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. defaultImage: '', Add the Orion 09007 SpaceProbe Black 130ST Equatorial Reflector Telescope on your list. Orion SpaceProbe 130ST Equatorial Reflector Telescope. entityId: 114731, Does the atmosphere play a role in how good the quality of the image will be? Very good optical and mechanical quality. The goal is to center the primary mirror reflection in the secondary mirror. sourceURL:'/catalog/community_content_viewer_placeholder.jsp?productId=99821&isPDP=true', A carry case is not included in the purchase. For telescopes, the optical diameter (also known as aperture) is the size of a telescope's main light-collecting lens or primary mirror, measured in millimeters or inches. Orion SpaceProbe 130ST Equatorial Reflector Telescope The Orion SpaceProbe 130ST reflector telescope is perfect for the more serious beginner or intermediate stargazer. entityId: 8711, Observing Hint: Always use your lowest powered eyepiece in your telescope when starhopping . It is not intended to remove or restrict your other legal rights under applicable local consumer law; your state or national statutory consumer rights governing the sale of consumer goods remain fully applicable. Choose an object with a visual magnitude of 9 or lower. Counterweight shaft sourceSelector:'' Spherical mirrors paired with the right focal length perform just fine, but with a short one as this, image and focus issues would be annoyingly apparent. To calculate the magnification, or power, of a telescope with an eyepiece, simply divide the focal length of the telescope by the focal length of the eyepiece. Red light will not spoil your dark-adapted night vision as readily as white light will. As an EQ mount, you can easily track bodies in the sky with the hand controls, and this model is available for upgrade with a separate purchase of a clock drive for hands-free tracking. height: 90, You can see the disk of the giant planet and watch the ever-changing positions of its four largest moons, Io, Callisto, Europa, and Ganymede. height: 90, }, { The Orion SpaceProbe 130ST EQ Reflector Telescope is a step up from the standard SpaceProbe 130 EQ for the more serious beginning or intermediate stargazer who wants additional performance, particularly for targeting deep-sky objects. entityType: 'product' Its primary mirror is parabolic, so there will be little to no noticeable aberration. This will prevent any tap water dissolved solids from remaining on the mirror. Cassegrain telescopes routinely use spheres in addition to other lenses in the optical path to correct for residual spherical aberration. Also, seeing conditions are typically poor during the day. entityId: 102697, entityType: 'product' Always start viewing with your lowest-power (longest focal length) eyepiece in the telescope. According to market research, Orion Spaceprobe 130ST is probably the most wanted Equatorial Reflector Telescope that Orion has to offer. Designs range from a standard air-spaced doublet (two lenses in a row) to exotic designs such as oil-spaced triplets and 4-element multi group lenses. Before you buy, consider carefully a telescope’s size and weight. . 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. entityId: 99799, Visit the Orion Community Center for in-depth information on telescopes, binoculars, and astrophotography. width: 200, Except for the Moon and the brighter planets, it is pretty time-consuming and frustrating to hunt for objects randomly, without knowing where to look. Space Probe 130 ST parts diagram Dovetail slot Finder scope Alignment thumb screws(2) Spring-loaded ⦠}, { width: 90, sourceURL:'/catalog/community_content_viewer_placeholder.jsp?productId=102125&isPDP=true', and special offers. sourceSelector:'' You should not need to rotate the eyepiece more than 1/4 of a turn to do this. entityId: 5662, Orion recommends the 15164 model with 47x11x14â padded case that fits the tube, mount, and tripod. width: 90, .go for bigger aperture. If you have experience setting up a telescope, this process can be done rather quickly from 15-30 minutes. entityId: 4110, }, { defaultImage: '', They typically take a bit longer to learn and need some set-up or adjustments. entityId: 102109, Itâs not the sturdiest mount ever and it does raise some steadiness issues when the tripod is fully extended, but itâs equipped to hold up to 7lbs which the tube barely weighs. MARS: If atmospheric conditions are good, you may be able to see some subtle surface detail on the Red Planet, possibly even the polar ice cap. }, { Just what's so nifty about the Orion SpaceProbe 130ST Equatorial Reflector Telescope? entityType: 'product' layers: 'VID043-Stargazers' The higher the aperture, the brighter the images. }, { defaultImage: '', The R.A. setting circle must be re-calibrated every time you wish to locate a new object. A DC motor drive system can be mounted on all Orion equatorial mounts to provide hands-free tracking. Motor drives are usually equipped with a hand control that allows the telescope's tracking speed to be slightly increased or decreased, which is particularly critical when taking long-exposure astro-images. }, { If the stars appear to “twinkle”, the atmosphere is significantly distorting the incoming light, and views at high magnifications will not appear sharp. Loosen the R.A. lock lever and rotate the telescope until the R.A. value from the star atlas matches the reading on the R.A. setting circle. Our second-gen model ensures seating exactly parallel to the focuser's mechanical axis for consistent and accurate alignment. "Most deep-sky objects are very faint, so it is important that you find an observing site well away from light pollution. If you're looking for a better-quality first telescope or a nicely portable telescope to complement your big Dobsonian, you'll love the Orion SpaceProbe 130ST EQ Reflector Telescope. How do I best view Deep-Sky Objects? It is the portable scope and occupies less space in your room. To find Polaris in the sky, look north and locate the pattern of the Big Dipper. defaultImage: '', To start, loosen the smaller thumbscrews that lock the primary mirror in place a few turns each. See our Learning Center articles: About General Astronomy entityId: 99810, entityId: 99833, entityId: 132740, All optical instruments need time to reach “thermal equilibrium.” The bigger the instrument and the larger the temperature change, the more time is needed. 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. width: 90, This doesn't mean the scope will never be able to reach those higher "theoretical" powers - there will be that rare night where the atmosphere is perfectly still and the scope can be pushed past it's practical limit, but those nights will be few and far between. It is not. More precise polar alignment is required for astrophotography and for use of the manual setting circles. }, { For long exposure DSO photography, there still may be some coma, apparent blurriness, and noticeable drift that is in part due to the mountâs less than perfect polar alignment. For example, the Orion Spaceprobe 130mm EQ Reflector Telescope, which has a focal length of 650mm, used in combination with the supplied 25mm eyepiece, yields a power of: 650 ÷ 25 = 26x.
