Omegon Cross thread eyepieces Pl\u00f6ssl 9mm -<\/strong> Illuminated and adjustable reticle for precision<\/strong>
The Omegon Crosshair eyepiece Pl\u00f6ssl 9mm helps you track stars precisely during astrophotography. The double reticle is illuminated and extremely fine, so you can easily center a tracking star. You don't have to cover the star like with a single reticle, and you can immediately see small deviations. The reticle is infinitely adjustable, so you can always align perfectly. This makes it ideal for off-axis guiders and precise tracking.<\/p>\n\n\n\n

Clear and sharp image<\/strong>
The four-lens Pl\u00f6ssl design delivers a bright image with high contrast. The multicoating ensures that the image remains bright and sharp, even with dimly lit tracking stars. You can also adjust the reticle to suit your eyes, keeping it sharp and comfortable.<\/p>\n\n\n\n

Versatile use<\/strong>
This eyepiece is not only useful for astrophotography. Use it also to measure image fields, center the Pole Star or determine the angle of double stars. It is a practical tool for anyone who wants precision when tracking or positioning objects.<\/p>\n\n\n\n

What we recommend<\/strong>
\u2713 Astrophotography: ideal for off-axis guiders and tracking viewers.
\u2713 Double stars: easy angle determination and sharp tracking.
\u2713 Monturing alignment: precise positioning with the North Star.
\u2717 Deep-sky observation: not intended for visual observation of nebulae or galaxies.
\u2717 Planetary or lunar observation: limited use.<\/p>\n\n\n\n
