Celestron Omni 2X Barlow Lens
Celestron Omni 2X Barlow Lens
A Barlow lens is the astronomy accessory that keeps on giving! Insert it between your eyepiece and your telescope to get double the magnification instantly. Let’s say you have two eyepieces in your accessory case, a 10 mm and a 25 mm. Add a Celestron Omni 2X Barlow Lens to the mix, and now you have four magnifications to choose from. Combining this lens with the 25 mm provides double the magnification, or the equivalent of a 12.5 mm eyepiece, while the 10 mm gives you the power of a 5 mm eyepiece. Eye relief is the distance your eye has to be from the first lens in the eyepiece in order to see the full field of view. When you use a Barlow lens with an eyepiece, you get double the magnification, but the eye relief is not affected. This is a good thing, because normally the shorter the focal length of the eyepiece, the less eye relief you have. In other words, a standard 10mm eyepiece, as a general rule, will have better eye relief than a 5mm eyepiece. Bonus! The Celestron Omni 2x Barlow comes in a sleek, silver package. The two-element optics are fully multi-coated, and the edges of the lenses are blackened to cut down on internal reflections. The 1.25” barrel will fit in standard 1.25” focusers and diagonals, and the Barlow will accept 1.25” eyepieces. A metal thumbscrew locks the eyepiece firmly in place.

Celestron 93428 X-Cel LX 1.25-Inch 3x Barlow Lens (Black)
Celestron 93428 X-Cel LX 1.25-Inch 3x Barlow Lens (Black)
When inserted between the eyepiece and telescope, this premium 3x Barlow lens triples the magnification of all your 1.25” eyepieces. This is a perfect accessory for owners of short, fast telescopes, and is especially helpful for boosting the magnification during lunar or planetary observations under good seeing conditions. The apochromatic, fully multi-coated optics offer great color correction and contrast. The black anodized housing with orange highlights matches the eyepieces in the Celestron X-Cel LX line. A centralized rubber grip helps to keep your hands securely on the barrel, even when your fingers are cold or you are wearing gloves. A brass compression ring just inside the top of the X-Cel Barlow grabs your eyepiece gently but firmly when you turn the thumbscrew. Once the thumbscrew has been secured in place, the brass ring keeps your eyepiece in the Barlow instead of relying on the tip of the thumbscrew itself, offering a better and protecting the barrel from scratches. The barrel of the Celestron X-Cel LX 3X Barlow is threaded to accept 1.25” filters, allowing you to change eyepieces without requiring you to remove and re-attach the filter from each eyepiece barrel.

Celestron Eyepiece and Filter Kit - 14 Piece Telescope Accessory Set
The Celestron 1. 25 Eyepiece and Filter Kit is a great way to expand the functionality and enjoyment of your telescope. Inside the metal, foam-lined carry case you'll find these accessories: 32 mm Plossl Eyepiece - 1. 25 17 mm Plossl Eyepiece - 1. 25 13 mm Plossl Eyepiece - 1. 25 8 mm Plossl Eyepiece - 1. 25 6 mm Plossl Eyepiece - 1. 25 2X Barlow Lens - 1. 25 #80A Blue Filter - 1. 25 #58 Green Filter - 1. 25 #56 Light Green Filter - 1. 25 #25 Red Filter - 1. 25 #21 Orange Filter - 1. 25 #12 Yellow Filter - 1. 25 Moon Filter - 1. 25 Eyepieces - All five Plossl eyepieces can be used in any telescope with a 1. 25 focuser. Each eyepiece features a four-element design with a 52º apparent field of view. The optics are fully multi-coated to improve light transmission and protect the optics. The 32 mm Plossl eyepiece offers a low power, wide field view in most telescopes, the 13 mm & 17 mm focal lengths are good medium-power oculars, and the 8 mm & 6 mm eyepieces provide high magnifications, great for the Moon and planets, especially when seeing conditions are good. 2X Barlow Lens - The included, and very versatile 2X Barlow doubles the magnification of any 1. 25 eyepiece. Since this kit includes five (5) eyepieces, you will be able to use them with and without the Barlow, giving you a total of ten magnification options in all. Any other 1. 25 eyepieces you already have will also work in this desirable accessory, giving you even more magnification choices. Remember, high magnifications do not always produce clear, sharp results, especially on evenings of poor or moderate seeing conditions. Experiment to find the magnifications that are best for your telescope on a particular night. Filters - Colored filters can be used to bring out certain details on a planets surface or its cloud structure. All of the planetary filters included in the 1. 25 Eyepiece & Accessory Kit, as well as the Moon filter, can be used on any 1. 25 eyepiece with the proper filter threads, so they are v... [Read More]

Orion 08711 Shorty 1.25-Inch 2x Barlow Lens (Black)
Orion 08711 Shorty 1.25-Inch 2x Barlow Lens (Black)
Give your telescope eyepieces a 2x power boost! The Orion Shorty 1.25 inch 2x Barlow Lens doubles the power of any 1.25 inch telescope eyepiece it's used with. For about the price of a single eyepiece or less, the practical Shorty 2x Barlow effectively doubles the number of telescope eyepieces at your disposal. The Orion Shorty 2x Barlow Lens doubles the magnifying power of any 1.25 inch eyepiece, essentially dividing the eyepiece's focal length by a factor of 2. For example: using a 25mm eyepiece in the Shorty 2x Barlow provides the same magnification a 12.5mm eyepiece would normally exhibit (25 / 2 = 12.5). Using this simple formula, you can easily determine how each of your 1.25 inch telescope eyepieces will perform when inserted in the Shorty 2x Barlow Lens. A 20mm ocular will behave like a 10mm eyepiece; a 6mm eyepiece will provide the magnification of a 3mm eyepiece, and so on. Using the Orion Shorty 1.25 inch 2x Barlow Lens is easy. Simply insert the Shorty 2x Barlow into your telescope's focuser or diagonal, and then insert any 1.25 inch eyepiece into the Orion Shorty, gently securing it in place with the two thumbscrews. Then, adjust the telescope's focus wheels to enjoy double the magnification of the eyepiece used. Think of the money you can save with this practical and affordable telescope eyepiece accessory! Not only does the Orion Shorty 2x Barlow's power-boosting ability mean you can enjoy two different viewing magnifications with each 1.25 inch telescope eyepiece in your collection, the Shorty Barlow can also make observing at high powers more comfortable. Many low focal length high-power eyepieces have a woefully small eye lens that can be troublesome to peer through, especially for eyeglass wearers. Using the Orion Shorty 2x Barlow Lens with a longer focal length eyepiece lets you achieve the same high magnification view, but in most cases the eye lens will be much larger, helping to reduce eye strain and improve comfort.
