Description
SD81S, SD103S AND SD115S, ARE THE NEW APOCHROMATIC REFRACTOR WITH SUPER ED (= SD) GLASS BY VIXEN!
THE NEWLY DEVELOPED LENS ELEMENT WITH FPL-53 GLASS REDUCES CHROMATIC ERROR (CHROMATIC ABERRATION) TO A JUST NOTICEABLE LEVEL AND ENSURES AN EXTREMELY CLEAR AND SHARP IMAGE.
IN COMBINATION WITH THE NEW OPTIONAL SD REDUCER HD OR SD FLATTENER HD, THESE REFRACTORS ALLOW 44MM IMAGE CIRCLE ILLUMINATION FOR FULL-FRAME SLR CAMERAS. THE INTERNAL DIAPHRAGM HAS ALSO BEEN OPTIMIZED FOR FULL FORMAT.
VIXEN SD APOCHROMATICS ARE IDEAL FOR ASTROPHOTOGRAPHY. BUT THOSE WHO HAVE ALREADY OBSERVED WITH A VIXEN APOCHROMATIC WILL NEVER WANT TO USE ANY OTHER TELESCOPE AGAIN. THE PRACTICAL FOLDING MIRROR ALLOWS YOU TO ATTACH AN EYEPIECE TO A COMFORTABLE VIEWING ANGLE AND A CAMERA AT THE SAME TIME.
ANOTHER ADVANTAGE OF VIXEN SD REFRACTOR IS THEIR RELATIVELY SHORT LENGTH AND THEIR LIGHT WEIGHT.
THE SPHINX PROFESSIONAL 2 (SXP2) MOUNT IS A FURTHER EVOLUTION OF THE CLASSIC SXP WITH A GREATER LOAD CAPACITY AND OPERATING PRECISION, THE LATTER ACHIEVED THANKS TO THE TIMING BELT DRIVE AND LARGE TAPERED ROLLER BEARINGS. WHEN THE SPHINX MOUNT IS IN OPERATION, ITS SOFT BUZZ REMINDS A KITTEN'S PUR!
THE MOUNT HOUSING ALSO HAS THICKER MATERIAL THAN PREVIOUS SX MODELS. THE CENTRAL AXIS OF THE TELESCOPE IS FIRMLY FIXED IN A FORK TO ENSURE HIGH POLAR LOCK STABILITY. THIS IS THE FORK LIKE THE HEAVY DUTY AXJ. THIS ENABLES A FAST BUT ALSO VERY STABLE ADJUSTMENT OF LATITUDE.
A 6X20 POLAR SCOPE IS PRE-INSTALLED TO ALIGN THE MOUNT TO NORTH. IN THIS WAY IT IS POSSIBLE TO CARRY OUT POLAR ALIGNMENT FOR BOTH THE NORTHERN AND SOUTHERN HEMISPHERE. THIS POLAR SCOPE FEATURES A VARIABLE ILLUMINATED RETICLE WITH AUTO POWER OFF FEATURE. THE BRIGHTNESS CAN BE ADJUSTED IN 8 LEVELS. THE POLAR SCOPE HAS A DIRECT ADJUSTMENT THROUGH THREE REFERENCE STARS AND CAN ACHIEVE AN ACCURACY OF 3 ARCMINUTES. IF YOU WANT TO SET UP YOUR MOUNT QUICKLY AND DON'T NEED THE ACCURACY REQUIRED FOR ASTROPHOTOGRAPHY, YOU CAN ALSO USE THE OPTIONAL QPL COMPASS.
THE MOUNTING HEAD IS 35MM IN DIAMETER AND HAS EIGHT THREADED HOLES FOR M8 SCREWS SPACED AT 45 DEGREES. YOU CAN CHOOSE TO CONNECT AN OPTIONAL FLANGE OR AN OPTIONAL DOVETAIL CLAMP. THE THREADED HOLES ALSO ALLOW YOU TO USE AND FIT MOUNTING FLANGES FROM MANUFACTURERS OTHER THAN VIXEN.
