Approximately 15% of these species are year-round residents; the rest are migratory. Most of the migrants come into the state during Mthe spring and summer months to nest and raise young, then depart for warmer climates to the south during the winter. Some migrants spend the winter months in Wisconsin and nest farther north. And others spend less than a week or two in Wisconsin each spring and fall to rest and refuel as they travel between far northern Red-bellied woodpecker nesting grounds and southerly win- tering grounds. Still other bird species found in the state are accidental visitors. “Acciden- tals,” as they are called, are consid- ered vagrants. They visit Wisconsin on only rare occasions (i.e., every 5 years or less), primarily due to being blown off their migration course during stormy weather. Acciden- tals often cause great excitement throughout the birding community, Rose-breasted grosbeak as they provide a wonderful oppor- tunity to see a bird not common to the state.

This setup can easily give you a lens equivalent of about 2,300 mm. That’s a very high magnification when you consider the biggest telephoto lenses for regular cameras are usually smaller than 1,000 mm and generally around 400 – 600 mm. Also, digiscoping equipment costs much less than high-quality large telephoto lenses and often weighs much less.

  • Binocular and Spotting Scope Basics
    Binocular and Spotting Scope Basics A good pair of binoculars is a must for most for bird monitoring projects. Certainly, you can observe birds and other wildlife without the aid of binoculars, such as at a feeder, but with them you will see more detail. Binoculars don't have to cost you a lot of money, but should adequately magnify birds for identification. Many 7 x 35 or 8 x 42 power binoculars are affordable and good for bird watching. They should be easy to use and comfortable for you. You can buy binoculars through sporting goods stores, catalogs, and the Internet. How to use binoculars Binoculars are an extension of your eyes. First, use your naked eye to find the birds you are observing. Once you have detected movement and can see the wildlife, use binoculars to see details of a bird’s “field marks.” Everyone’s eyes are different, so before you raise the binoculars, you must calibrate them for your eyes. How to Calibrate Binoculars 1. Binoculars hinge at the center between the two large “barrels,” allowing the eyepieces to fit the width of your eyes (Illustration A). Pivot the hinged barrels so you see a single circle-shaped image, rather than a double-image when looking through them. If the barrels are as close together as they go and you still see two images, you may need to find another pair. The distance between the eyepieces is called the “interpupillary distance.” It is too large if you see two images. The number on the hinge post (angle) will always be the same for your eyes, no matter which binocular you use (A).

  • Scope & Spotting Scope Resolution and Magnification
    Scope & Spotting Scope Resolution and Magnification Eyesight Resolution Limits The normal or median human visual resolution limit is 1 MOA (minute of angle). This is also called normal visual acuity when use by your eye doctor. On the typical Snellen eye chart, the 20/20 line (20 foot line in USA) or 6/6 line (6 meters in the rest of the world) was designed to be readable with a visual resolution or acuity of 1 MOA. The other lines/characters are scaled accordingly. Telescopes were developed as visual aids to overcome this limited visual resolution or acuity. The principal tool for resolution improvement is magnification. It is obvious that magnification increases the apparent size of objects. However and more importantly magnification increases visual resolution. In the following illustration note how even small (doublings – powers of 2) increases in magnification greatly increase our ability to resolve (distinguish) small but important details by both increasing their apparent size and making better use of the available field of view. Fred Bohl, 10 June 2007 Page 1 of 6 Scope & Spotting Scope Resolution and Magnification Scope Resolution Limits Diffraction Limited Optics A long historical record holds that diffraction defines the ultimate resolution limit of telescopes. Generally we can say that any aperture with a finite size will cause diffraction and hence its resolution will be limited. The finite aperture (front lens, main mirror) must cut off a part of the incoming plane wave front. This missing part is disturbing the otherwise perfect interference of the propagating waves in a certain way. The result is a modulation of the wave front called the Point Spread Function (PSF).

