EXPLORE SCIENTIFIC Truss Dob Counter Weight Set

Universal 60mm viewfinder and guide telescope with a focal length of 250mmExcellent 10x60 viewfinder telescope with removable eyepiece unit and crosshairs with adjustable red illumination. The larger aperture and focal length, provide an even brighter field of view and more accurate tracking due to the higher resolution. The precise helical focuser and the 1.25 inch /31.7mm plug-in connection, as well as the T2 camera connection thread (M42x0.75mm), allow the autoguiding required for long time exposure to obtain a point-shaped star image. It can also be used as a mini travel telescope.High quality 10x60 viewfinder telescope with adjustable crosshair illuminationImage sharpness and viewing characteristics lift this viewfinder well above the level of the usual 10x60 viewfinder scopes. The visible image is bright and crisply sharp. Furthermore, this viewfinder has a very large field of view (FOV) of 6.0 degrees. This makes finding and adjusting objects much easier. The existing scale markings (pitch=0.85 degree) on the crosshair are a good reference for estimating distances, and the open centre markings also make it easier to centre objects precisely. All lens surfaces are protected against weathering by multi-coating and guarantee a bright viewfinder image due to the high light transmission values. The adjustable red LED illumination unit is powered by two LR41 coin batteries. The main lens and the crosshairs can be focused independently of each other, giving you perfect focus for your eyes.Compact tracking unit for autoguidingOne of the main applications for this telescope is the so-called autoguiding. Here the usually larger photo-taking optics are actively corrected by a smaller guiding telescope with a second tracking camera. This means that the mechanical fluctuations in the tracking accuracy, which are present in all astronomical telescope mounts, are measured by the tracking camera and compensated accordingly. This is necessary in order to obtain a point-shaped star image on the astrophotos during long time exposures and to avoid unwanted star trails. For this purpose, the guiding telescope is inserted into the existing viewfinder shoe of the photo-taking optics and aligned parallel. If the existing viewfinder shoe is not compatible, a suitable viewfinder shoe is also included. With the 1.25 inch / 31,7mm plug connection at the rear end or via T2 thread connection (M42x0,75mm), a tracking camera can be mounted afterwards. This is held securely by a brass ring clamp and 3 clamping screws. Please note the required back focus for your tracking camera. The focal plane (backfocus) is approx. 22mm behind the T2 thread. The sensitive focusing on the guiding star is done by a large knurled wheel of the mechanically precise manufactured helical focuser. For easy reproduction of the point of focus, this has a white millimetre scale from 0 to 28mm, which is attached by laser engraving. After the tracking camera has been connected directly or via computer to the telescope mount and the necessary basic settings have been made, the first astrophotos with long time exposure can be taken.Use as mini travel telescopeThis viewfinder and guide telescope can also be used quite simply as a mini travel telescope. With the optional eyepieces, a magnification of 9x to 50x can be achieved. Nearly all eyepieces with a focal length of 5 to 26mm and 1.25 inch/31.7mm plug connection are suitable. Especially recommended are the EXPLORE SCIENTIFIC eyepieces of the 52 degree (Art. 02195xx) and 62 degree (02196xx) LER series. Note: Only straight view use is possible.Metal viewfinder holder and viewfinder shoeThe mount of this viewfinder and guide telescope is completely made of aluminium and is a stable base. The viewfinder mount is suitable for many common types of telescopes, such as EXPLORE SCIENTIFIC, BRESSER MESSIER etc. If the existing viewfinder shoe is not compatible, a matching viewfinder shoe is also included. This can be attached to the telescopic tube by means of four M5 screws. The bore distances of the viewfinder shoe are 31.7mm on the longitudinal and transverse axis. The six large adjustment screws with non-slip knurling make it easy to align the viewfinder, even with clammy fingers. All adjusting and clamping screws have plastic tips that effectively prevent the viewfinder housing and viewfinder mount from being scratched.FEATURESExcellent 10x60 viewfinder and guiding telescopeCan also be used as mini travel telescopePerfect image sharpness and good viewing comfortFMC Multi-coated lens surfacesLens focal length: 250mmMax. possible camera weight: 550gRemovable eyepiece/cross hair unitCamera connection via 1.25 inch / 31.7mm plug connection or T2 threadT2 thread: M42 x 0,75mmPrecise helical focuser for focusing the visible imageFocuser travel range: 28mmClose focus distance: 3 mLaser engraved millimetre scale from 0 to 28mm on the focuserFocal plane (backfocus) is approx. 22mm behind the T2 threadSeparate focusing of the crosshair at the eyepieceVery large field of view FOV of 6.0 degreesWith adjustable red cross-hair iillumination Scale markings crosshair with 0,85 degree graduationPower supply of illumination unit: coin battery type LR41 (2pcs)Brass ring clamp and 3 clamping screws on the 1.25 inch plug connectionWith optional eyepieces magnifications from 9x to 50x can be achievedSuitable are almost all eyepieces with 1.25 inch/31,7mm shaftMounting of the viewfinder telescope is completely made of aluminiumViewfinder mount with 6 large adjustment screws with knurled head for easy gripFinder shoe suitable for EXPLORE SCIENTIFIC, BRESSER MESSIER etc.Additionally a suitable viewfinder shoe is includedBore distances of the viewfinder shoe are 31.7mm on the longitudinal and transverse axisAdjusting and clamping screws have plastic tipsWHAT'S INCLUDED10x60 viewfinder/guiding telescopeEyepiece unit with crosshairCrosshair illumination unit incl. batteriesViewfinder holder with viewfinder shoeInstruction manual

