Increase the Magnification of Your Eyepieces

Use this premium Barlow lens between your eyepiece and telescope. This will increase the magnification without noticeable loss of optical quality. In comparison, a poorly corrected achromatic lens would decrease the contrast. The Barlow lens can therefore also be used as an alternative to having an additional eyepiece. The advantage is that you still have the better eye relief of an eyepiece with a longer focal length, meaning you can always observe in comfort.

4 Lenses: For Top Quality Planetary Photos

This Barlow lens is also just about perfect for planetary photography. As optical quality here is critical, you should really use a high-quality Barlow lens. Without a Barlow lens planets appear tiny and virtually no detail can be seen. Only by inserting the Barlow lens can planetary images be made to appear a reasonable size. The better the correction of the lens, the better and sharper the image of the planet will appear. So the Alstar apochromatic Barlow has four lenses to ensure excellent correction and a pin-sharp, high-contrast image.
