When and why should I use the eyepiece shutter?
EVOLT E-330 > 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 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: -- 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 QuestionsWhen do I use shutter priority (TV) mode and why?
Digital Photography FAQShutter priority mode is similar to fully automatic mode, except that you pick the shutter speed. Metering works the same way, but with the shutter speed fixed there is exactly one aperture that will provide the correct exposure in the exposure table. This is what the camera picks for you.

Related QuestionsWhat is the minimum shutter speed I should use to avoid blurry photos due to camera shake?
Digital Photography FAQThis depends upon a number of factors including the focal length, the steadiness of your hands, and vibrations caused by the mechanical parts of your camera, e.g., mirror slap in SLRs. If your lens has a (35 mm equivalent) focal length of X mm, then a good rule of thumb is to shoot at 1/X or faster. Small movements of the camera shift the image more at long focal lengths.
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 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 QuestionsCan I use the Series IV for eyepiece projection photography?
Frequently Asked QuestionsWhile the Series IV was mainly designed for deep sky work, it can effectively be used to focus on the planets and Moon as well. In this case, the Series IV Stiletto bayonet assembly is unscrewed from the Series IV body and used separately. This is necessary since the diagonal and transfer lens assembly attached to the Series IV body forms a small telescope specifically designed to magnify the image on the ronchi grating.
Related QuestionsHow can I minimize shutter lag?
Digital Photography FAQSome cameras have the ability to focus continuously and snap a picture as soon as you press the shutter. This reduces the time spent focusing. Check your manual to see if your camera has this feature. Most cameras will also let you pre-focus by pressing the shutter half way to get a focus lock and then waiting to press it all of the way until you are ready.
Related QuestionsCan I zoom while the shutter is pressed?
Digital Photography FAQThis is a neat trick that can give some strange motion-blur like effects. Unfortunately, it's not possible on most digital cameras. Obviously, you can do if your camera has a manual zoom ring. If you know of a cameras with an unexpected ability to do this, please let me know and I'll mention it here.
Related QuestionsQuestion: -- 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 .

Sharp Vision Scientific Company - Manufacturers of Newtonian...With the Ramsden eyepieces, you can see about 40 degrees wide or about 53 ft. at 1000 yards at 40x power. The wide field eyepieces allow you to see about 55 degrees wide.
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 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 shutter speed?
Adesso --> HomeShutter speed is the amount of time the shutter allows light onto the CCD. The shutter speed is measured in seconds (or fractions of a second for most common pictures). The slower the shutter speed, the more motion is recorded by the camera. A tripod might be needed to use slower shutter speeds without blurring the picture.
Related QuestionsWhat is a shutter lag?
Adesso --> HomeAlmost all consumer-level digital cameras suffer from a rather long (about 1 second) delay before the picture is taken after the shutter button is pressed. This is a big problem when taking shots of fast-moving subjects, for example in sports. On many cameras this delay can be reduced by half-pressing the button before the shot to focus the camera on the subject.
