To find Polaris in the sky, look north and locate the pattern of the Big Dipper. These features combined with the included EQ-2 equatorial mount and included accessories described below make this one sweet optical system for astronomy! From this point on in your observing session, you should not make any further adjustments to the latitude of the mount, nor should you move the tripod. The latitude range refers to the usable range on the EQ mount's latitude axis. entityId: 114731, To clean the secondary mirror, first remove it from the telescope. As your eyes become dark-adapted, more stars will glimmer into view and you will be able to see fainter details in objects you view in your telescope. defaultImage: '', height: 90, You should not have to clean the telescope’s mirrors very often; normally once every other year or even less often. entityId: 103175, It has a multi-coated lens that lets in more light and allows you to enjoy higher-power, sharper images without eye strain. You will have to buy one separately. Another hint: Good seeing can vary minute to minute. Using a 2mm Allen wrench, loosen the three small alignment set screws in the center hub of the 4-vaned spider several turns. }, { It provides an easy way to transport and store your telescope. entityId: 99816, }, { The planets don’t stay put like stars do (they don’t have fixed R.A. and Dec. coordinates), so you will need to refer to the Orion Star Chart on our website. You will fix that when aligning the primary mirror. sourceURL:'/catalog/community_content_viewer_placeholder.jsp?productId=101755&isPDP=true', entityType: 'product' To see what you are doing in the darkness, use a red light flashlight rather than a white light. It may not be perfectly centered, but that is OK. Now tighten the three small alignment screws equally to secure the secondary mirror in that position. Then look again into the telescope’s eyepiece and see if it is still centered there too. For more detailed information on this topic see our Learning Center article: How to Choose a Telescope So give yourself at least a little while to get used to the dark before you begin observing. How do I point the telescope on an Equatorial Mount? }, { A carry case is not included in the purchase. layers: '05662' entityType: 'product' Light-polluted skies greatly reduce what can be seen with the telescope. 1. Our Verdict: The SpaceProbe 130ST EQ is a solid telescope with plenty of potential. It may help to have no reflections and align the secondary on the edge of the telescope wall. Printed on completely dew-proof durable plastic. width: 160, layers: '04150' The tilt angle of the rings varies over a period of many years; sometimes they are seen edge-on, while at other times they are broadside and look like giant “ears” on each side of Saturn’s disk. Telescopes on either very lightweight mounts or non tracking mounts (such as Dobsonians) are capable of only very short exposures such as lunar photographs. }, { The center mark is also required for best results when using other collimating devices, such as Orion’s LaserMate Collimator, obviating the need to remove the primary mirror and mark it yourself. It helps to adjust the secondary mirror in a brightly lit room with the telescope pointed towards a bright surface, such as white paper or wall. Alignment is easiest to do in daylight, rather than at night under the stars. Offering a wide 52° apparent field of view, the 25mm Sirius Plossl eyepiece yields extremely sharp images of impressively high contrast. Now, find the constellation in the sky. entityId: 4110, This neutral-density eyepiece filter reduces glare so you can see more detail and surface features. Be sure that it will not fall into the optical tube and hit the primary mirror. height: 160, width: 160, entityType: 'product' Keep in mind that at higher powers, an image will always be dimmer and less sharp (this is a fundamental law of optics). sourceSelector:'' Loosen the adjustment screws or pull on the tensioner (depending on the model) and rotate the finder scope tube in the bracket until the crosshairs are oriented the way you want. The practical limit is 50X per inch of aperture, or 120X for a typical 60mm telescope. Don’t worry that the reflection of the secondary mirror (the smallest circle, with the collimation cap “dot” in the center) is off-center. Mars makes a close approach to Earth every two years; during those approaches its disk is larger and thus more favorable for viewing. entityId: 99825, Standard achromatic refractors routinely use Crown and Flint for the two elements, but more expensive apochromatic refractors can use ED (extra low dispersion) glass for one or more of the lenses. Moreover, the secondary mirror is held in an advanced holder with thin 0.5mm metal vanes, to reduce diffraction spikes and light loss. This will give you the widest possible field of view. entityType: 'product' To starhop, only