Explore Scientific FE03-125 overview

  • 1Description

The 1.25" barrel diameter 3x Focal Extender from Explore Scientific triples the magnification of any 1.25" eyepiece, adding another layer of usability to the eyepieces you have. Additionally, since low-power eyepieces often offer a longer eye relief than high-magnification ones, using this focal extender gives you the benefit of comfortable viewing, while increasing the magnification. This extender features a fully multicoated 4-element optical configuration to produce bright images with true color representation without distortion across the entire field of view.

Effectively increases the magnification of any 1.25" eyepiece 3x
Four-element optical configuration with fully multicoated anti-reflective coatings
Double tapered barrel design allows for smooth insertion and removal into telescope focuser or eyepiece holder
Textured non-slip grip

    3x Focal Extender (1.25") is rated 3.0 out of 5 by 2.
    Rated 5 out of 5 by from 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.

    Rated 1 out of 5 by from 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.
