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

Product Information

In other words, a standard 10mm eyepiece, as a general rule, will have better eye relief than a 5mm eyepiece. This is a brand new 2X Barlow (auxiliary objective) lens for AmScope SM and SW series stereo microscopes.

It is ideal for high powered viewing of the moon and planets when using refractor or reflecting telescopes. This innovative software solves the time-consuming problem of trying to pinpoint the North Celestial Pole. 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 built in T thread allows cameras to be attached with a T ring and will double the focal length of your telescopes increasing the image scale of your astro images.The 2x Achromatic Barlow lens doubles the magnification of an eyepiece, without any noticeable loss in image quality. Unlike traditional telescopes, the RASA design ingeniously places the imaging sensor at the front of the telescope tube, creating an ultra-fast f/2. Celestron’s X-CEL LX 3x Barlow is designed to be the perfect companion to the company’s range of X-Cel LX eyepieces, with a matching rubber grip pattern, copper-coloured banding and an all black silk finish.

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. Once the measurement has been taken, we are provided with a series of results that show the optical quality of the surface plus other information. 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. The Celestron Universal Barlow and T-Adapter can also be used for prime focus photography, which means you use the telescope as a very big photographic lens. The soft rubberised material of the dust caps for both barrel and eyepiece holder made for a pleasant change from plastic inserts.One of the most important factors in a telescope is its transmission—the percentage of light that reaches the focal plane. use the T-Adapter with the barlow lens along with a relevant T2 mount (not included) for tele extended photography. Again, these are measured by the interferometer when we take measurements of the optical surface after adjustment. A Powermate is a telecentric design with four lenses in two doublet groups: a smaller negative lens and a larger positive lens arranged so that light exits the Powermate in parallel rays. More than 15,000 Baader planetariums (the company’s first patented product) help students around the world to understand astronomical relationships.

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. This three-element multicoated design places the lower lens element at the very base of the barrel, meaning it does not include a filter thread.

Due to their two lens design, these Barlow lenses provide a brilliant image quality for the whole visual field and are suitable for observations and photography. Just insert the Barlow lens between the eyepiece and the telescope and you will double the magnification. 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.
