About this product

Model: es_1.25inch_2x_barlow
Part Number: 0218750

Explore Scientific premium 1.25" 2x / 3x / 5x Barlow / Tele-Extenders are an excellent choice for visual observations and astrophotography.

With tele-extenders it is possible to extend the effective focal length of a telescope system, resulting in higher magnification for the observation of the moon, the planets or small Deep-Sky objects with the same eyepieces. So you can use the advantages of eyepieces with longer focal length - such as the bigger eye distance and the more relaxed observing comfort - at high magnifications also.

These tele-extenders incorporate a tele-centric optical design that delivers a excellent image sharpness over the whole field of view and are premium choices for visual observations and astrophotography. The combination of excellent fully multi-coating with superior optical design makes the Focal Extenders superior to classic Barlow lenses.

ES 2x 1.25” tele extender

15 June 2022 | Ian

A top quality tele extender from Explore Scientific in the 1.25” size. Really well made and is a substantial piece of equipment. The images are nice and clear without any aberrations. The extender is better for stopping vignetting over the Barlow lens. Definitely a good buy. Top service from FLO again

What a difference!

07 October 2020 | Jamie

I used this x2 focal extender with my C9.25 last night to image Mars at close approach. What a difference to the basic x2 Barlow that I was using. No significant light loss, or colour dispersion or reflections which I was having previously. Last nights data is the best I've had. I also tried imaging the craters on the moon as a test, and couldn't believe the improvement. Overall I'm very happy with this focal extender.
