Telescope Accessories

• Fits telescopes with 1.25” focusers or visual backs, 90° viewing angle, best for observing objects overhead
• Accepts standard 1.25” eyepieces, Barlow lenses, and other accessories with a 1.25” insert barrel

The Sirius Optics 15mm 68° WALER eyepiece delivers a wide-angle field of view with generous long eye relief, making it ideal for comfortable extended viewing sessions—especially for eyeglass wearers. Enjoy sharp, immersive views without the eye placement sensitivity common in shorter focal length designs.

Getting your back-focus distance right is essential for sharp, well-corrected astrophotography and sometimes you need more than thin shims to bridge the gap. This M48 x 0.75mm aluminium alloy spacer ring provides 30mm of solid, threaded spacing to help you build out your imaging train with precision. Also available in various sizes to suit your specific setup requirements.
