The 92° Series 17mm LER combines a 92° ultra-wide field of view with comfortable Long Eye Relief at a lower magnification ideal for framing large deep-sky targets. At 17mm through a 2" barrel, you get wide, bright views that reveal the full extent of nebulae, open clusters, and rich star fields. Previously priced near $800, the current $299 price makes this level of ultra-wide-field performance genuinely accessible.
Key Features
- 92° apparent field of view — among the widest available, delivering an immersive panoramic view that reveals deep-sky objects in their full spatial context
- Long Eye Relief (LER) design — generous working distance for comfortable extended viewing, fully compatible with eyeglasses without field loss
- Premium multi-element optics with lanthanum glass for sharp, color-corrected images across the enormous field
- 2" barrel for maximum light throughput and true wide-field performance
- Argon-purged waterproof housing — sealed and fog-proof for dependable all-weather performance
- Enhanced Multi-Layer Deposition (EMD) coatings on all air-to-glass surfaces with edge-blackened elements
Ideal For
- Wide-field deep-sky observers who want large nebulae, open clusters, and galaxy groups framed within an immersive 92° field at comfortable magnification
- Eyeglass wearers who need generous eye relief without sacrificing any of the ultra-wide field — a genuine advantage of the LER design
- Dobsonian and large-aperture telescope owners where a 17mm provides a beautifully wide, bright view at moderate magnification
- Observers who previously couldn't justify ultra-wide-field pricing — at $299, this delivers 92° immersion that was formerly an $800 investment
