AXD2 GoTo mount with VMC260L telescope set The AXD2 mount comes with the new STARBOOK TEN controller and the PFL polar viewfinder, which allows you to configure the mount quickly and easily via reference stars.This telescope set has everything that you need for hobby astronomy.It includes a telescope, a mount with automatic tracking and a sturdy tripod. Featuring the STARBOOK TEN control system, the telescope locates celestial objects automatically so that you don't need to search for them manually.Even if you're not an expert, you can still give your friends an exciting tour through the night sky!The AXD2 mount in detail:Robust construction and lightweight housing with 30 kg load capacity (photographic)The A7075 superalloy, the strongest aluminium alloy, is used for the R.A. and DEC axes. The stability of the A7075 superalloy is stronger than titanium, which is known for its strength as a lightweight material. Its thickness is 38% less than titanium. Using the A7075 superalloy for the axes ensures that the AXD mount is both lightweight and stable.21 bearingsThe rotating parts of the AXD mount have a total of 21 bearings. These ensure uniform motion in order to swivel the telescope and track objects.Stepper motorsVixen uses precise stepper motors for the mount in order to ensure optimal performance. The motors are controlled via a micro-step motion control system, which eliminates the disadvantage of stepper motors with large steps. The system generates 400 impulses per second at a high speed. This results in very quiet scanning with no vibrations. The stepper motors on the AXD mount have sufficient torques. This is most significant when working at high magnifications and photographing with a CCD camera with small pixel sizes.Worm gearsThe sizes of the worm gears were increased in the latest Atlux version. The AXD mount has 270 teeth in the R.A. axis and 216 teeth in the DC axis. Both axes are 50 mm in diameter. This ensures that the mount operates with precision and stability.Low backlashThe Vixen micro-step motion control system ensures that the stepper motors run uniformly at low and high speeds. This eliminates the need for reduction gears in the motor and therefore reduces the backlash in the gears.Elegant designThe flat sides of the mount were designed based on previous generations of the New Atlux range. The white and silver housing provides a modern and elegant exterior with high functionality.The AXD is the flagship model in the Vixen mount range.Original motor layoutThe solid R.A. and DEC motor units are arranged in the lower part of the mount. This means that they automatically act as a counterweight. As a result, you require far fewer weights on the counterweight bar. On small devices, no counterweight is required. The counterweight bar can be slid fully into the housing.Polar finder scopeThe AXD mount is equipped with a 6x20 polar finder as standard. The polar finder features an integrated scale, which provides a quick and easy way to polar align the telescope in the northern hemisphere.For observations in southern latitudes, the polar finder features an image of the Octans constellation, which can be aligned with the night sky.VPEC periodic error correctionPeriodic errors on mounts are usually measured and corrected by the user. Unlike the old StarBook controller, the STAR BOOK TEN controller saves these errors permanently. The periodic error of the mount is measured in the factory and corrected before delivery. This is known as VPEC and functions automatically as soon as you use the mount.It delivers an accuracy of +/- 2.8 arc seconds. You can increase the tracking accuracy further by saving your own recorded periodic errors.The VMC 260 telescope in detailThe optics of the VMC260L are significantly better than the traditional Schmidt-Cassegrain telescope. Despite its high 3000 mm focal length, it is just 650 mm long.Featuring a large 260 mm aperture, the telescope collects large amounts of light for serious professional observations and photography of the planets and countless deep-sky objects.Thanks to the dielectric mirrors, the VMV260L guarantees razor-sharp images and maximum brightness. The open lens barrels cool the telescope quicker than conventional closed Cassegrain systems.The telescope can be used with an optional 0.62x focal reducer to reduce the aperture ratio to 1:7.1. This shortens the exposure times and allows you to photograph large objects. The telescope comes with a standard dovetail bar and a carry handle that doubles up as a camera holder for night sky photography.

These eyepieces with their huge apparent field of view not only gave the observer a panoramic visual experience, but they relax the eye so the observer could pay attention to subtle details for extended periods. These ultra-wide angle eyepieces played a critical role in the military for aiming at targets, and their long eye-relief counterparts helped reduce eye injury from recoil.Each 100° Series Argon-Purged Waterproof eyepiece is internally sealed and purged with inert, dry argon gas to prevent internal fogging, to halt the intrusion of fine particulates and fungus. This also maximizes the life of the internal coatings.To make sure, every 100° eyepiece is tested by submerging them down to 1 meter of water for 30 minutes.All 100° Series eyepieces are fully multi-coated and edge-blackened to produce maximum contrast.
