When selecting eyepieces for a telescope, consider several factors to enhance your viewing experience. First, identify the purpose, whether it’s for detailed planetary observation, something broader like lunar viewing, or deep-sky observation of galaxies and nebulae. The focal length of the eyepiece determines magnification, calculated by dividing the telescope’s focal length by the eyepiece’s focal […]

The ability of a telescope to “zoom” or magnify a distant object doesn’t directly depend on the cost or the size of the eyepiece. Instead, it’s based on the combination of the telescope’s entire optical system, particularly the focal length of both the telescope’s objective lens or mirror and the eyepiece. The magnification power of […]

A 0.9-inch Barlow lens is an optical device used in telescopes to increase the effective focal length of the telescope, thereby enhancing its magnification capabilities. A Barlow lens is typically a concave lens that is placed between the objective lens (or primary mirror) of the telescope and the eyepiece. The 0.9-inch specification refers to the […]
