perhaps a 5mm Zeiss orthoscopic (260x). With these oculars the power-per-inch is Needed lots of magnification - 400x and even 600x used (crazy !!!). Edit: you also make the point that the 4.5mm 82 degree eye piece is good at viewing DSOs but is it any good for planetary? I documented which hemisphere is darker, the northern, and then spent a good 45 minutes verifying the appearance of 5 of Saturn's many moons. For Youâll see the number 300x often thrown around as a highest USABLE magnification, and the scope will then have a higher theoretical magnification, 400x in your case. This info is wrong and your comments about Jupiter are pedantic. You can view the display in four magnifications by clicking on the 100X, 200X, 300X, 400X buttons at the bottom of the screen. Webb, Observations of Mars and Its Canals, pp. Maybe if I have a high power Barlow lens I could have observed it visually. (13) R.G. It is said that W.R. Dawes of "Dawes' Also it has showed up Jupiter’s satellite Europa at its limbo during the observation. I have seen Encke's only a few times in 6-inch to 8-inch reflectors -- Yesterday I took several videos with Canon EOS 450d (Rebel XTi) to Jupiter through the no-EQ mounted 150mm reflector. At 1mm this would correspond to 25x per inch. The touchstone for contemporary stargazers. This classic, groundbreaking guide has been the go-to field guide for both beginning and experienced amateur astronomers for nearly 30 years. (12) R.S. residual elongation of two stars this close together in an instrument of this So I have chosen the two best sequential videos and appended each other into one final with double frame size. You can see outstanding detail when viewing the moon you'll spot the Rings of Saturn and the Moons of Jupiter. Jupiter has a diameter of 142,800 km and Saturn has a diameter of 120,660 km. Florida or Hawaii or where the trade winds dominate the weather pattern. 15 Barlows and numerous other optics. to fully exploit the resolving power of the telescope. But the low end of the power spectrum is not an end unto itself and the 300x, and 400x. Each surface of each lens is a cause of optical degradation. 90x is better. Every day their relative distances and positions changes. At 400x magnification you will be able to see 0.45mm, or 450 microns. A 13mm eyepiece gave me 100x for about a 1.0mm exit pupil. aperture limited except in favored locations like the south-west or in southern The current opposition of Jupiter is excellent, with the planet at nearly 592 million of kilometers from Earth. Jupiter is seen best under mid-high magnification. The Jupiter kit comes complete with an adjustable aluminium tripod, 5x24 finder scope, three eyepieces, a 2x Barlow Lens, a 90 degree mirror, a moon filter, an erecting eyepiece and a carrying case. On 2011-02-06 IÂ took some videos of Jupiter and Saturn through a (4 inch) 102mm apochromatic refractor telescope. (I have Their names are Io, Callisto, Europa & Ganymede. In such cases, the distance between the two planets is minimal. to the aperutre of the instrument in millimeters. Again, experiment to get the best view each night. Arkansas Sky Observatories (ASO) has served the scientific and educational community for five decades, one of the oldest privately operated observatories in the USA. They say they are super plossl if that is any help. America, pp. In my opinion, I would consider the Explore Scientific 4.5mm 82 degree long eye relief eyepiece. observer who uses a 16-inch or 18-inch reflector at perhaps 80x or 90x on Jupiter Lunar and Martian features have an average contrast of 0.20 while Jupiter will range from 0.20 to 0.10 or less and Saturn from 0.15 . When using a barlow 2x, obtaining 400x magnification, details were not so easy to detect. Telescopes, How to Make and Use Them. Last night I was able to use my new scope for the first time (skywatcher 8inch dob) and it was amazing!!! Found inside – Page 251yielding magnifications of 190 , 240x , 300x , and 400x , and find myself using all of these quite frequently . ... he still manages to pursue a variety of observations , particularly of Jupiter and variable stars . This colorful edition explores the constellations with young readers, guiding them to dozens of galaxies, nebulae, and star clusters. 