I guess everyone's colour perception is slightly different- esp. at these subtle levels. The eyepieces I like best depend on the object I am viewing. M42 looks fantastic through the 28mm UWAN(0.8 of a degree and 80X), larger galaxies like M83 are fabulous through the 13mm Nagler (180X) and the planetary nebulae are best at higher power in the 9mm Nagler (260X).
I do really like the immersive nature of the UWAN though.
I also think I need a planetary eyepiece or two around the 300-400X range since I have tracking and the parracor is not compatible with most barlows. Clayton bay is a place were really good seeing is common, being surrounded by water and having no hills around.