This adaptor connects accessories with the large open diameter of the M48x0,75 thread to the 2,5" Hexafoc. This avoids the vignetting that is caused by adaptors with a smaller diameter - ideal for astrophotographical accessories like off-axis guiders.The adaptor is made from black anodized aluminium.

With teleextenders it is possible to extend the effective focal length of a telescope system, resulting in higher magnification for the observation of the moon, the planets or small Deep-Sky objects with the same eyepieces. So you can use the advantages of eyepieces with longer focal length - such as the bigger eye distance and the more relaxed observing comfort - at high magnifications also.These teleextenders incorporate a telecentric optical design that deliveres a excellent image sharpness over the whole field of view and are premium choices for visual observations and astrophotography. The combination of excellent fully multicoating with superior optical design makes the Focal Extenders superior to classic Barlow lenses.Features: Suitable for visual observations and astrophotographyExtending the effective total focal length of the telescope by a factor of 5xFour lens telecentric design Fully multicoatedFilter thread for color or nebula filters

Massive fork mount with excellent and adjustable mechanics for large binoculars with tripodWhen using giant binoculars, a stable mount and tripod with an appropriate load capacity is absolutely necessary. The new EXPLORE SCIENTIFIC U-mount with field tripod has been specially designed for the EXPLORE SCIENTIFIC BT series of giant binoculars, but also fits most other binoculars from 70 to 120mm lens diameter, which have a 1/4 inch photo thread connection on the underside. With the U-mount there is no shaking or annoying vibrations, the combination is as solid as a piece of iron and provides unlimited observation pleasure in all binocular adjustment positions. Whether you are observing the starry sky or the landscape, the U-mount is a solid base for your giant binocular and allows soft and smooth movements in both axes.The U-mount as a base for giant binoculars and always with you on every excursionAn easily transportable but solid mount is essential when using giant binoculars. A simple photo tripod with ball head or video tilt head is quickly overloaded here. The new EXPLORE SCIENTIFIC U-mount has an excellent mechanism with adjustable friction in both axes, and allows easy adjustment and tracking even when the load is fully utilised. Depending on the adjusted intensity of the friction, the binocular position is kept stable or a soft and smooth movement can be achieved. The large adjustment screws on both axes are smooth and easy to operate even with gloves and clammy fingers. Vibrations are reduced to an absolute minimum by the solid construction of the U-mount. Even at high magnification, there are no shakes and the finest details can be observed. The U-mount and tripod can be separated for easy transport.Mounting the large binoculars on the U-mountThe binoculars can be mounted and removed in a few seconds using the quick-release adapter plate included in the scope of delivery. This is a major advantage, especially for mobile outdoor use. The connection between binoculars and adapter plate is made by two 1/4 inch threaded bolts (standard photo tripod thread), which are variably guided in a slotted hole. A universal use with different binoculars is thus possible. The double screw connection guarantees a very secure fit of the binoculars. The adapter plate itself is also attached to the U-mount with the help of two large clamping screws, which are easy to use even when wearing gloves. Nothing wobbles here and all controls are easy to use.The field tripod provides a secure standNo matter what the surface, the EXPLORE SCIENTIFIC field tripod provides a safe stand. The solid aluminium and stainless steel construction effectively suppresses any kind of vibration. The large 50mm diameter stainless steel tripod legs and the aluminium tripod head plate are an ideal combination and offer maximum stability with a moderate transport weight of only 5.8kg. With applied and retracted tripod legs, the transport dimension is only 80cm long. The included accessory tray additionally gives some tension outwards to the tripod legs and thus to increase the stability. By pulling out the tripod legs, the working height for the binoculars can be individually adjusted within a range of approx. 100 to 140cm.