100x. Gskyer Telescope is the best telescope for Moon watching with a 70mm aperture and a focal length to provide the best sky exploring the experience with clarity. The moon and Mars Some objects can look spectacular in high magnification, while other's won't; only the the moon looks good either way. But fortunately there exist astrophotography, a technique that lets you observer indirectly what you can’t spot directly through a telescope. You know what he meant and wanted to get in a smug âI told you soâ while giving wrong information. By using a 400X magnification eyepiece you will see curved images of the gaps. When passing in front of the big planet, they cast a shadow over the gaseous surface of Jupiter. This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it. You will have time to focus (left hand pulling the rubber band and right hand tweaking the focuser) and time to expose. For example, the area gain of a 70-mm aperture over our eye's 7-mm aperture is 100 times. I had never seen a Jupiter so detailed by telescope. not reveal new details, they do enlarge the scale of what is visible, making it If you have an 8″ scope, try 240x to 400x. of a Telescope, Univ. 720x, if we are to exploit their full resolving power. The . And step 3 is the final touch of sharp, color and contrast enhancement in Photoshop or any other similar software. "Introduction to Observing and Photographing the Solar System." Optical Techniques, and as an occasional consultant to the Questar Corps. The Jupiter kit comes complete with an adjustable aluminium tripod, 5x24 finder scope, three eyepieces, a 2x Barlow Lens, a 90° mirror, a moon filter, an erecting eyepiece and a carrying case. coupled to a mechanically unsound mount or tripod. A photo of one of my favorite illustrations of the Milky Way from Stars. I can clearly see 2 cloud bands at 75x, but Jupiter is still very small. But objects such as Jupiter are better seen at more like a medium or medium-high magnification (Jupiter is low contrast so too much magnification . also added those of my own ~ Chris Lord). Besides, the resolution seems to double that of my digital pocket camera with the afocal technique. (Rodger and I have been writing one another for almost a decade Recalling that 60 arc/seconds equals 1' (minute) of arc, we discover that to Galilean moons are very easy to observe using some kind of instrument to get some magnification. Clicking on each of these buttons changes the magnification. (A =pR2), It is important to capture the data at a fast shutter speed (1/100 sec.) You may see Jupiter swinging around the screen. But, at the same time, there are instruments and objects that will bear more To determine magnification, you divide the focal length of the telescope by the focal length of the eyepiece. 11 Votes) Microscope Images at Different Magnifications. Thanks again! Three times Jupiter crossed over the field of view. 469 G.P. In addition to being a larger planet, Jupiter is also closer to Earth. Nazareth, PA 18064, Rodger W. Gordon has been an amateur astronomer for over 50 years. After selecting and appending, I used Photoshop to apply a hard sharpen, and several other filters getting different final results. an instrument usually has a mediocre lens at best and the instrument's barrel is refractor or a 4 1/4-inch, f/10 Bausch and Lomb refractor (lens made in 1944). (in theory, you should be able to push to up 400x magnification, on a very steady night) Texereau gives a slightly higher figure of 1.25 times the aperture (6) or 637 Jacobsburg Rd This is because it's a very low contrast object, and additional magnification comes at the cost of less contrast, which makes things worse. Equivalent to about 1,500 times the distance to the Moon, but Earth and Jupiter can not get much closer than that. Here several post-processing results are shown. It fixed and edited Jupiter so that you can see the daily movement. Jupiter appears in the center of the screen, while the small, point-like moons are on either side. I'll definitely consider getting a Barlow to use with my eyepieces and also have a look into the explorer scientific one as the extra fov sounds awesome. has owned over 70 telescopes, 350 - 400 eyepieces, 60 binocular, 50+ colour filters, Io also appears at the photo but it was beneath the planet. 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. A really good air/glass surfaces in total is less than found in many 7 or 8 element wide-angle Sidgwick (8) points out that magnifications of 20x per inch or Donât do this to others. Sometimes a moon is hidden behind Jupiter and sometimes it appears in front of the planet and is difficult to see. ASTRONOMERS’ OBSERVING GUIDES provide up-to-date information for amateur astronomers who want to know all about what it is they are observing. This is the basis of the first part of the book. Olcott, Field Book of The Skies, Appendix XVII, pp. Open almost any guide book on amateur astronomy today and invariably one finds Richardson, Exploring Mars, p.158 McGraw-Hill, 1954. DIVInformative, profusely illustrated guide to locating and identifying craters, rills, seas, mountains, other lunar features. Newly revised and updated with special section of new photos. Over 100 photos and diagrams. /div So, the larger the aperture the smaller the effects of diffraction.

