Barlow

A Barlow lens is an optical accessory used in astronomy to increase the focal length of a telescope, which amplifies the magnification of the image. It is placed between the eyepiece and the telescope and is commonly used to obtain more detailed views of celestial objects without changing the eyepiece. Barlow lenses are valued for their ability to provide sharp and clear images while being a cost-effective way to enhance the capabilities of your observing equipment.
