The GSO 3x ED Barlow Lens is a high-quality optical accessory designed for telescopes with a 1.25-inch diameter. This fully multi-coated lens provides clear and sharp images by minimizing glare and ensuring maximum light transmission. This Barlow lens is perfect for enhancing the performance of your telescope, allowing you to view celestial objects with greater clarity and detail. Its 3x magnification also allows for a closer inspection of the night sky, making it a valuable addition to any astronomer's equipment. I bought it to match the pixel size and sampling for planet imaging, not used very often however.