THE COUNTERWEIGHT SHAFT HAS THE SAME STANDARD DIAMETER AS ALL SPINX MOUNTS, SO THE SAME COUNTERWEIGHTS CAN BE USED. THE ROD DOES NOT HAVE TO BE UNSCREWED FOR TRANSPORT, BUT CAN SIMPLY BE INSERTED INTO THE HOUSING. BECAUSE THE SPHINX MOUNT IS DESIGNED TO USE THE MOTOR AS A COUNTERWEIGHT, THE SPHINX MOUNTS REQUIRE RELATIVELY FEW COUNTERWEIGHTS.
THE STARBOOK TEN IS MORE THAN A GOTO KEYPAD!
HERE ARE SOME FEATURES OF THIS OUTSTANDING ASTRONOMY COMPUTER
LARGE COLOR LCD MONITOR: THE STARBOOK TEN MONITOR HAS A 5 INCH COLOR TFT LIQUID CRYSTAL DISPLAY WITH WVGA RESOLUTION (800×480 PIXELS, 65,535 COLORS). DURING NIGHT OBSERVATIONS, THE OBSERVER'S EYES ADJUST TO DARKNESS. FOR THIS REASON, THE DISPLAY MAY BE SWITCHED TO A RED BACKLIGHT. RED LIGHT DOES NOT AFFECT THIS DARK ADAPTATION AS LIKE WHITE LIGHT. ALL THE CONTROL AND DIRECTION BUTTONS CAN BE ILLUMINATED RED, SO YOU CAN GET AN OVERVIEW EVEN IN THE DARK. ILLUMINATED BUTTONS CAN BE ENABLED OR DISABLED.
MAP OF THE MOON: A MAP OF THE VISIBLE PORTION OF THE MOON CAN BE VIEWED ON THE SCREEN. ALL THE MOST IMPORTANT POINTS OF INTEREST ON THE SURFACE OF THE MOON ARE HIGHLIGHTED AND CAN BE SELECTED FOR THE GOTO FUNCTION.
FAST CPU: THE STARBOOK TEN HAS A CPU WITH A FREQUENCY OF 324 MHZ, ABOUT 5 TIMES FASTER THAN THE CPU IN THE OLD STARBOOK. THIS MAKES THE STAR MAP LOAD FASTER AND THE SCREEN BECOMES MORE VIVID.
SIMPLE MENU: WITH THE STARBOOK TEN IT IS POSSIBLE TO ACCESS CELESTIAL OBJECTS IN BOTH SPOTSCOPE AND CARTOGRAPHIC MODES. ALSO, IT IS POSSIBLE TO SELECT OBJECTS BY SCROLLING THE STAR MAP IN GRAPH MODE. FREQUENTLY USED MENUS ARE FOUND ON EACH OF THE TEN BUTTONS. THIS ALLOWES QUICK AND EASY ACCESS TO THE MOST IMPORTANT FUNCTIONS DIRECTLY BY PRESSING A BUTTON.
EXTENSIVE DATABASE: STARBOOK TEN CONTAINS OVER 270,000 CELESTIAL OBJECTS, INCLUDING 258,977 SAO STAR CATALOG STARS, 109 MESSIER OBJECTS, 7,840 OBJECTS AND NGC 5386 IC OBJECTS, THE SUN, MOON, AND PLANETS OF OUR SOLAR SYSTEM. IT IS SUFFICIENT TO RECALL THE OBJECTS BY THEIR COMMON NAMES.
P-PEC FUNCTION: IT IS POSSIBLE TO STORE A PERIODIC ERROR CORRECTION TO IMPROVE THE MOUNT TRACKING ACCURACY. THIS IS STORED AND KEPT EVEN IF YOU TURN OFF THE DEVICE AND TURN IT ON AGAIN THE NEXT TIME.
