Digital Cameras Photo Reviews of Orion 20mm Illuminated Centering Telescope Eyepiece
Customer Review: Great product if only it were not so bright
Summary: 3 Stars
I bought this eyepiece in the summer of 2009, to use for centering the alignment stars in my goto telescope. It works well because it has a wide field of view, so it is easy to find the alignment star you are looking for. But the illuminated reticle is much too bright, even on its dimmest setting. So under dark skies, the glare of the red light of the reticle washes out the stars in the field, making it very hard to see the stars you are trying to center. There are several reviews on the Orion website that complain of this same problem, but unfortunately those reviews were not yet up when I bought the product right after it came out.
I called Orion tech support and they said others have called with this same complaint. They recommended that I put a piece of opaque tape over the red light, to dim it. I tried this and it helps a little bit. But it is hard to make the piece of tape big enough to do enough dimming, and yet small enough to fit into the little space available, and hard to get it to stay in place.
If Orion comes out with a newer version of this eyepiece with a dimmer light, it would be a great product.
Description of Orion 20mm Illuminated Centering Telescope Eyepiece
You'll never be left in the dark with the Orion 20mm Illuminated Centering Eyepiece (ICE). Whether you're acquiring and centering stars for GoTo system alignment, lining up guide stars and/or target objects for astro-imaging, or just testing the accuracy of your tracking system, the ICE will quickly become one of your most trusted and useful imaging tools. In comparison to most standard low-focal length illuminated reticle eyepieces, the ICE offers a relatively long 20mm focal length and a wide 70-degree apparent field-of-view, making it easier to locate desirable targets for alignment or guiding. This virtually eliminates the need for swapping out high-power illuminated reticles with lower power eyepieces in order to center objects. The Illuminated Centering Eyepiece is fully multi-coated (all air-to-glass surfaces) with anti-reflection coatings for bright, crisp views. It features a great 16mm eye relief and the barrel is threaded for Orion 1.25" filters. The illuminator switch doubles as a dimmer allowing you to adjust cross-hair brightness to the desired level. The illuminator is powered by two LR-44 batteries (included) and weighs in at 8 oz. One-year limited warranty.Eyepieces