Ultra Light Dobsonian 254mm GENERATION II - with completely redesigned and improved construction.No telescope type has influenced amateur astronomy as radically as the dobsonian telescope. Before the introduction of this telescope type by John Dobson the vast majority of amateur telescopes were small inadequate refractors on shaky mounts - just good enough to show the polar regions on mars or the rings of Saturn. Bigger telescopes, like the Schmidt-Cassegrain telescopes, were restricted to the relatively small group of amateurs that could afford them.The brilliant combination of simple - but effective - mechanics and the largest aperture available led to a worldwide triumph of this concept. No other telescope type offers you so much light for your money as a good dobson. We have taken the motto "held together by gravity and driven by yoghurt power" and offer a modern version of the classic - designed by amateur astronomers for amateur astronomers. Despite its large aperture the telescope can be transported easily even in small cars and is assembled within minutes without tools. The construction was optimized for maximum rigidity with a minimum of mass. The combination of big altitude wheels and a optimized aluminium-sandwich construction allows for small movements even at high magnifications. The focus position is already positioned to accept our coma-corrector. The ideal workhorse for the deep-sky enthusiast. A telescope with 254mm aperture gathers more than 1300-times more light than the naked eye. Details on planetary surfaces stand out even to unexperienced observers, and countless deep-sky objects show details. Bright globular clusters are resolved down to the core and the view of the lunar terminator will provide a unforgettable experience.Dimensions for mobile use: Rockerbox 395mmx395mmx310mm; Mirrorbox 330mmx330mmx295mm; Trusses approx.700mmEyepiece Height while pointing at zenith approximately 1,15m; 10“ Net total weight: 26,4 kg; 10“ Mirror Box: 14 kg; 10“ Secondary cage +Rockerbox: 9,7kg; 10“ 4 Pairs of trusses: 1,5kg; 10“ Altitude Wheels: 1,2kg ; Focuser thread: M54 x 0.75 mm. Backfocus: 45mm behind the 2" eyepiece holder. 35mm when the 1.25" adapter is mountedSPECIFICATIONS Truss-Dobsonian Telescope in full Aluminium constructionNEW: Slider bearings made from TEFLON und GFK for smooth and precise movementNEW: Improved main mirror cell with completely redesigned mechanicsNEW: Altitude bearings with new designed brake and friction systemNEW: Universal finder slot to enable an easy finder upgradeNEW: Quick-lock fasteners with new springloaded design for comfortable useNEW: Powder-coated yellow altitude wheels to improve durabilityNEW: Laser engraved central mark on main mirrorSCOPE OF DELIVERYTruss Dobsonian TelescopeLED finder with standard finder slotStray light shield for secondary cageMain mirror collimation toolBattery compartment with bag for fansExtension tube for focuserReducer 2"/1.25"Manual