HUNTING FOR SATELLITE AND COMETS: IT IS POSSIBLE TO INPUT THE ORBITAL ELEMENTS OF A SATELLITE OR A COMET DIRECTLY INTO THE STARBOOK THROUGH THE WI-FI CONNECTION OF A PC. IT IS THEREFORE POSSIBLE TO STORE UP TO 10 SATELLITES OR COMETS IN THE STARBOOK
USER DEFINED OBJECTS: THE STARBOOK TEN IS CAPABLE OF STOREING USER DEFINED OBJECTS. THIS WAY YOU CAN SAVE OTHER INTERESTING CELESTIAL OBJECTS THAT YOU WOULD LIKE TO OBSERVE OR PHOTOGRAPH. IT IS POSSIBLE TO INPUT THE POSITION DATA OF UP TO 10 OBJECTS DIRECTLY OR THROUGH THE WI-FI CONNECTION OF A PC.
DIFFERENT TRACKING SPEEDS: YOU CAN CHANGE THE TRACKING SPEED ACCORDING TO THE TYPE OF OBJECT YOU ARE LOOKING AT. THE MOVEMENT OF THE SUN, MOON, PLANETS OR COMETS CAN BE FOLLOWED AT DIFFERENT SPEEDS.
ADVANCED ALIGNMENT ALGORITHM: IT IS POSSIBLE TO OBTAIN A PRECISE ALIGNMENT OF THE MOUNT SIMPLY BY MOVING ON TWO STARS AT LEAST TEN DEGREES APART IN SUCCESSION AND MEMORIZING THEM. YOU CAN PUT LOCATION DATA OF UP TO TWENTY STARS ONTO THE CONTROLLER. IF MORE STARS FOR ALIGNMENT ARE SAVED WITHIN TEN DEGREES THE CONTROLLER WILL REPORT THIS IN THE DIALOG BOX AS THIS WOULD NOT RESULT IN MORE ACCURATE POSITIONING.
STARBOOK TEN HAS LARGE BACKUP MEMORY TO STORE YOUR INFORMATION. THIS WAY YOU CAN TURN OFF THE UNIT AND SAVE THE BATTERIES. WHEN THE MOUNT STARTS AGAIN, THE DATA REMAINS STORED.
ATMOSPHERIC REFRACTION: THIS OPTION ALLOWS YOU TO COMPENSATE OR REDUCE POSITION VARIATION DUE TO ATMOSPHERIC REFRACTION ON CELESTIAL OBJECTS NEAR THE HORIZON.
TRANSVERSE MERIDIAN: THE MOUNT HAS A SAFETY FUNCTION THAT TURNS THE OPTICAL TUBE IN THE OPPOSITE DIRECTION WHEN THE OBJECT REACHED TO THE OBSERVE REACHES THE TOP POSITION, TO PREVENT THE OPTICS FROM HITTING THE MOUNT. HOWEVER, YOU ARE FREE TO SELECT OR DISABLE THIS FUNCTION WHEN YOU WANT TO TAKE PICTURES WITH YOUR EQUIPMENT.
IN ADDITION, THE STARBOOK TEN HAS AN EXPANSION SLOT INTO WHICH AN ADDITIONAL MODULE CAN BE INSERTED. WITH THE OPTIONAL MODULE, IT IS POSSIBLE TO USE AN AUTOGUIDE FOR AUTOMATIC TRACKING OF OBJECTS DURING PHOTOGRAPHY.
SX-HAL130 ALUMINUM STAND: STURDY ALUMINUM PROFILE AND WIDE ATTACHING SURFACE FOR SX AND SXD MOUNTS GUARANTEE USE WITHOUT OSCILLATIONS. ADVANTAGES THAT YOU FEEL IMMEDIATELY IF YOU PRACTICE ASTROPHOTOGRAPHY - NO MORE VIBRATIONS. TO ADAPT TO DIFFERENT HEIGHTS, IT IS HEIGHT ADJUSTABLE FROM 81 TO 130 CM. WITH ITS WEIGHT OF ONLY 5.5KG IT IS PARTICULARLY SUITABLE DURING EXCURSIONS.
