Explore Scientific: 2x Explore Scientific Focal Extender; 2-inch Barrel; 4 Elements.
This 2'' Focal Extender from Explore Scientific offers 2X magnification, and comes with a 1.25'' compression adapter. Explore Scientific Focal Extenders are great for either visual or imaging use. Insert them before the diagonal or after the diagonal and get the same magnification regardless. For imaging, you can introduce the focal extender anywhere between the telescope and the camera, allowing you to add an accessory like a filter wheel without worrying about changes in magnification.
All Explore Scientific Focal Extenders are fully multi-coated and each element has blackened edges for increased contrast and prevention of internal reflections.
A good Focal Extender adds some real versatility to your telescope accessory line-up. First of all, it allows you to increase the magnification of any eyepiece with the same barrel size that you already own. In other words, 3 eyepieces offer 6 magnification choices with the addition of a focal extender. Secondly, most of the time, lower magnification eyepieces have better eye relief than higher power models. When using a focal extender to increase your magnification, you get to enjoy the generous eye relief of the lower power eyepiece, and that's quite a bonus, especially for eyeglass wearers or for those with fast telescopes who can really push high magnification eyepieces. Remember, we make focal extenders in 2X, 3X and 5x models, so there is something for every style of telescope.
