Description
Be captivated by the celestial wonders with the 4.7mm Ethos-SX 1.25" with 2" Eyepiece Adapter, a high-quality, durable, and versatile piece of optical equipment from the renowned brand, Tele Vue. This innovative eyepiece adapter is the result of the relentless pursuit of perfection by Al Nagler and Ethos designer Paul Dellechiaie, who aimed to replicate the 110-degree field size of the LEM Simulator optics, originally designed for training NASA astronauts for lunar landings.The 4.7mm Ethos-SX, much like its predecessor, the 3.7mm model, is meticulously designed and crafted to offer an exceedingly wide field of view. It combines all the necessary elements - contrast, color rendition, distortion correction, and center-to-edge sharpness - to deliver a natural, immersive viewing experience. When compared to a lower power eyepiece with an equivalent TFOV (similar field stop), such as an 11mm Plssl (9.1mm field stop), the 4.7mm Ethos-SX provides greater power for higher resolution and a smaller exit pupil for a darker background. This enhances contrast and reveals a deep sky experience that exceeds your expectations.The 4.7mm Ethos-SX is a 1.25" format and is parfocal with the wide range of 1.25" Tele Vue eyepieces, making it a reliable and versatile addition to your astronomy equipment. To ensure compatibility with various telescope models, a 2" adapter is included. Whether you're an amateur astronomer or a seasoned stargazer, the 4.7mm Ethos- SX 1
