You see up to 40% more detail when you use both eyes to observe, compared with single eye viewing. Your brain interprets the two images to give an illusion of depth, an almost three-dimensional quality to the view, even though the image is not true stereo. In addition, it is simply more comfortable to use two eyes to view, rather than squinting through a single eyepiece.\u003c\/p\u003e\n\u003cp\u003eThis straight-through binocular viewer uses paired 1.25\" eyepieces (not supplied). It is designed to fit directly into the focuser of reflectors, and into the star diagonal of refractors and catadioptric scopes for more comfortable viewing at the zenith. Because of its long 5.1\" internal light path, it includes a 2x image amplifier. This is used as a transfer lens to bring the image back to the eyepieces when used with reflectors and refractors (which usually do not have enough back focus to handle the long light path). This results in a 2x magnification boost, so 32mm eyepieces in the BinoVue have the same magnification as 16mm eyepieces used normally. Keep this 2x magnification in mind when choosing eyepieces to use with the BinoVue. Catadioptric scopes (Schmidt-Cassegrains and Maksutov-Cassegrains) usually have enough available back focus, and the image amplifier should be removed with these scopes. However, the BinoVue, even with the image amplifier removed, still provides about a 25% increase in the effective focal length of a catadioptric scope. Some ghosting may be visible when bright objects are just outside the field in this configuration, but careful eye positioning can minimize this effect.\u003c\/p\u003e\n\u003cp\u003eEyepieces should be of identical make and focal length for best results. Tightening the knurled rings around the eyepiece holders clamps internal compression rings onto the eyepieces to hold them in place. There is no separate diopter adjustment to match the eyepieces to your individual eyesight, so any eyepiece adjustments need to be made by loosening the compression ring on one eyepiece, sliding the eyepiece in or out until its focus matches that of the other eyepiece, and retightening the compression ring.\u003c\/p\u003e\n\u003cp\u003eThe BinoVue has a 1.25\" nosepiece. If used in a 2\" diagonal with an optional 2\" to 1.25\" reducer, make sure that the Binovue does not extend far enough into the diagonal to touch the mirror.\u003c\/p\u003e\n\u003cp\u003eThe BinoVue is covered by TeleVue's 5-year warranty. However, the warranty does not cover abuse. Rough treatment or dropping the BinoVue may cause its prisms to get out of collimation, giving double images. According to the TeleVue instruction sheet for the BinoVue, \"Disturbance of collimation is usually evidence of abuse. It is warranted at the discretion of TeleVue.

Its compact size and light weight makes it ideal for spur of the moment backyard observing or for traveling.\u003c\/p\u003e\n\u003cp\u003eThe Tele-Pod consists of a 2-section black anodized aluminum tripod with a manually-adjusted rising center post and a separate yoke \u0026amp; cradle type mount head. The top section of the tripod legs are foam covered for increased vibration damping and more comfortable carrying in cold weather. Each tripod leg has a rubber-tipped foot for use on wooden decks and other hard surfaces. The rubber foot retracts to reveal a metal ground spike for a more firm footing on grass or dirt. The tripod's adjustable height reversible center column has a 1\/4\"-20 stud on one end and a removable 3\/8\"-16 stud on the other, allowing use with standard photo tripod pan heads, as well as with the Tele-Pod mount head. By varying the length of the telescoping two-section legs and the height of the rising center post, the telescope height can be set anywhere from 28\" to 62\".\u003c\/p\u003e\n\u003cp\u003eTeleVue scopes attach to the Tele-Pod head by means of two supplied studs that thread into the base of the telescope mounting ring.

You use its supplied camera tripod-type pan handle to move your scope from object to object. There are no slow motion controls, but the panning motion of the mount is so smooth that most observers will not need them. The yoke \u0026amp; cradle type mount head balances your TeleVue scope at its center of gravity, so that the scope will not swing unexpectedly when you let go of the pan handle (which can be set up for either right hand or left hand use). The altitude bearings are brass, while the azimuth bearing is aluminum and Teflon. Both altitude and azimuth motions have tension adjustments to set the friction to accommodate differing scope weights.\u003c\/p\u003e\n\u003cp\u003eBecause the Tele-Pod head has two mounting holes in the underside of its built-in azimuth bearing, it can be removed from the tripod and used on any camera tripod legs having either a 1\/4\"-20 or 3\/8\"-16 screw. The Tele-Pod head therefore can also be bought separately (without tripod) if you already have a set of photo tripod legs available. In addition, the Tele-Pod head is pre-drilled so it can be fitted with an optional TeleVue Sky Tour computer-aiming system for easier location of deep sky objects. Because there is no accessory tray available for the Tele-Pod tripod, a useful accessory would be the Eyepiece Caddy Set that attaches to the Tele-Pod head and holds up to five eyepieces.\u003c\/p\u003e\n\u003cp\u003eThe Tele-Pod can also be used with other brands of small refractors. However, the internal width between the vertical sides of the Tele-Pod yoke measures only 5.25\", so the maximum width of the mounting rings of another brand of telescope must be smaller than this measurement. In addition, the buyer should keep in mind that the fore-and-aft mounting platform dimension of the yoke is limited and would require a user-supplied adapter plate to install dual mounting rings on the single 1\/4\"-20 thread hole available in the Tele-Pod yoke.\u003c\/p\u003e\n\u003ch2\u003eTech Details: \u003c\/h2\u003e\n\u003ctable id=\"product-attribute-specs-table\" class=\"table\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eWeight\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e7.5 lbs.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWarranty\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e5 years\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"TeleVue","offers":[{"title":"Default Title","offer_id":40221640687689,"sku":"TVTP","price":606.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0573\/7974\/9961\/files\/TPM_3015_TelePod_AdvancedMount_v2.jpg?v=1723750533"},{"product_id":"sky-tour-computer-only-needs-encoders","title":"TeleVue Sky Tour Computer Only (Needs Encoders)","description":"\u003cp\u003e\u003cmeta charset=\"utf-8\"\u003e\u003cspan style=\"color: rgb(255, 42, 0);\"\u003e\u003cstrong\u003eThis product has been discontinued and is no longer for sale.  This is here for informational purposes only.\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eThis Sky Tour object locator computer adds \"brains\" to your TeleVue Gibraltar, Panoramic, or Tele-Pod altazimuth mount.

Instead, TeleVue has wisely chosen to include only those objects that can be seen, and seen in detail, by beginners and experienced astronomers alike.\u003c\/p\u003e\n\u003cp\u003eThe 2000+ database objects are organized into six catalogs: NGC (New General Catalog), M (Messier), IC (lndex Catalog), ST (Star), NS (Non-Standard), and PL (Planets). For quick reference, an additional FAV (Favorites) catalog is available to store 99 of your favorite objects.\u003c\/p\u003e\n\u003cp\u003eThe Sky Tour instructions are easy to follow and include step-by-step diagrams. A simple phone plug connects the computer to the TeleVue mount. Turn Sky Tour on, align the marks on the mount head, sight two known stars from a choice of 31 in the computer's memory and Sky Tour is ready to lead you on your evening's journey around the heavens. There's no need to enter your latitude, longitude, date, or time to find your way around the sky outside the solar system. Once you've gained a little familiarity with the stars, the alignment will take you only slightly longer than it did to read this paragraph! Within the solar system, if you want the Sky Tour to lead you to the planets, simply input the current date and time and choose your planetary target.\u003c\/p\u003e\n\u003cp\u003eSky Tour's functions are organized into nine \"modes.\" They are: Star Fix, RA DEC, Catalog, Guide, Align, Identify, Timer, Install, and Encoder. Once Sky Tour is aligned, you enter the Catalog mode and choose an object to view. \u003cem\u003eCatalog \u003c\/em\u003emode displays the location, brightness, size, and other information about the object chosen. It also includes the chart number that contains the object in the popular Sky Atlas 2000.0 star atlas. Then switch to \u003cem\u003eGuide \u003c\/em\u003emode and the Sky Tour shows you the direction to move the scope in order to center the selected object. As you move in the direction(s) shown Sky Tour visibly counts down the distance to go to reach the object. When Sky Tour shows you're at zero distance to go, you're centered on the object. Finding over 2000 objects is as simple as that.\u003c\/p\u003e\n\u003cp\u003eSky Tour also gives you highly accurate digital setting circle readouts by converting Alt\/Az positioning into Right Ascension and Declination. The \u003cem\u003eRA DEC \u003c\/em\u003emode lets you hunt for any object in the sky just by looking up its RA and DEC position on a star chart and using the setting circle function to guide you to that position.\u003c\/p\u003e\n\u003cp\u003eAs you scan the sky, the Sky Tour's \u003cem\u003eIdentify \u003c\/em\u003emode will point you to the nearest object of your choosing. For example, say you wanted to know if there was a galaxy near where your scope was pointing. Enter the \u003cem\u003eIdentify \u003c\/em\u003emode, choose \"Find GX\" from the nine object types. If there is a galaxy nearby, Sky Tour will identify it and guide the way to it. It's a wonderful way to learn about unfamiliar regions of the sky. The \u003cem\u003eIdentify \u003c\/em\u003emode is fun for explorers who like to scan the sky just to see what they can find. When you think you've found something, just ask Sky Tour's \u003cem\u003eIdentify \u003c\/em\u003emode to \"Find Any.\" If the object is in the Sky Tour's database, it will tell you what it is and give the pertinent details about the object.\u003c\/p\u003e\n\u003cp\u003eThe Sky Tour has a 10-character red LED display that can be dimmed to any of five brightness levels. It has a display resolution of 1 minute in right ascension, and 0.1° in declination. The optional encoder kits use 2160 step, 0.167-degree\/step (10-arcminute\/step) encoders. You can move the scope at a very fast 160 degree per second rate without losing the Sky Tour's lock on the sky.\u003c\/p\u003e\n\u003cp\u003eThe Sky Tour has six display modes. First is STAR FIX, which is the alignment mode using a convenient built-in 31 star list of the brightest stars visible. Next is RA DEC, which shows the current right ascension and declination to which your scope is pointed. Next is CATALOG, which is the complete database of celestial objects in the computer's memory. Next is GUIDE, which shows the direction and distance to the chosen object. Next is ALIGN, which uses the full database to fine-tune the alignment of the Sky Tour on the sky. Last is IDENTIFY, which identifies the object you are aimed at, by type.\u003c\/p\u003e\n\u003cp\u003eThe Tom Lorenzin 2000+ catalog database includes: the Messier objects; selected NGC objects; selected IC objects; selected Non-Standard objects; selected Stars, including colored, double, and multiple stars; 31 alignment stars; 8 Planets; and a customizable FAVorites database that can hold 99 objects. All are listed using Epoch 2000 coordinates.\u003c\/p\u003e\n\u003cp\u003eThe Sky tour measures a compact 2.8\" x 4.6\" x 1.1\" in size. It weighs a mere six ounces, including the 9 volt battery that powers it.\u003c\/p\u003e\n\u003ch2\u003eTech Details: \u003c\/h2\u003e\n\u003ctable class=\"table\" id=\"product-attribute-specs-table\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eWeight\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e9 oz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWarranty\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e5 years\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"TeleVue","offers":[{"title":"Default Title","offer_id":40221640753225,"sku":"TVST","price":315.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0573\/7974\/9961\/products\/4232_1.jpg?v=1662966921"},{"product_id":"flip-mirror-for-older-starbeam-finders","title":"TeleVue Flip Mirror for Older Starbeam Finders","description":"\u003cp\u003eThis light-weight pivoting first surface mirror allows a Starbeam to be used as a straight-through finder, a right angle finder for observing at the zenith, or at any angle in between.

The Starbeam is normally used as a straight-through finder, similar to the heads-up display in a military aircraft cockpit. However, the Starbeam has a pivoting light-weight first surface flip mirror that also allows the Starbeam to be used as a straight-through finder, a right angle finder for observing at the zenith, and at any angle in between.

The eyeguard can be raised in small and repeatable increments to position the eye of the non-eyeglass wearer the precise distance from the eyepiece to see the full field of view with maximum suppression of ambient stray light.
