When selecting a Barlow lens for the Orion Skyscanner 100, it’s vital to consider the existing focal length and desired magnification. The Orion Skyscanner 100 is a short-tube reflector telescope with a focal length of 400mm, making it well-suited to wide-field observations. A 2x Barlow lens will effectively double the magnification of your eyepiece, while a 3x Barlow will triple it.
A highly recommended model is the Celestron X-Cel LX 2x Barlow lens. This lens features fully multi-coated optics that enhance light transmission, a compression ring to prevent marring of eyepiece barrels, and an integrated T-thread for camera connections if astrophotography is your goal. It provides quality performance without degrading the view, making it a solid choice for the Skyscanner 100.
Another excellent option is the Tele Vue 2x Barlow. Known for their high-quality optics, this Barlow lens maintains edge-to-edge sharpness and delivers superior image brightness. While it might be a more premium choice, the optical quality can significantly enhance viewing experiences, especially for focusing on planets and lunar details.
When using a Barlow lens, remember that increasing magnification can also magnify any atmospheric instability or imperfections in the telescope’s optics. For the best experience, ensure your telescope is properly collimated and that observing conditions are favorable.
