Oberwerk Deluxe Series are close to The Ultra Series in optical performance and construction quality, but at a substantially-lower price. The 10×50 Deluxe has excellent sharpness across almost the the entire field, with rugged construction and precise center focuser. Of course these are fully broadband multi-coated, waterproof, and nitrogen charged. Eyepieces are threaded for 1.25″ filters. Includes a rugged soft case (same case as the 10×50 Ultra) and our premium heavy-duty denim strap.