  • C5 Spotting Scope XLT 52291
    C5 Spotting Scope - #52291 Instruction Manual A spotting scope is nothing more than a telescope that is designed to look around the Earth. Unlike astronomical telescopes, which produce inverted or reverted images, spotting scopes produce correctly oriented images. Celestron offers several different models, each of which uses the highest quality optics to produce the best possible images. All models have rugged, durable housings to give you a lifetime of pleasure with a minimal amount of maintenance. Your Celestron spotting scope is designed to give you hours of fun and rewarding observations. There are, however, a few things to consider before using your spotting scope that will ensure your safety and protect your equipment. • Never look directly at the Sun with the naked eye or with your spotting scope. Permanent and irreversible eye damage may result. • Never use your spotting scope to project an image of the Sun onto any surface. Internal heat build-up can damage your spotting scope and/or any accessories attached to it. • Never use an eyepiece solar filter or a Herschel wedge. Internal heat build- up inside your spotting scope can cause these devices to crack or break, allowing unfiltered sunlight to pass through to the eye. • Never leave your spotting scope unsupervised, either when children are present or adults who may not be familiar with the correct operating procedures of your spotting scope. • Never point your spotting scope at the Sun unless you have the proper solar filter. We recommend Celestron solar filters only. Don't take chances -- use Celestron filters for safety and performance! When using your spotting scope with the proper solar filter, ALWAYS cover the finderscope.

  • Astrophotography: Tips, Tricks, and Techniques
    Astrophotography: Tips, Tricks, and Techniques Clay S. Turner Sept. 24, 2011 Astrophotography without a Telescope • Use camera on a tripod • Use remote shutter release • Do long exposures with large apertures (“Fast Lenses”) • Include landscape with sky to make image interesting. • Modern low noise DSLRs allow high ISOs to facilitate short exposures. Yellowstone National Park Lowell Observatory Iridium Flares Lowell Observatory Piggyback Astrophotography • Here you attach your camera onto a telescope to use the scope’s tracking. • Camera uses its own lens and not the scope’s optics. • Useful for medium to large areas of the sky. Shot with DSLR and 180 mm lens Three basic ways to image through your telescope. • Prime Focus • Eyepiece Projection • Afocal Photography Prime Focus Imaging • The telescope’s objective is used in place of a “long lens” in photography. Thus the camera, sans lens, is connected where the eyepiece normally goes. • DSLRs are usually used in this mode of Astro-Imaging. • Preferred method of imaging by professional astronomers. Eyepiece Projection • Just like with Prime Focus photography, a camera is used without its lens. But in this case the eyepiece is used to magnify and project the image onto the camera’s sensor (film). • There are special adaptors that will contain the eyepiece and also hold the camera with variable spacing (magnification) permitted. Afocal Photography • In this case the telescope with its eyepiece is focused so an observer while looking into the eyepiece sees the object clearly. Then a camera with a lens is then used to image the object while looking into the eyepiece. Birders often call this technique “digiscoping.” Simple low cost “point and shoot” cameras may be used this way.

We have included many accessories so it will be easy to use this telescope. 1. Included parts we have included several accessories that will make the use of the telescope easier and fun, please take a look at the list of the parts so you can identify them in the future. 1. 1.5x Erecting Lens; 2. 2x magnification Barlow Lens; 3, 4, 5 and 6. Four eyepieces 1.25” (31.75mm); a H20mm, H12.5mm, H6mm and a SR4mm eyepiece; 2. Getting Started. It is very simple to get started. Here is how the telescope works. The telescope aperture should point to the object being observed. The mirror on back of the tube will gather the light coming from the object and reflects it to the secondary mirror that brings it to the eyepiece. Close to the aperture there is the focuser. The focuser moves up and down to get a precise focused image. At the focuser one can use the supplied accessories. Different accessories combinations give different results, such as different image magnifications or correct image for example.

  • A Life-Long Investment...Needs Protecting
    A life-long investment... ...needs protecting. Kowa Protective filter Harsh environments such as sand and salt at the coast, an accidental fall from a tripod or contact with a sharp object can all damage the most sensitive and valuable area of a spotting scope - the objective lens, often causing irreparable damage to the coatings and the actual lens itself. Damage to the front objective lens can drastically reduce the optical performance of your scope and is one of the most costly repairs to rectify, especially if you own a Kowa pure fluorite crystal model. Often the only option is to completely replace the front objective lens at great cost. This type of damage is not covered by the manufacturers warranty meaning a possible expensive and lengthy repair. Impact shock Harsh environment Sharp objects Kowa recommends the use of a protective filter to protect a Kowa spotting scope. All Kowa spotting scopes are conveniently fitted with a filter ring* (a feature often not included in other manufacturers models) allowing the connection of a filter. This low cost accessory will help drastically reduce the risk of objective lens damage, avoid costly repairs and ultimately prolong the life and enjoyment of your spotting scope.
