All about the Barlow Short 5x Kepler lens (4 elements) flowing 31.75mm
A Barlow lens (named after its inventor Peter Barlow) is a diverging lens that artificially multiplies the focal length of an instrument. This Barlow Kepler is composed of a high quality apochromatic quadruplet limiting chromatism. It will allow you to multiply by 5x the magnification of your eyepieces at the 31.75mm flow. Used in imaging, it gives the possibility of increasing the focal length to increase the size of the planets on your sensor, for example.
