{"product_id":"vixen-porta-ii-103-ed-refractor","title":"Vixen AXD2 Goto mount with AX103S APO Triplet - 4\"","description":"\u003cstrong\u003eThe AX103S Refractor is a professional grade ED Triplet Apochromat and has been developed for astrophotography for all cameras up to and including full-frame cameras and this one has a Triplet ED lens and at the rear area there is an image field flattening lens.\u003c\/strong\u003e\u003cbr\u003e\u003cbr\u003eThis f8 refractor can also use an optional focal reducer which can further reduce the focal ratio to achieve even faster results in astrophotography. The 60 mm ring on the focuser allows you to attach 2\" eyepieces and a camera adapter. While the AX103S has been specially developed for professional astrophotography purposes, its also a real visual highlight, especially when observing the moon and planets using an eyepiece. This is a telescope that will delight you for a lifetime.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eThe AXD2 mount in detail:\u003c\/strong\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan data-mce-fragment=\"1\"\u003eThe Observatory class AXD2 mount comes with the new 'Starbook Ten' controller and the PFL polar finder, which makes it quick and easy to align the mount via reference stars. \u003c\/span\u003eRobust construction and a lightweight housing with a photographic load capacity of 30 kg. The A7075 Super alloy, which is the strongest aluminum alloy available, is used for the R.A. and DEC axes. \u003cbr\u003e\u003cbr\u003eThe stability of the A7075 superalloy is stronger than titanium, which is known as a lightweight material for high strength. Its density is 38% less than titanium. The use of the A7075 super alloy for the axles makes the AXD mount lightweight yet stable. The rotating parts of the AXD mount have a total of 21 bearings ensuring the smoothest of movement.\u003cbr\u003e\u003cbr\u003e\u003cem\u003eStepper motors:\u003c\/em\u003e\u003cbr\u003eVixen chose more accurate stepper motors for this mount in order to exploit the full performance potential. The disadvantage of stepper motors with large steps has been eliminated by the Micro-Step Motion Control System. The system generates 400 pulses per second at high speed. This creates a very quiet sampling without vibrations while the stepper motors of the AXD mount have more than sufficient torque for higher loads. This is most evident when working at high magnification and astrophotography using CCD astrophotography cameras with small pixel sizes.\u003cbr\u003e\u003cbr\u003e\u003cem\u003eWorm gears:\u003c\/em\u003e\u003cbr\u003eThe sizes of the worm gears have been increased in the latest Atlux version. The AXD mount has 270 teeth in R.A. and 216 teeth in DC. Both axes are 50 mm in diameter. As a result, the mount achieves a high degree of accuracy and running stability.\u003cbr\u003e\u003cbr\u003e\u003cem\u003eLow backlash:\u003c\/em\u003e\u003cbr\u003eThanks to the Vixen Micro-Step Motion Control System, the stepper motors run extremely smoothly from low to high speed. This eliminates the use of reduction gears in the drive system and therefore reduces the play in the gears.\u003cbr\u003e\u003cbr\u003e\u003cem\u003eElegant design:\u003c\/em\u003e\u003cbr\u003eThe flat sides of the mount have been taken from previous generations of the New Atlux range. The white and silver-coloured housing ensures a modern and elegant exterior with high functionality. This AXD mount is the flagship of the Vixen mount series.\u003cbr\u003e\u003cbr\u003e\u003cem\u003ePolar finder telescope:\u003c\/em\u003e\u003cbr\u003eThe AXD mount is equipped with a 6 x 20 polar finder telescope as standard. With the scale built into the polar finder, you can achieve a simple and accurate poler alignment in the northern hemisphere.\u003cbr\u003eFor observation in southern latitudes, the constellation Octans is imaged in the polar viewfinder, which is then set congruently with the real stars.\u003cbr\u003e\u003cbr\u003e\u003cem\u003ePeriodic Errors Correction VPEC:\u003c\/em\u003e\u003cbr\u003eUsually, periodic errors are measured on mounts and corrected by the user. Since the old StarBook did not save this error permanently, the Starbook Ten has addressed this problem. The periodic error of the mount is now measured in the factory and eliminated before delivery. This is called VPEC and it works automatically as soon as you use the mount.\u003cbr\u003eThey achieve an accuracy of +\/- 2.8 arc seconds. You will be able to further increase tracking accuracy by saving your own recorded periodic errors.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eTelescope Spec:\u003c\/strong\u003e\u003cbr\u003e\n\u003cul\u003e\n\u003cli\u003eOptical Design: Triplet Refractor\u003c\/li\u003e\n\u003cli\u003eLens Material: Ohara Japan FPL-53 ED Glass\u003c\/li\u003e\n\u003cli\u003eAperture: 103mm\u003c\/li\u003e\n\u003cli\u003eFocal Length: 890\u003c\/li\u003e\n\u003cli\u003eFocal Ratio: f\/8\u003c\/li\u003e\n\u003cli\u003eResolution: 1.13 arc Seconds\u003c\/li\u003e\n\u003cli\u003eObservatorty class GOTO AXD2 Mount\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eTracking accuracy of +\/- 2.8 arc seconds\u003c\/li\u003e\n\u003cli\u003eMount with 35 kg payload capacity (30kg photographic)\u003c\/li\u003e\n\u003cli\u003eModern STARBOOK TEN control with autoguider input\u003c\/li\u003e\n\u003cli\u003eIlluminated polar viewfinder with direct star adjustment\u003c\/li\u003e\n\u003cli\u003eVery stable vibration-free P85DX observatory column\u003c\/li\u003e\n\u003cli\u003eTotal weight: 64.6 kg\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cem\u003eWhats included:\u003c\/em\u003e\u003cbr\u003e\n\u003col\u003e\n\u003cli\u003eTR102 Tripod\u003c\/li\u003e\n\u003cli\u003eAX103S Apochromat\u003c\/li\u003e\n\u003cli\u003eAXD2 Goto Mount\u003c\/li\u003e\n\u003cli\u003eAXD Half Column\u003c\/li\u003e\n\u003cli\u003e2 counterweights 1.5 and 7.0 kg\u003c\/li\u003e\n\u003cli\u003e7x50 viewfinder telescope\u003c\/li\u003e\n\u003cli\u003eFolding mirror\u003c\/li\u003e\n\u003cli\u003eCarrying handle\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"Vixen","offers":[{"title":"Default Title","offer_id":40917812379843,"sku":"X000113","price":15121.01,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0596\/1924\/6275\/products\/VixenAXD2103EDTripletTelescope_9.jpg?v=1633957541","url":"https:\/\/www.horizonastronomy.ie\/en-at\/products\/vixen-porta-ii-103-ed-refractor","provider":"Horizon Astronomy • Telescope Center","version":"1.0","type":"link"}
