The single biggest reason to buy is the combination of \u003cstrong\u003eEMD coatings\u003c\/strong\u003e and argon purging, which together preserve contrast and keep internal optics free of moisture and fogging during use in damp conditions.

It is also appropriate for those building a modest eyepiece set who want a mid-power option around 15mm to use for planets, the Moon, and bright deep-sky objects.\u003c\/p\u003e\n\u003cp\u003eIt is less suited to observers who require very wide apparent fields or the absolute highest-end ocular glass; those users should look at specialty wide-field or premium series.
