Rigel Systems Aline Telescope Collimation Eyepieces: Precision Alignment for Newtonians & Dobsonians

Key Features:

Superior Brightness: Offers brighter visibility compared to traditional Cheshire eyepieces, delivering enhanced performance at a fraction of the cost.
Essential for Rich Field and Fast Telescopes: An indispensable tool for aligning rich field, fast Newtonian, and Dobsonian telescopes, ensuring optimal performance.
Easy Centering Visuals: View through the Aline to see a bright white circle around the image of your eye's pupil, simplifying the process of centering primary and secondary mirrors.
Proven and Popular Worldwide: Thousands of Aline collimation eyepieces are in use globally since their introduction by Rigel Systems in 1995, attesting to their effectiveness and popularity.
Innovative Retroreflector Design: Utilizes an ultra-reflective microprism retroreflector, harnessing the light gathered by your telescope for a brighter image than classical or other reflective Cheshire designs.
Enhanced 2" Aline Model: Features a 3/4" black center in the microprism reflector, complementing the 3/4" fat triangle mirror center spot for streamlined and improved collimation.
Available in 1.25" and 2" Sizes: Suitable for a variety of telescope models, providing flexibility and convenience for astronomers.
Simplified Collimation: The design enhancements in the 2" Aline model, including the beefed-up sides of the mirror center spot, make collimation easier and more accurate.
