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

Product Information

This innovative software solves the time-consuming problem of trying to pinpoint the North Celestial Pole.

The most important factor in ensuring successful microscopic imaging is choosing the appropriate optics and camera for your application that gives you more data and higher image quality. The lenses are fully coated and housed in a quality aluminium body with a rubber grip ring and blackened 2" barrel to prevent unwanted internal reflections. It incorporates high quality optics with apochromatic characteristics, for magnifications of 2x and above.All goods are shipped with UPS, DPD, DHL, DX Express, ParcelForce and Royal Mail, we do not use budget couriers, we only ship to UK mainland addresses and do not ship to forwarding agents or PO boxes.

This can be very useful when trying to get to photographic focus with some Newtonians and Solar Telescopes, which lack the necessary amount of in focus travel to get a camera to a prime focus position. I have only used this Barlow a few times so far but it seemed to do a good job when I used it to observe Mars with good detail when the seeing allowed. adaptor are designed with a brass compression ring to securely hold eyepieces and protect the eyepiece barrel from scratches. Both Barlow lenses and Powermates act as image amplifiers by increasing the effective focal length of your telescope, thereby increasing the magnification achieved with any eyepiece.Typical Barlows have a magnification of 2x and are composed of two or sometimes three elements in a single group, forming a negative lens. This high quality 2" barlow lens has extra low dispersion or ED optics to improve corrections and contrast over ordinary achromat optics. Subsequently, you can use lower power eyepieces in Barlows to act as much more powerful eyepieces, but retain the larger ocular size and more comfortable viewing that comes with lower power eyepiece designs.

Eyepiece will increase the magnification of the eyepiece by 2 times, thereby making it easier to spot detail in the surface of the nearest planets. This design ensures that the original eye relief of the eyepiece remains unchanged, making it more suitable for longer focal length eyepieces and avoiding the risk of vignetting. There are two retaining thumbscrews to hold the eyepiece in place, but there is no anti-marring compression ring.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. For example, an 18mm eyepiece used with a 2x Barlow lens would have the magnifying power of a 9mm eyepiece. Barlow x2 lense This was my second purchase from Harrisons and once again the quality and service was first class.
