Quote:Luck?,,perhaps, but possible the inconsistencies have been overstated a bit.
Quote:RKEs aren't cheap anymore I notice and they used to be bargain basement cheap - $40 or some such. I recall Mounsey liked them a lot - said they had a color white tone compared to TVs and the warmer coffee tones. He was impressed with them greatly on the moon but less on Jupiter.
Too bad QC is random as I was thinking of getting a new pair of 28s got my binos too.
Quote:AFAIK, the RKE's are merely "coated," not FMC like the TV Plossls or even FC like Brandons. Simple coatings can give a darker background and increase perceived contrast for planet features and bright nebulae and galaxies. They might also display deeper colors for bright stars.Mike
Quote:Though multi-coatings can, indeed, produce a different spectrum of transmission than simple magnesium fluoride coatings, the different spectrum is usually a HIGHER brightness/transmission at all visible wavelengths.
Quote:2) Ditto comment number 1 on planetary viewing. Reducing light scatter is the way to go to improve contrast on small details, not the other way around.
Quote:3) Light transmission and concentration of that light (see the spot diagrams for the design) are what is going to improve the brightness and contrast on DSOs, along with good polish on the lenses, strict adherence to the design parameters, and the long laundry list of other factors that improve what we call "contrast".
Quote: 4) Seeing colors in stars is a matter of improving transmission through the eyepiece. Flattening the curve of the spectrum of transmission may or may not improve the visibility of colors in stars. Accenting the colors at the spectral position of peak sensitivity of the color-seeing cones in the eye might, though. Ironically, a non-flat spectrum might enhance colors more than a flat spectrum.
Quote:I think the same thing occurs with eyepieces. People read a lot of praise for a specific brand or model, they buy one of them, and they discover for themselves that "the reviews were right". It's a case of "it's new, and different than what I had before, so it's obviously better", whether that's true or not. Six months later, the honeymoon is over, the product is just what it is and it may not be better, so it goes on sale or gets replaced with something different and, different is better.
Now obviously this isn't always true. Some people actually evaluate the eyepiece without any judgment-clouding preconceptions. But I'm not sure it is the majority of comments or reviews.
