Explore Scientific 1.25" 5x Focal Extender (1.25")
Key Features
  • Increases Eyepiece Magnification 5x
  • Fits 1.25" Holders and Accessories
  • 4-Element Optical Configuration
  • Fully Multi-Coated Optics
Built with a 1.25" nosepiece that fits the most popular size of drawtubes, focusers, and diagonals, the 1.25" 5x Focal Extender from Explore Scientific increases the power of any 1.25" eyepiece by a factor of five, adding another layer of usability to the eyepieces you have. Additionally, since long focal length (low-power) eyepieces often offer a longer eye relief than short focal length (high-magnification) ones, using this focal extender gives you the benefit of comfortable viewing while enjoying high-power observations. The extender has a fully multi-coated 4-element lens configuration to produce bright images with true color representation without distortion across the entire field of view, and the edges of the lenses are blackened to further improve contrast.

Great for telescopes with a short focal length

By Chris-PA
Rated 5 out of 5

If you have a reflector or a refractor with a short focal length (under 1000mm), this is a very useful, high-quality Barlow - especially if you want to image planets with a CCD camera. My results have been great so far - much better than what I was able to do with a 2x. If you have a Schmidt- or Maksutov-Cassegrain, this is going to be overkill. I also wouldn't recommend it if you have a single-speed focuser; you really need to be able to fine-tune things to get this to work.
