The single biggest reason to buy is its \u003cstrong\u003eextra-low dispersion glass\u003c\/strong\u003e, which noticeably reduces chromatic aberration compared with standard achromats; combined with the fully multi-coated optics the result is a clean, high-contrast image for both planetary observation and wide-field imaging.
