Explore Scientific 1.25" 3x Focal Extender (1.25")
Key Features
  • Increases Eyepiece Magnification 3x
  • 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" 3x Focal Extender from Explore Scientific triples the power of any 1.25" eyepiece, 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.

very good for the price

I have used an xcel 3x Barlow for imaging solar system objects and also for visual observing, since about 5 years. Felt the need to try out a focal extender this time. This seems to be widely recommended and hence purchased this. I am quite happy with the results I am getting. The build quality seems to be great for this price point. Very happy with this!

Still waiting to use my new telescope

I would love to review this focal extender. However, I haven't been able to use it with my new 127mm FCD100 refractor due to an issue with the collar that holds the diagonal. I need to add an extender to bring the scope to focus. Unfortunately, the collar won't unscrew. And, Explore Scientific's support staff isn't responding to the case I have logged. This could be a great focal extender. But, if it can't be used due to equipment failure, it's essentially useless.

Excellent 3x barlow

I ordered this product to multiply magnifications of my eyepieces. I tested it for planets and double stars at very high magnifications, and really like the product. The green color coating looks great. I think $ is a bargain for a four element 3x barlow. B&H shipped really quickly. Overall, I like the B&H service and price, and I highly recommended this 3x barlow.