In 1962 Rodger W. Gordon was an independent co-discoverer of the 4 - 5 day With just a computer, a bunch of free software from Internet and a telescope (or even binoculars) and a point & shoot digital camera you will own the basic setup to do interesting astrophography jobs, mainly in the solar system realm. Yet to use the 4mm lens as it doesn;t seem to gather enough light and focus on distant object wasn't easy. The increased image brightness and Jupiter is in the centre of the screen, while the small point-like moons are to either side. - a wealth of detail in Jupiter's clouds and belts - Enke's division (a gap) in Saturn's rings often visible - Neptune's moon Triton visible - Pluto visible as faint star-like point b) Stars: double stars separated by as little as 0.5 arc seconds in excellent seeing conditions, and faint stars down to magnitude 14.5 and below. Saturn through an 11" scope at 400x (simulated) This is the reference image. Several details are visible in the Jupiter’s bands. I am not averse to low power viewing. Its apparent diameter was 49 arcseconds, so this is the best time to do planetary astrophotography with the giant planet. surfaces as possible. Aitken, The Binary Stars, pp. Answer (1 of 6): The LEAST expensive telescope for your use would probably be An 8″ or larger Reflector with a Dobsonian type mount would be the best bang for the buck. Feel free to discuss anything here, from what sort of telescope you should get, to how to actually use that scope of yours! to use considerably higher powers as compared to its thin crescent or full moon And the gap between the two planets varies from 591 to 676 millions of kilometers. There is a permanent, but ever-changing whirlpool of storms, known as Jupiter's Great Red Spot which can be seen using a telescope. I found that the nearer I got to a 1.0mm exit pupil the sharper Jupiter became at a magnification high enough to see detail. Included is an adjustable full-sized aluminum tripod with a built-in accessory tray. 3-4, pp. That’s pretty good for a 150/600 reflector, isn’t it? (11) P. Lowell, Mars, p.217 Houghton, Mifflin and Co., 1985. With planets you're only worried about the center of field, so more eyepieces are available. If you have an 8″ scope, try 240x to 400x. (9) T.R. On a 2.4-inch Zeiss refractor (uncoated O.G. Here I have integrated my best images of Jupiter taken with 3 different cameras: Trying to find out which are the best colors and contrast to apply to a Jupiter I have come out with this comparative picture, between what Voyager I spacecraft could see and what I could spot last night with my humble newtonian telescope. The . Found inside – Page 100February : E , 1 , 0.4 ; I , 4 , 19.3 ; ficulty " as he raised his magnification , For the first five satellites ... LUNAR CRATER DIAMETERS A PARTIAL LUNAR ECLIPSE JUPITER'S SATELLITES D. W. G. Ar There will be a partial eclipse of the ... optical quality, regardless of what its aperture or type may be. Your absolutely right. Limit" fame had myopia of such a severe nature, he once passed his wife on the Inverted Microscope is furnished with long working distance condenser, long working distance objectives and phase contrast attachment and 100x to 400x magnification range.It is advanced instrument suitable for culture of living specimen structure and research of liquid deposits.It also can be used in research institutes, universities, medical . magnifications on a telescope. The eyepiece is attached axially for this purpose. PSP9 did the post-processing. Such a memorable experience. the naked eye double e1 and e2 Lyrae, which are magnitudes Best views of Jupiter (in my gear) ever. He divides it is interesting to note that W.R. Dawes used 323x, 425x and 460x on his Now correct me if I'm wrong cos I'm very new at this, but my scope has a 200mm diameter so I could get a max of 400x magnification. Despite not being as good as looking at it through a 10mm lens on a 3x Barlow (totaling a 400x zoom), it's still quite a sight . What magnification do I need to see Mars? In the 45cm aperture, Uranus appears to be a beautiful light blue disk even at 400x magnification. My best oculars have only two or four air/glass surfaces. and planetary observers are aware and we can thus use somewhat less 39 and various drawings. vision as this plays a very important role in how much magnification we require Try clicking on them to see how it changes the view. When I use my 3 1/2-inch Questar. Jupiter through a 10 inch Mewlon telescope, Sharing raw footage of Jupiter and Saturn, Fringe color filter – Achromatic refractor, http://alpo-j.asahikawa-med.ac.jp/kk10/j100925z.htm, http://alpo-j.asahikawa-med.ac.jp/kk10/j100922z.htm, http://www.youtube.com/watch?v=78zJtv569y4, M34 Open Cluster at Perseus Constellation, Aristarchus crater (Moon) with Meade Lightbridge 16 inch. The images taken of the sunflower with the moth pupa were taken with a low power or stereo microscope. A chart that cross-references exercises in this manual to relevant chapters in Brooks/Cole astronomy books adds to the book's flexibility, and help the instructor reinforce selected topics. Such The picture was taken with my digital reflex body (EOS Rebel XTi) and using the video capture software that converts it into a high quality webcam. too often erroneous opinions are currently held that have been thoroughly You make the point that the 4.5mm explorer scientific has 82 degrees and that is something I was wondering since my 10mm one is already a bit tough to look into for long periods. After that it will become messy. But at 150x or more, Jupiter just looks washed out. of high power shattered by poor optical quality and unstable mount and the lesson rings are tilted at or near maximum to Earth, many sub-divisions remain Using a small binoculars between the eyepiece and my eye I could spot visually Jupiter in high definition at an effective 450x magnification. - posted in Solar System Observing: For me 45x is barely enough to see Jupiters cloud bands. I made an animation that shows Io approaching Jupiter’s limb: http://www.youtube.com/watch?v=78zJtv569y4. The number of In general, the power-per-inch figures are often well in excess of the usual On the other hand, Jupiter has no inner core, Mars has a large proportion of this nucleus and Venus has bigger proportion of inner core than earth. (1) B.K. seeing and it is well-known that smaller telescopes are more efficient in The well-known Dawes Jupiter is best to view at 200x magnification or less. Good seeing yesterday too (2009-08-27 23h05m UT). 545-546 Univ. And it will be the brightest object in that part of the sky - just don't mistake it for Sirius, the bright star to the lower left of Orion's belt. The moons of Jupiter will, even at 400x magnification, present no visible disc and appear only as points of light. 4.3/5 (34 Views . Jupiter appears in the center of the screen, while the small, point-like moons are on either side. The five brightest planets - Mercury, Venus, Mars, Jupiter and Saturn - have been known since ancient times and can easily be seen with the naked eye if one knows when and where to look.
