At its furthest, it barely looks like a red dot, but when it has close approaches near oppositions, then its angular size allows some details to be seen. Just curious to see what the average is A four-inch telescope at 100X or an 8-inch telescope at 200X will provide a memorable view of the "lord of the rings." This is a line drawn near the photograph or drawing which has a label showing the actual length of the bar before being magnified. ... Magnification: 50x/100x; Mount: single-arm, alt-azimuthal; Axes motors: in both axes; SCOPE OF DELIVERY. The higher magnifications can only be used effectively when the atmosphere is calm and 'quiet'. DISCLAIMER: Readers be advised that this blog is just a collection of my personal thoughts, perspective and experiences. Magnification. Even with my Konus 500 telescope at 100X magnification Mars appears no bigger than a small red lentil. I go for the highest power seeing allows. This colorful edition explores the constellations with young readers, guiding them to dozens of galaxies, nebulae, and star clusters. Saturn has 62 moons in … Say you want to see Jupiter, and may be you want it to look at least 1/4 as big as Moon (half the … But ever so often, it gets far enough to be visible when the sun is below the horizon. ( Log Out / Saturn does take high magnification better than other planets. However, the maximum effective magnification comes down to the size of the aperture. Several factors affect the magnification of the telescope then, you can decide what should be the magnification of an ideal telescope for you. Unfortunately the 3X magnification of Garrett P. Servis' opera glasses did not show much detail of Saturn and higher magnification is needed to show the planet's rings. Magnification yielding 1mm exit pupil (give or take) in seeing 6 and above. It appears about as big as Mars appears when Mars at its farthest distance from Earth. The book is a useful resource for agencies supporting the field of astronomy and astrophysics, the Congressional committees with jurisdiction over those agencies, the scientific community, and the public. The more you increase in magnification, the dimmer the planets will appear, hence the larger your telescope, the easier it’ll be to observe! We reserve the right to decline any returns if above guidelines are not followed. It’s going to look the same as 100x magnification because your telescope is gathering a limited amount of light. If you expect to see Saturn rings or constellations I have to disappoint you. Rhea is usually closer to Saturn while Iapetus is further out, and they are about 2.5x and 16x dimmer than Titan respectively. 25-30x – still looks small in the FOV, but you can still start making out large features on the surface depending on the phase. In this article, I’ll explain how you can see Saturn through a telescope yourself, and what to expect. Other times, I start high, and back it off until I get the sharpest view, then stop. 108-115x is about as high as I go on a good night. If you were to increase the magnification up to about 100x, the images would be appreciatively bigger but dimmer still and maybe slightly fuzzy. The moon is different. Even with my Konus 500 telescope at 100X magnification Mars appears no bigger than a small red lentil. You will not likely need beyond 200x magnification. Let's say, for example, you are viewing Saturn at a magnification of 40x - if you are not tracking, Saturn will only stay in the view of your eyepiece for a few seconds. Found inside – Page 89Viewed with low magnifications, Saturn looks much like the flying saucers from a 1950s-era science fiction movie! ... With a medium-sized telescope and magnification of 100X, you can see Saturn's flattened disk, the Cassini Division in ... ( Log Out / During Solar Transits – With a proper Solar Filter, Venus is large enough to be seen as a black dot moving across the Sun even with the naked eye! Sample Of Saturn’s Rings with 50x Magnification Power. Same range here with my 8&10"scopes on good seeing nights. Its maximum magnification may be double that number, but here again -it's not just about magnification. 61 Cygni – 25″ = 30x Luckily here in the tropics the seeing holds good most of the time. Change ), You are commenting using your Twitter account. This 160-page book from Michael E. Bakich, retired Astronomy magazine Senior Editor, introduces readers, from novice to experts, to observing the night sky with accurate, easy-to ready star maps optimized for use with red flashlights. Galaxies are notoriously disappointing through a telescope. Regardless of the scope used, I find Jupiter gets interesting at around 150X; much less than that, the image size is too small to suss out details. Change ). 