Resumen del manual


If you look into the eyepiece adapter (without an eyepiece) at the top of the focuser, this is what you should see. If the reflection of your eye is off center, then collimation is necessary. Adjustments to the collimation of the telescope can be made by turning the collimation adjustment knobs located at the rear of the optical tube. First loosen the three Phillips head screws on the rear cell of the tube. Turn each collimation knobs, one at a time, until the reflected image of your eye in the secondary mirror is centered in the primary mirror. Once the telescope is collimated, tighten the Phillips head screws until you feel a slight resistance. Do not over tighten the screw. If your telescope is out of collimation, the best way to re-collimate it is with a good collimation tool. Celestron offers a Newtonian Collimation Tool (#94183) with detailed instructions that make it an easy chore. The view of a collimated telescope as seen through the focuser of the NexStar 114/130 reflector models. 31 You will find that additional accessories enhance your viewing pleasure and expand the usefulness of your telescope. For ease of reference, all the accessories are listed in alphabetical order. Adapter, Car Battery (#18769) -Celestron offers the Car Battery Adapter that allows you to run the NexStar drive off an external power source. The adapter attaches to the cigarette lighter of your car, truck, van, or motorcycle. Barlow lens, OMNI 1.25" (#93326) -Double the magnification of any of your Celestron eyepieces with this fully multi-coated, low profile Barlow lens Carrying Case, Soft NexStar 60/80/102 (#302160) -Lightweight yet durable, this nylon case is ideal for transporting your NexStar telescope. The shoulder and back straps provide hands-free convenience to make carrying your telescope anywhere even easier. Erect Image Diagonal (#94112-A) -This accessory is an Amici prism arrangement that allows you to look into the telescope at a 45° angle with images that are oriented properly (upright and correct from left-to-right). It is useful for daytime, terrestrial viewing with the NexStar 60, 80 and 102 Eyepieces -Like telescopes, eyepieces come in a variety of designs. Each design has its own advantages and disadvantages. For the 1-1/4" barrel diameter there are four different eyepiece designs available: • OMNI Plossl -Plossl eyepieces have a 4-element lens designed for low-to-high power observing. The Plossls offer razor sharp views across the entire field, even at the edges! In the 1-1/4" barrel diameter, they are available in the following focal lengths: 4mm, 6mm, 9mm, 12.5mm, 15mm, 20mm, 25mm, 32mm and 40mm. • X-Cel - This 6 element design allows each X-Cel Eyepiece to have 20mm of eye relief, 55° field of view and more than 25mm of lens aperture (even with the 2.3mm). In order to maintain razor sharp, color corrected images across its 50° field of view, extra-low dispersion glass is used for the most highly curved optical elements. The excellent refractive properties of these high grade optical elements, make the X-Cel line especially well suited for high magnification planetary viewing where sharp, color-free views are most appreciated. X-Cel eyepiece come in the following focal length: 2.3mm, 5mm, 8mm, 10mm, 12.5mm, 18mm, 21mm, 25mm. • Ultima -Ultima is not really a design, but a trade name for our 5-element, wide field eyepieces. In the 1-1/4" barrel diameter, they are available in the following focal length: 5mm, 7.5mm, 10mm 12.5mm, 18mm, 30mm, 35mm, and 42mm. These eyepieces are all parfocal. The Eyepiece and Filter Kit (#94303) – contains Five Superior Grade Plossl Eyepieces 1.25”. Barlow Lens - 2x 1.25”. Six Colored Eyepiece (Lunar & Planetary) Filters. Moon Filter. Aluminum Carrying Case Flashlight , Night Vision - (#93588) - Celestron’s premium model for astronomy, using two red LEDs to preserve night vision better than red filters or other devices. Brightness is adjustable. Operates on a single 9 volt battery (included). Filter, Light Pollution Reduction –UHC/LPR (#94123) - These filters are designed to enhance your views of deep sky astronomical objects when viewed from urban areas. LPR Filters selectively reduce the transmission of certain wavelength of light, specifically those produced by artificial lights. This includes mercury and high and low pressure sodium vapor lights. In addition, they also block unwanted natural light (sky glow) caused by neutral oxygen emission in our atmosphere. UHC?LPR Filter - #94123 32 Filter, Solar - The AstroSolar® filter is a safe and durable filter that covers the front opening of the telescope. View sunspots and other solar features using this double-sided metal coated filter for uniform density and good color balance across the entire field. The Sun offers constant changes and will keep your observing interesting and fun. PowerTank (#18774) – 12v 7Amp hour rechargeable power supply. Comes with two 12v output cigarette outlets, built-in red flash light , Halogen em...
