of OIII.
In fact the theory that "every time an expert observer sees a color, it has to be real" is contraddicted once again.
No, it is not necessarily contradicted. Images of planetary nebulae can be processed in ways which do not present the same level or shade of color detail which the eye sees. You might want to check out the following narrow-band images of NGC 1535, as the H-alpha one shows that there is definite H-alpha emission:
