Question: -- Why should I start with a low magnification eyepiece ?
Telescopes FAQ - How to Setup & Use a TelescopeAnswer: -- A low magnification eyepiece has a wider field of view (the amount of sky you see when looking through the eyepiece) than a high magnification eyepieces. The low-magnification eyepiece therefore makes it easier to "capture" an object you are trying to find in your telescope. Your lowest magnification eyepiece will also give you the sharpest image as well as the brightest image .
Related QuestionsQuestion: -- How do I know what the magnification of the eyepiece will be?
Telescopes FAQ - How to Setup & Use a TelescopeAnswer: -- The magnification of any eyepiece used with your telescope will be the focal length of the telescope (consult your manual) divided by the focal length of the eyepiece. A telescope with a focal length of 1200mm will yield a magnification of 60x when you insert a 20mm eyepiece into the focuser. A telescope with a focal length of only 600 mm, however, will yield only 30x when used with the same 20mm eyepiece.
Related QuestionsQuestion: -- How do I use a high magnification eyepiece ?
Telescopes FAQ - How to Setup & Use a TelescopeAnswer: -- Once you have located an object with your low magnification eyepiece, move the telescope so the object is as close to the center of the field of view as possible. Replace the low magnification eyepiece with one of higher magnification. If the object is not visible after you have changed to the high magnification eyepiece , go back to the low magnification eyepiece and start again.
Related QuestionsCan I use my 40 mm Plossl eyepiece for a low magnification eyepiece on my 6" Newtonian?
The Sky Plus - Baltimore based Meade and Celestron Telescope...It is not recommended to use any eyepiece lower than 32mm on telescopes with aperture of smaller than 8". If 40mm is used as a low magnification eyepiece for a 6" telescope, you are risking seeing the secondary mirror. So for a good low magnification view on a 6" Newtonian you should use a 32mm eyepiece.
Related QuestionsWhat magnification will the Erect Image Eyepiece give my telescope?
Draco Productions Frequently Asked QuestionsTo find out what magnification you will get, divide your main objective's focal length (printed on the telescope tube or listed under specs) by the eyepiece focal length--in this case [the EIE], 10.5 mm. So, for a 700 mm focal length refractor such as a typical 60 mm department store telescope, this eyepiece will yield about 67 power (67x) [700 divided by 10.5 = 67].
Related QuestionsQuestion: -- How much magnification should I use?
Telescopes FAQ - How to Setup & Use a TelescopeAnswer: -- Use only enough magnification to provide a useable image. When you reach a point where the image has become so blurred as to lose useful detail, you are using too much magnification! At what point this happens depends on the object you are observing, the seeing conditions (atmospheric clarity and stability) and the size of your telescope (you can get more magnification out of a large telescope before images begin to blur).
Related QuestionsQuestion: -- Which eyepiece should I use to begin observing?
Telescopes FAQ - How to Setup & Use a TelescopeAnswer: -- ALWAYS start observing with the lowest magnification eyepiece available until you become skilled in the use of your telescope. This will be the eyepiece marked with the BIG number (longer focal length ), not one of the smaller numbers. Again, the number you see on the eyepiece is the focal length, not the magnification.
Related QuestionsQuestion: -- Why do things seem to get darker as I increase magnification ?
Telescopes FAQ - How to Setup & Use a TelescopeAnswer: -- A basic law of optics states that as magnification increases, image brightness decreases. In fact, if you increase magnification enough, an object will become too faint to see. This happens sooner in a small telescope than a large telescope .
Related QuestionsQuestion: -- Why do objects in the eyepiece drift out of the field of view after a few moments?
Telescopes FAQ - How to Setup & Use a TelescopeAnswer: -- The telescope is not only magnifying the object you are observing in the sky, it is also magnifying the earth's rotation! The more magnification you use in your telescope, the quicker an object drifts out of the field of view. Manual telescope mounts will require you to continually "recapture" the object by moving your telescope slightly. Motorized mounts move the telescope for you and keep the object in the eyepiece.
Related QuestionsWhat is the magnification?
FAQs for Hawkeye Borescopes and AccessoriesMagnification of a borescope is a measure of how large and object appears when viewed through the borescope as compared to its actual size when viewed from the same location without the borescope. Magnification of a borescope is not constant! The magnification changes as the object distance changes, with larger magnification when the object is nearer the tip of the borescope.
Related QuestionsQuestion 18. What do the inscriptions C or K or WF or H on the eyepiece mean?
Olympus Microscopy Resource Center: Frequently Asked Questio...Answer: C or k identify a compensating eyepiece. Some microscope objectives do not include correction for lateral chromatic aberration. For such objectives (Olympus LB series), the compensating eyepiece completes the correction. WF means widefield; more of the specimen to be seen at a given time. H signifies high eyepoint which means that the user's eyes do not have to be placed very close to the top lens of the eyepiece during observation; a particular boon to eyeglass wearers.

Related QuestionsWhat is the magnification of the otoscope lens?
OtoscopesOur otoscope lens uses between a 3x- 4x magnification. We use the same magnification and focal length as the standard Welch Allyn? otoscope. We actually used their lens as our prototype when developing our otoscope. We figured they have been around for over 100 years and are the leading manufacturer of otoscopes in the world today and would be our best guide to what the optimum magnification and focal length should be.
Related QuestionsIs higher magnification always better?
OtoscopesBigger is not always better when it comes to looking in the ear at the eardrum. The key to finding the proper magnification is to deliver enough magnification that you are able to get a clear picture of the eardrum as a whole yet at the same time magnify it enough to see the details that are important when doing your exam. If you over magnify you can see very clear details of a small area but you are unable to get a clear picture of the entire eardrum.

Related QuestionsQuestion 7: How can I improve getting a target into the center of the eyepiece?
Sky Port: CPC-1100XLTThis is probably the most often asked question for all new CPC owners. The most important thing to know is that your main goal in aligning is make sure that targets are in the field of view. If they're at the exact center, great, but this isn't necessary for an enjoyable night of seeing and in most cases, you'll usually just have the target somewhere in the field of view and that's perfect.
Related QuestionsQuestion: Why is there a systolic BP increase with the control case of low ISO?
FAQ'sQuestion: Why is there bradycardia with hi doses of Epi and propranolol? Doesn't propranolol block all the beta receptors? so there should be only alpha working. Answer: In the presence of propranolol, high dose EPI is acting like NE. The reflex bradycardia (increase in vagus activity is reflex mediated) is due to the rise in BP. Answer: Propranolol has two actions acutely. One is to block the beta1-receptors in the heart to decrease HR and hence decrease CO, tending to decrease BP.
Related QuestionsWhen and why should I use the Eyepiece Cover that came with my camera?
EVOLT E-510 > Frequently Asked QuestionsDuring normal shooting, the photographer's face and the camera's eyecup work together to shade the viewfinder and prevent light from entering the metering system of the camera through the viewfinder. When the camera is on a tripod, light can enter the viewfinder from behind the camera because the photographer may be standing away from the camera.

Related Questionsuk.sci.astronomy FAQThe eyepiece is an essential part of the optical system, so get the best that you can afford. In order, acquire a medium, low and high power eyepiece: A low-power eyepiece is one that gives a magnification of approximately one quarter of the telescope aperture in millimetres. Its focal length in millimetres will be about 4 times the focal ratio of the telescope. A medium-power eyepiece is one that gives a magnification of approximately equal to the telescope aperture in millimetres.Related Questions
What's the eyepiece cover for?
Canon EOS FAQ 2.4 - ViewfinderIt blocks stray light from entering viewfinder when your eye is not up to the eyepiece--like when shooting from a tripod. Since the exposure is determined from light bled from the viewfinder image, light entering the pentaprism could find its way to the exposure sensor. This could cause underexposure. There is nothing terribly special about this piece. If you lose it, just remember to cover the eyepiece with your hand or something else opaque when the exposure reading is being taken.

Related QuestionsWhat are the tradeoffs between spot size, magnification and resolution?
Rad-icon Imaging Corporation - Frequently Asked QuestionsThe combination of focal spot size and magnification determines the theoretical maximum resolution in the x-ray image. The finite spot size of the x-ray source creates a penumbra around the edges of the x-ray shadow, much like the sun casting a shadow of your hand. A larger spot size and a longer object-to-detector distance (ODD) both increase the penumbra and thus the minimum feature size detectable at the image plane.
