Ortho No. 28-OR 28mm Eyepiece (Pre-owned)

This eyepiece is in great condition. It is highly regarded among astronomy enthusiasts for several compelling reasons. Its design prioritizes optical quality, delivering exceptionally sharp views of celestial objects such as planets, star clusters, and nebulae. This sharpness is crucial for discerning fine details on the surfaces of planets like Jupiter or Saturn, or within intricate star clusters. Secondly, the eyepiece offers excellent contrast, which enhances the visibility of faint objects against a dark background sky, making it easier to spot elusive celestial phenomena. Additionally, its 28mm focal length provides a comfortable viewing experience by offering a wider field of view compared to shorter focal lengths, allowing observers to take in more of the night sky at once. Furthermore, the Ortho No. 28 is valued for its minimal distortion, ensuring that the images remain true to form without noticeable aberrations. These combined qualities make the Ortho No. 28 eyepiece a favorite among astronomers seeking precision optics that enhance their observing sessions with clarity and detail. There are many reasons to choose this eyepiece, including: 

Optical Quality: The Ortho No. 28 is known for its exceptional optical performance. It delivers sharp and clear views of celestial objects with minimal distortion. This is crucial for observing planets, star clusters, and nebulae, allowing you to see fine details and subtle features that might be missed with lower-quality eyepieces.

High Contrast Views: It offers excellent contrast, which enhances the visibility of faint objects against the background of the night sky. This feature is particularly beneficial for deep-sky observing, where contrast can make a significant difference in spotting elusive nebulae and galaxies.

Comfortable Viewing Experience: With its 28mm focal length, the Ortho No. 28 provides a relatively wide field of view. This wider field makes it easier to locate objects and observe larger portions of the sky without needing to constantly adjust your telescope's positioning.
