What is the advantage of the X-Cel LX 2x Barlow's 3-element design?
The 3-element apochromatic design provides superior color correction compared to simpler 2-element achromatic Barlows. This results in sharper, higher-contrast images with virtually no distracting color fringing, which is especially critical for high-magnification views of the Moon, planets, and double stars.
How will the Celestron X-Cel LX 2x Barlow perform with a 10mm eyepiece on Jupiter?
Using the X-Cel LX 2x Barlow with a 10mm eyepiece effectively gives you the view of a 5mm eyepiece, doubling your magnification. On a planet like Jupiter, this will make details like the Great Red Spot and individual cloud bands much larger and easier to resolve, while the apochromatic optics will ensure the planet's subtle colors remain true.
Can I use the X-Cel LX 2x Barlow for imaging?
Yes, this Barlow is an excellent choice for planetary imaging. By doubling the effective focal length of your telescope, it increases the image scale on your camera sensor, making planets appear larger. The sharp, color-corrected optics will help you capture fine details with a planetary camera.
Will this Barlow work with my 8" f/10 Schmidt-Cassegrain telescope?
Absolutely. The X-Cel LX 2x Barlow is a perfect match for an 8" SCT. It will double the magnification of your eyepieces, providing the high power needed to split tight double stars like Albireo (Beta Cygni) or examine crater details along the Moon's terminator, all while maintaining a sharp, clean image.
What is the benefit of the brass compression ring on the X-Cel LX Barlow?
The brass compression ring provides a more secure grip on your eyepiece than a standard thumbscrew. It applies even pressure around the eyepiece barrel, holding it firmly in place and preventing it from wobbling. It also protects your eyepiece barrels from being scratched or dented by the tip of a set screw.
Can I attach a filter to the X-Cel LX 2x Barlow?
Yes, the 1.25" barrel is threaded to accept standard 1.25" filters. This means you can attach a filter to the Barlow itself, and it will work with any eyepiece you insert. This is more convenient than moving a filter from one eyepiece to another when you want to change magnification.
