The single biggest reason to buy is the combination of an \u003cstrong\u003e82 degree apparent field of view\u003c\/strong\u003e and well-executed optics that deliver crisp, sharp views across the frame, making planetary and lunar observing more engaging without the tunnel effect common to narrower eyepieces.