50-100x – The Galilean Moons appear more spread out, and you can barely start to see the striped pattern of brown and white cloud bands The telescope is attached between the two prongs of a flimsy alt-az mount (the telescope moves … For eclipses, up to 60-80x is the most you should zoom so the entire disc is still visible in your FOV. When looking through a telescope at high magnification … You currently have javascript disabled. This means that if you have an eyepiece that provides 100X magnification through your telescope, that same eyepiece in the Barlow would magnify an object by 200X. Saturn is one of the most popular targets to observe in the Solar System. Found inside – Page 281The Crepe Ring is VERY transparent and sometimes is difficult unless very high magnification is used. ... sharpest (the "Ansae" at each side of the rings) or where the "C-ring" passes directly IN FRONT of the globe of Saturn; indeed, ... I believe that part of this perspective it is due to smaller view (FOV) with higher magnification because you can see less, Saturn leaves your view in a few seconds, forcing you to realign Every couple of … As before, because the smaller scope gathers less light, the image must be a lot smaller to hold the same … Minimum magnification to see Saturn is ringed/Cassini division - posted in Solar System Observing: Ive had a new telescope to try out and with (at last) some decent seeing was surprised how little magnification I needed to see that Saturn is ringed. Jupiter, Saturn, Mars, and Venus are all bright enough that you can push the power fairly high without the image becoming too dim. Venus ~50-100x; always use neutral density filter or polarizer. I know the theoretical maximum useful magnification for my 120mm SW ED is supposed to be ~240x. Btw IMHO the X-Cel LX eyepiece is a great cost / benefit. … 100x ~ 30′ or ½° FOV naked eye). Imagine if you are magnifying the same object at 100x magnification or more! The Celestron AstroMaster 114 EQ motor drive telescope can easily see Saturn’s rings and even several of its moons. At 100x magnification you will be able to see 2mm. GoTo telescope will not … For example, if your telescope has 1000mm in focal length and you’re using a 25mm eyepiece, then you’re using 40x magnification. Most educational-quality microscopes have a 10x (10-power magnification) eyepiece and three objectives of 4x, 10x and 40x to provide magnification … further elaborates on choosing your ideal sky and talks more about seeing conditions – which is essentially how steady the air above is. The closer views of the larger and smaller surface features offer a good variety. In fact it’s roughly 5 times smaller than saturn and almost 8 times smaller, in surface area, than Jupiter. If I only looked at the moon and planets I would observe infrequently. For instance, three eyepieces and a Barlow lens would give you six different magnifications. Found inside – Page 202A 10 mm eyepiece would give this telescope a magnification of 100x . Along with magnification ... he was the first to see the phases of Venus and the rings of Saturn ; he saw nebulae and clusters through a telescope for the first time . So if you have a 4-inch telescope, try 120x to 200x. From people like us! 300x and above – You start feeling like you’re flying above the surface of the moon. Found inside – Page 89To see the GRS, a modest 6-inch (150-mm) telescope magnifying around 100x will do. Because Jupiter rotates once every 9.5 hours, you'll need to know when the GRS faces squarely ... Mars lacks Saturn's exotic appeal but has almost equal. The exit pupil is the diameter of the "light pencil" that emerges from the eyepiece. However, under poor conditions where the air above is very turbulent, then objects will appear like they’re under water even at low magnification. Awkward enough I felt more compelled/ comfortable using the 12mm eyepiece only (100x magnification) more often than the 12mm with the Barlow 2x (200x magnification). I find those 100-degree eyepieces especially fun for the Moon. When used for astronomical viewing, AstroMasters yield breathtaking views of the Moon, Saturn's ring structure, Jupiter's cloud bands and moons, favorite deep sky objects like the Orion Nebula, star clusters, and more. Consequently, if you have a scope with a focal length of 1000 mm and an aperture diameter of 100 mm, then its maximum magnification