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

Product Information

Celestron’s FREE planetarium app is an astronomy suite that redefines how you experience the night sky.

Unlike traditional telescopes, the RASA design ingeniously places the imaging sensor at the front of the telescope tube, creating an ultra-fast f/2. 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. 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. The Barlow is simply placed in your focuser or star diagonal before the eyepiece and will suit virtually any telescope that accepts 1. We also felt that of all the Barlows we've tried with a brass compression ring, this was the smoothest for inserting our 17mm undercut eyepiece, giving an almost airtight seal even before we tightened the locking bolt.Like all Explore Scientific products, the 3x Barlow Focal Extender is supplied in a most attractive retail box. In Tele-Extended mode, the Barlow doubles the focal length and f/ratio of your telescope, resulting in an image on the sensor or film plane that is twice the size of a prime focus image. This is a good thing, because normally the shorter the focal length of the eyepiece, the less eye relief you have. The ED lens increases constrast and brightness to ensure the best possible view through any eyepiece.

With the Barlow element you can move the focal plane further out, eliminating this problem in most cases. ED stands for "extra-low dispersion," which refers to the composition and optical properties of the glass used for the lenses. Displaying a green tinge, the multicoated lens surfaces are blemish free, and the long body possesses micro-baffles with a good matt black finish throughout its length.It is easy to use; insert the eyepiece into the Barlow lens, then insert the Barlow lens into the scope. The removed Barlow lens cell can be screwed directly to any eyepiece, imaging camera or webcam fitted with a 1. I can't comment to much on this item as i have only just started to get into astronomy,but will say (the item appears to be well made ,and does what it is supposed to. Continue reading for an explanation of the individual values and you can also see a test report that was done on one of our RVO Horizon 60 OTAs. From a lunar and planetary imaging point of view, Powermates are the better choice as they can be stacked to produce high levels of magnification.

Amscope microscopes come with multiple magnifications to aid you in finding the proper magnification for viewing each specimen. EclipSmart solar products feature Solar Safe filter technology providing the ultimate protection from harmful solar radiation, including both IR and UV light, and filters 99.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. Star Procyon was sharp across the whole view with our 26mm eyepiece, although we did notice the slightest of distortions at the edge. 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. 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. Model: ae_2x_barlow_t This useful 2x Barlow incorporates a camera thread for photography and a removable Barlow lens cell.
