Takahashi Extender-C2X

This is a Barlow lens designed to increase your telescope's effective focal length, which in turn boosts magnification. It allows you to get a closer look at celestial objects without needing to switch to a shorter focal length eyepiece.

Yes. While it is engineered to Takahashi's high standards, the 2-inch connection interface makes it compatible with a wide range of telescope designs, including reflectors, refractors, and catadioptric systems like Schmidt-Cassegrains.

The 73mm back focus is the distance required between the extender and your camera sensor or eyepiece to achieve proper focus. You will need to ensure your imaging train or eyepiece setup can accommodate this distance to avoid focus issues.

Because this unit uses high-quality glass optics, it is designed to maintain image sharpness and contrast. However, as with any optical element added to your light path, you may notice a slight dimming of the image due to the increased magnification, which is a standard trade-off.

It is suitable for both. The high-quality glass construction makes it a capable tool for planetary imaging where extra magnification is needed, provided your telescope's focal ratio and sensor size are compatible with the 73mm back focus requirement.
