- 1.25" Antares 27 mm Kellner eyepiece with focusable crosshairs
- Ideal for improving alignment of go-to mounts or for tracking during imaging
- Markings on barrel enable consistent focusing for each observing session
Tired of struggling to perfectly center alignment stars? Crosshairs out of focus without your glasses? Here's the solution!
This is a high-quality Antares 1.25 27mm Kellner eyepiece with focusable crosshairs (single), perfect for alignment and tracking. To obtain razor-sharp focusing of the crosshairs, merely turn the upper part of the eyepiece. Focus markings on the eyepiece barrel facilitate consistent focusing from session to session, no matter what the sky conditions. This reticle focusing feature - rarely available in competing crosshair eyepieces - is a great boon if your eyesight is not 20/20 and if you wear glasses.
Whether you want better Go-To, or more precise tracking, a crosshair eyepiece is a must. You can combine this eyepiece with a barlow lens for even higher power and more accurate alignment.
Please note that this eyepiece is not threaded to accept illuminators, so you cannot convert this into an illuminated reticle eyepiece.
