High quality barlow lens that features twist lock
This barlow lens features a twist lock mechanism which makes your eyepiece/camera centralized. This makes more of the stars focused so it is far better for astrophotography. Objects that are in the center of the field are more likely to be pin points.
This high-performance Antares Barlow features large 26mm-diameter optical elements (great for use with a wide range of eyepieces) and a fully multi-coated achromatic design with edge-blackened lenses for maximum contrast. The 'short' design ensures that it will work with star diagonals. The Barlow is ideal for use with low-powered (long focal length) eyepieces to deliver higher powers, but with maximum eye-relief and viewing comfort. It is also very useful for webcam imaging and other astro-photographic applications. This super-quality Barlow achieves high-powered views with a high standard of colour correction ideal for planetary and lunar observing.

All barlows change the focus point of your telescope. This amount depends on the exact combination of your telescope, barlow, eyepiece and other optical accessories. Please note that you may not be able to reach focus with all eyepieces when using a barlow.
