Well what do you know, as soon as I make myself a wavelength slider for Google Sky, Google go ahead and pass me by by releasing the much anticipated web version of Google Sky complete with wavelength sliders. I still like my little mashup but I look forward to playing with (and taking apart) their new application as well.
Check it out: http://www.google.com/sky/

The web version may be better from an API point of view and have wavelength fading but I think your sky maps are better as you have more coverage and they aren’t as badly distorted near the poles.
