Manufacturer Description

This high performance Antares barlow # UB1.5STL will multiply the power of any inserted eyepiece by a factor of 1.5x. It features a fully-multicoated achromatic design. This short barlow will work in diagonals or reflectors, has has internal darkening and edge-blackened lenses. Suitable for high contrast, medium power applications in any telescope.

Note that the use of any optical element like barlows and focal reducers changes the focus point of your telescope, requiring additional in-focus or out-focus travel. The exact amount of focus travel required will depend on the optics and mechanics of your specific set-up (telescope, diagonal (if used), barlow, and eyepiece). Hence, be aware that you may not be able to reach focus with all eyepieces or in all configurations with a given barlow.