a minimal amount of additional equipment is necessary. entityType: 'product' In conditions of good “seeing”, star twinkling is minimal and objects appear steady in the eyepiece. Depending on the altitude of the object you want to observe, the counterweight shaft will be oriented somewhere between vertical and horizontal. Atmospheric conditions vary significantly from night to night, even hour to hour . With a large aperture and a fast f/5 focal ratio, you’ll have a nice wide field of view for stargazing and seeking out nebulae and other DSOs. }, { Our Verdict: The SpaceProbe 130ST EQ is a solid telescope with plenty of potential. A sturdier tripod would be an excellent upgrade to minimize shake and tremors, but the optics itself is fundamentally sound. }, { The mount cannot handle anything heavier like a DSLR camera, and if you were using an autoguider to counteract for the EQ2’s lack of precision, it’s out of the question. The perfect road-map style star atlas, DeepMap 600 includes color coded symbols for 500 galaxies, nebulars, star clusters, and 109 Messier objects. Is the SpaceProbe good for astrophotography? sourceURL:'/catalog/community_content_viewer_placeholder.jsp?productId=103175&isPDP=true', layers: '08711' With this handy laser collimator, you'll get fast, dead-on alignment (collimation) of your reflector telescope's optics. }, { width: 90, These coatings normally last through many years of use before requiring re-coating. width: 90, This is done by alternately loosening one of the three alignment set screws while tightening the other two. In metric units, this is: Resolving power (in arc seconds) = 116 divided by aperture of telescope (in millimeters). A good star to remember for this is Megrez (mag. }, { Choose an object with a visual magnitude of 9 or lower. defaultImage: '', A simple planisphere, or star wheel, can be a valuable tool for learning the constellations and seeing which ones are visible in the sky on a given night. Any quality optical lens cleaning tissue and optical lens cleaning fluid specifically designed for multi-coated optics can be used to clean the exposed lenses of your eyepieces or finder scope. The tube itself is 6.2 lbs with a short length of 24”. layers: '05598' But anyone with the slightest technical bent will have no problem getting familiar with these models. Now, try tightening or loosening one of the larger collimation screws with your fingers Look into the focuser and see if the secondary mirror reflection has moved closer to the center of the primary. sourceSelector:'' This is due to the fact that the exit pupil of the telescope (the beam of light exiting the eyepiece) is now larger than the average person's dark adapted pupil, and no more light can fit into the eye. The EQ2 is a manual equatorial mount with setting circles and slow-motion hand controls. It is not possible to correct the image orientation in a reflector telescope. Orion offers a rugged, fully padded case to fit just about every telescope we stock. Try using an Orion Moon filter to dim the Moon when it is too bright; it simply threads onto the bottom of the eyepiece, you’ll see much more detail. The highest practical limit is different from the often used "highest theoretical magnification" specification. No surface markings can be seen on Venus, which is always shrouded in dense clouds. That brings us to sweet. One good way to tell if conditions are good is by how many stars you can see with your naked eye. div.kids_pdp h4 {margin: 0 0 2px 120px;} Limited Warranty against defects in materials or workmanship for one year from date of purchase. 25mm Orion Sirius Plossl telescope eyepiece (1.25") Good “transparency” is especially important for observing faint objects. A dual-axis motor drive is necessary for astrophotography. For the novice stargazer, buying a computer-controlled telescope with a small aperture puts a lot of money into the mechanical and database components of the telescope to locate objects that you can’t see with the optics of the telescope. width: 160, When you observe a celestial object through the telescope, you’ll see it drift slowly across the field of view. This time, be sure the stars indicated on the star chart are in fact the stars you are centering in the finder scope and telescope eyepiece. The R.A. setting circle must be re-calibrated every time you wish to locate a new object. sourceURL:'/catalog/community_content_viewer_placeholder.jsp?productId=99816&isPDP=true', }, { Someone who is inexperienced with astronomy and night sky will spend their time pouring over instruction manuals and text scrolling across a screen instead of exploring the night sky, studying the stars and their patterns and learning how to locate to binary stars and nebula. For viewing craters on the Moon, the rings of Saturn, and Jupiter with its four bright moons, a 60mm or 70mm refractor or a 3-inch reflector telescope does a good job.
