About This **62° Wide, Aspheric Views** Aspheric optics and full multi-coatings reduce aberrations and stray light for sharper edges and higher contrast—ideal for star-hopping, clusters, nebulae, and lunar detail. **3 Go-To Focal Lengths (23/10/4mm)** 23mm for wide-field sweeps, 10mm for clusters and lunar features, 4mm for high-power planetary views. Standard 1.25" barrels fit most reflector, refractor, and catadioptric scopes. **Includes a 5X Barlow Lens** Boost magnification on demand by pairing the Barlow with any eyepiece to reveal finer planetary and lunar detail. *Note: Very high power is seeing-dependent—precise collimation and focus recommended.* **4 Essential 1.25" Filters (2× Polarizing, 2× Moon)** Polarizers help tame glare and increase contrast; use the pair together to fine-tune brightness. Moon filters reduce eye-fatigue during bright lunar phases. All use M28.5×0.6 threads. **Comfortable, Durable, QC’d** Soft fold-down eyecups, knurled anodized housings, blackened lens edges, and internal glare control. Each piece is optically inspected and ships with protective end caps and a padded carry case/pouch.
