Celestron 93326 Omni Barlow Lens, Silver, 2 x 1.25 Inch

Product Information

These are values which ideally would be at 0 but as our test optics are all curved lenses, there will always be astigmatism and coma present. The PV rating (Peak To Valley) is a measurement from the highest point (Peak) to the lowest point (Valley). Within the interferometer is a calibrated laser that is pointed through the optical test surface, then onto a high quality reference sphere, then back through the test subject then to an internal camera which gives us the measurement on the screen. Typical Barlows have a magnification of 2x and are composed of two or sometimes three elements in a single group, forming a negative lens. The 2x Achromatic Barlow lens doubles the magnification of an eyepiece, without any noticeable loss in image quality.

field of view: with the Orion Nebula in the centre we could fit double star Struve 747 near the edge of the view. As a bonus, the increase in the scope’s focal ratio can improve image sharpness, but only under ideal conditions. We are using the very latest Zygo MX software to provide a more detailed report compared to other standard reports.Now, Celestron is using that same technology to allow star gazers to connect to the night sky and enhance their experience of the cosmos in fun and unique ways. When you use a Barlow lens with an eyepiece, you get double the magnification, but the eye relief is not affected. You calculate the magnification of a telescope by dividing its focal length by the focal length of the eyepiece. This Vixen 2x Barlow lens is ideal for observing and photographing lunar landscapes and details on the brighter planets.

T-threads on the top of the adapter screw into a T2 mount (sold separately) that is designed to attach to the brand-specific lens mount of your DSLR or SLR camera. Add a Celestron Omni 2X Barlow Lens to the mix, and now you have four magnifications to choose from. A 2x barlow lens doubles the magnifying power of your eyepiece by doubling its effective focal length.With the Barlow lens cell removed - the remaining body and nosepiece can be used as a straightforward, non-magnifying camera adapter or a 1. inch eyepiece into the chamber and you will enjoy double the magnification, while retaining all the eye relief of the inserted eyepiece.

Their precise corrections for spherical and chromatic aberrations at all photo-visual wavelengths result in sharp, high-resolution performance on telescopes of any optical design. If one is inserted into the light path of any type of scope, the effective focal length of the scope is increased. adaptor are designed with a brass compression ring to securely hold eyepieces and protect the eyepiece barrel from scratches. Just point the telescope at any three bright objects—stars, bright planets, or even the Moon—and your telescope can orient itself with the night sky.eyepieces, t-adapters and other accessories, giving you flexibility of use and the ability to vary magnification in different accessories. The lower lens housing is threaded to accept standard filters and the screw for holding the eyepiece doesn't unscrew the whole way, meaning it shouldn't fall out and get lost in the dark. At the forefront of a new era in amateur astronomy, the launch of Celestron Origin stands as a beacon, seamlessly intertwining stargazing and astrophotography into a singular, user-friendly experience. It has a middling weight of the lenses reviewed at 165g, and the body is elegantly designed, with a silver undercut lens barrel and chunky rubber grip. In the 1960s, Celestron’s founder, Tom Johnson, created groundbreaking new telescopes never before seen on the consumer market.

The barlow did a good job on our test subjects, which also included the Moon and Venus as well as our deep-sky objects. Amscope microscopes come with multiple magnifications to aid you in finding the proper magnification for viewing each specimen.The 2x Barlow lens doubles the magnification with any given eyepiece, without any noticeable loss in image quality.