is around 200x. Finally, as the weather was so cloudy on the day (i.e. The resolving power is calculated by dividing 4.56 by the aperture in inches (or 116 by the aperture in mm). HOW good the object appears will always be a result of many factors such as the size of the scope, the optical quality, the conditions of the sky, the amount of light pollution present, and of course, how good the eyes of the individual observer are. It doesn’t matter if you try to use 300x magnification. Pros: The telescope brings perfect view of the Saturn’s ring, Jupiter and the moon. Found inside – Page 87With a good pair of binoculars or a small telescope , observations of Venus , Mars , Jupiter , and Saturn can be most ... A maximum magnification of 100X ( 100 times ) is adequate for many urban - viewing planetary purposes , although ... I definitely will buy more! Missed the last one in 2012? That varies greatly depending on their distance and phase, but there's rarely much point in going above 100X. Finally, let’s talk now about telescopic binoculars with magnification 40x, 50x and 100x and I will explain when and why you need such powerful binoculars. On the very best nights – perhaps 2 or 3 times per year for many areas – you may be able to push your scope to 200, 300 or 500x magnification. Saturn… If you cannot, even zooming in higher will not fix the problems. One of the biggest drawbacks of small aperture lenses is they don’t allow you to use high magnification eyepieces. Found inside – Page 45Brighter objects, such as the Moon, the planets Venus, Jupiter, and Saturn, and the most prominent constellations, ... When the seeing is bad, astronomers are limited to usable magnifications of around 100x, but in good seeing ... “The Double Double” – 2″ = 375x Moons of Jupiter are slightly visible. They won't seem to merge together into one bright star, but will be closest on Dec 21. If you haven’t seen Saturn through a telescope yet, you won’t believe your eyes! A good rule of thumb for the magnification of viewing planets is the aperture diameter in millimeters multiplied by two or the objective lens in inches multiplied by 50. However, please note that this is an actual optical instrument for those … Start at low magnification and work your way up until you get the best combination … My favorite simple methods are to either … x250 is an achievable, worthwhile magnification on a good number of nights, x300 a lot less so. At 25x, you’ll see Saturn as non-circular, and 50-60x should reveal the rings and the planet’s disk. ( Log Out / A stereo microscope is a good instrument for viewing insects, coins, leaves, or … But, for us to view the image clearly, telescopes require an eyepiece. About magnification: Most educational-quality microscopes have a 10x (10-power magnification) eyepiece and three objectives of 4x, 10x and 40x to provide magnification levels of 40x, 100x and 400x. Jupiter-Usually i use 175x but on one instance i pushed it all the way to 250x and the view just blew my mind OTA; Mount; Steel tripod; 2 pieces 31.7mm (1.25") Kellner eyepieces (K-25mm, K-12,5mm) LED viewfinder; built-in compass; Moon … It does make one new-to-me argument for pushing magnification beyond the point where any more detail is resolvable under the seeing conditions: it may well be easier to see the detail that is there in a larger view, and for some planets, the larger and dimmer view is more comfortable than a smaller too-bright view. Lowest Useful Magnification: You can calculate your telescope lowest magnification by multiplying your aperture (in inches) by 3 or 4 times. At 100x you can see more details on planets like ice caps on mars and the Great Red Spot on Jupiter. You may find info that a 70mm telescope can handle 140x magnification, but that's very theoretical and only for longer refractors (and even there, produces a dim image). As he could see the phases of Venus with his small telescope, so will you! This new edition of Philip's Stargazing with a Telescope has been fully revised and updated to include the latest telescopes and accessories on the market. The book reveals what to expect from a telescope and how to choose the right one. For anything over 300x, though, seeing has to be really really good. In this article I will try to illustrate the views you can expect through different instruments, and perhaps help to decide which one to choose. If you’re looking to see Saturn, the Moon, or any other planets, you’ll want a telescope with a minimum focal length of at least 1,000mm (preferably higher if your