Celestron Starbright XLT Coatings

In July of 2003, Celestron introduced and began shipping a new version of their Starbright coatings on their Schmidt-Cassegrain Telescopes (SCTs): Starbright XLT.  Boasting the highest light transmission for any commercial SCT, Starbright XLT coatings are available as an option on all Celestron SCTs.  The improvement is across the entire spectrum, both visual and photographic.  For complete details, visit:
(this page moves around occasionally on the website so you might need to search a bit)

For visual-only use, standard Starbright coatings are nearly as good as anything on the market, but for a flatter response across the entire spectrum of photographic light, Starbright XLT coatings are worth the relatively low increase in price.
