By using Barlow lenses, the basic optical magnification of telescopes can be increased, and thus the observed objects can be viewed with greater magnification.
Due to their two lens design, these Barlow lenses provide a brilliant image quality for the whole visual field and are suitable for observations and photography. The BRESSER Barlow lens has a diameter of 31.7 mm/1.25", the thread is the same as the 1.25" filters, so it is compatible with 1.25" eyepieces, can be assembled with t-adapters and other accessories, which provides enough flexibility for use.