aperture is higher too). The 50x magnification power will enlarge the planet enough so that you are able to distinguish the body of the planet and rings that surround it. Found inside – Page 3Saturn will be well placed for observation this month , being on the meridian about 9 P. M. in Gemini . ... Under very good seeing conditions one can use a magnification of about 100X per inch of diameter of objective . SATURN CHANGES ... So … I finally managed to get my new eyepiece (12mm Plossl) and Barlow 2x for a spin. More often times than not, the local conditions in the atmosphere determine how much you can zoom before it gets too blurry and distorted. Found insideSaturn will be well placed for observation this month , being on the meridian about 9 P. M. in Gemini . ... good seeing conditions one can use a magnification of about 100X per inch of diameter of objective . te SATURN CHANGES COLOR . If you can find Uranus, then you can find Neptune as well, but don’t expect them to be spectacular like Jupiter and Saturn. Saturn-200x really shows off the rings The magnification of an astronomical telescope changes with the eyepiece used. , Awkward enough I felt more compelled/ comfortable using the 12mm eyepiece only (100x magnification) more often than the 12mm with the Barlow 2x (200x magnification). If you want to observe the moons of Jupiter and Saturn, you will only need to use 60x - 100x to fit them in the field of view. 0.1 arc-seconds! Now move to at least 100x and take in the view. Smaller and dimmer globulars hence won’t look as good through smaller scopes, and will be more of a notch on your list of objects you’ve seen. Magnification can be calculated using a scale bar. 400x and above – If the seeing conditions are great, then it is possible for you to begin seeing very tiny “swirls” in the lines between the light and dark colored cloud bands. Found inside – Page 208... detectable at powers of 100x by experienced observers, and 200x is often more than enough magnification to reveal smaller features. ... Saturn Saturn, Lord of the Rings, is without doubt the most beautiful object in the heavens. You say you have magnification of 6x. Jupiter Through a Telescope. It is not a rule for me, I seem to prefer it this way. For Jupiter, 56x is about the minimum I use to see 2 cloud bands. Saturn works best at high-ish magnification, bit more than Jupiter but maybe not much more. How to interpret the specs, and public data on objects you want to see? Saturn and Jupiter and the Orion Nebula…Oh, My! All telescopes collect and focus light. 100x – IF the planet is close enough and the air is steady, the apparent size is almost as big as Jupiter, and you can start making out darker albedo features and even an ice cap if you know where to look. Found inside – Page 52BINOCULARS, TELESCOPES, MICROSCOPES, MAGNIFIERS TELESCOPES And binoculars — Saturn, coated 20x telescopes. ... D. C. GIANT Astronomical telescope 100 diameters magnification, with tripod. ... 100X, 200X and 400X $6.00. to have the best minimal magnification. Found inside – Page 84... according to their High - magnification photographs of Echo newsletter . ... This instrument was used at cents apiece , even though it was raining optical aberrations of various telescope 100x on a low , setting moon , and after in ... Sometimes I go for broke if seeing is really excellent and my visual acuity is not in its best form. Remember how we talked about resolving power with aperture? Start at low powers (50 to 100x) and observe Saturn and its neighborhood, looking for up to 9 moons (see the section on 4.5-6" scopes). The objective or front-end of a telescope gathers the light and focuses it through the tube. There are many ways of doing this. With my 70-mm refractor, I usually use 120X. 150x ~ 20′ or 1/3° FOV If you want to observe the moons of Jupiter and Saturn, you will only need to use 60x - 100x to fit them in the field of view. Large and bright globulars that are about 20′ or larger like M4, M5, M13, M22, and C80 (Omega Centauri) are an absolute treat to resolve at medium to high power because they look just like their pictures. Saturn through a 3″ scope at 100x (simulated) This image simulates how Saturn would look through a smaller telescope such as a typical 80mm scope (roughly 3 inch) at about 100x. When someone considers buying a new telescope - the first question will usually be "what can I see through it?" Celestron Astromaster 114EQ Reflector Telescope. The rings consist of billions of particles ranging in size from grains of sand to small mountains.
