That is normal. Finder scopes are only used to make objects easy to locate. The image orientation does not matter for observation.

  • Alt-azimuth: easy to use, moves horizontally and vertically
  • Equatorial: enables precise tracking of objects with only one axis – ideal for high magnifications and astrophotography

  • Moon: from 30 mm
  • Planets: from 100 mm
  • Deep sky: from 150 mm

Warning notes
  • General safety instructions DANGER Risk of suffocation! Improper use of this product can result in suffocation, especially for children. Therefore, carefully observe the following safety instructions. Keep packaging materials (plastic bags, rubber bands, etc.) away from children! There is a risk of suffocation! Keep cords, ribbons, and similar materials away from children! They could accidentally strangle themselves and suffocate! NOTE Risk of material damage! Improper handling can damage the device and/or accessories. Therefore, only use the device according to the following safety instructions. Do not dismantle the device! In the case of a defect, contact your dealer. They will contact the service center and may send the device in for repair.
  • Never look at the sun through an eyepiece/telescope without a certified protection filter. A moon filter can never be used for solar observation. The moon filter is only suitable for moon observation. The solar filter must be mounted in front of the telescope opening, not at the eyepiece. Otherwise, the concentrated light beam through the optics will immediately destroy the filter foil, leading to severe eye damage, including permanent blindness.
  • Never leave the optics unattended. Children and inexperienced adults could point the telescope at the sun without proper precautions and lose their eyesight.
  • Do not expose the device to high temperatures.

QUICK POLAR ALIGNMENT The slip clutches allow you to adjust the telescope to your target object easily – no more searching for adjustment clamps in the dark! An optional polar meter is available, which enables you to locate the celestial pole when it is hidden by trees or buildings. OPTIONAL POLAR FINDER SCOPE The innovative polar finder scope provides a new way to polar align your telescope. Simply align the stars in the crosshair reticle with the same stars in the night sky. Polar alignment is achieved using 3 reference stars. The polar finder is illuminated to facilitate orientation and switches off automatically after 3 minutes to save battery power.

Vixen AXJ GoTo Mount with Star Book Ten Controller
Designed as a complement to the AXD2 equatorial mount, the AXJ mount offers outstanding durability and precision. The AXJ mount can also be used on AXD-TR102 tripods with an adapter. Periodic 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 (total of 12 points per 30 degrees worm gear) and corrected before delivery. This is known as V-PEC and functions automatically as soon as you use the mount. It delivers an accuracy of +/- 4.0 arc seconds. You can increase the tracking accuracy further by saving your own recorded periodic errors. Vixen uses a new Belt-drive system in the AXJ mount. The gear drive was replaced with a toothed belt drive. This gives the mount a quicker reaction time and lower backlash. It also helps to minimize noise. The 6x20 polar finder scope is pre-installed. This allows the user to configure the polar alignment (for both the northern and southern hemispheres). The polar finder scope has a variable illuminated reticle with an automatic power-off function. The brightness can be adjusted in 8 levels so that the user can configure the desired brightness. SETTING ACCURACY OF LESS THAN 3 ARC MINUTES The dark field illumination (red LED) turns on when the push button is pressed. The reticle also lights up in red so that the observer can recognize and align stars in the background of the reticle. The light turns off automatically after a few minutes to save battery power. 2 bearing sets (4 pieces) are used for the shaft of the RA axis. Thanks to the newly developed EQ design, the ZXJ mount has a higher load capacity of 22 kg. As the motors, worm shaft and worm gear are located in the lower part of the mount, fewer counterweights are required than with conventional mounts. The STAR BOOK TEN controller is a modern control system with a high-resolution colour monitor. The STAR BOOK TEN system contains more than 272,000 celestial objects, including 260,000 stars from the SAO catalogue, 109 Messier objects, 7840 NGC objects and 5380 IC objects, as well the soon, moon and planets. Objects can be accessed by name, and information such as images and data can be defined separately. FEATURES +/-4.0 arc seconds with V-PEC V-PEC (Vixen-Permanent Periodic Error Correction) Belt drive system (prevents backlash and minimizes noise) 14 ball bearings Polar alignment (variable fork fix type) Polar finder with reference star alignment STAR BOOK TEN controller with autoguider input Retractable counterweight bar WHAT’S INCLUDED AXJ mount Starbook Ten controller 2 counterweights (3.7 kg and 1.5 kg) GoTo mount with Star Book Ten controller 22 kg load (photographic)

Vixen Polarscope PF-L II for AP & SX Mounts
Vixen’s latest design of polar finder, allows a simple, hassle-free method of polar alignment. The Vixen Polarscope PF-L II for AP & SX mounts has a reticule showing the Pole star (Polaris) and two other stars (Delta UMi and 51 Cep) in their precise positions. By turning the Polarscope you can easily match the reticle with the asterism of these stars in the sky and mechanically adjust your mount’s azimuth and altitude axes to align to the true North Pole. You can then adjust the Polar star to a more precise alignment using the reticule’s year marking (which runs from 2015 to 2040, but in practise can be used much longer after this) . Using this alignment process, with visual reference to the actual stars in the sky, a complicated alignment, using date and time to calculate Polaris offset from the pole is unnecessary. For alignment in the Southern Hemisphere you simply use the Trapezium asterism (Sigma, Chi, Tau and Upsilon Octantis) of the constellation Octans and position the reticule with the trapezium stars aligned to their marked positions. The Polarscope has built-in LED illumination, which is dimmable in many stages, and ensures an automatic shut-off after 2 minutes, saving your battery life. The PFL-II also has an improved edge sharpness, when compared with its predecessor. FEATURES Lighting: LED illumination, with automatic shut-off Power supply: 3v button cell Accuracy: ≤ 3 arc minutes Dimensions: 47 x 55 x 127 mm Weight: 155g Compatibility: Vixen AP, SX, AXJ, AXD Mounts SCOPE OF DELIVERY PF-L II Allen key Battery CR2032 3v

EXPLORE SCIENTIFIC Twilight I telescope mount with tripod
The Twilight I is a light-to-medium-duty alt-azimuth mount and tripod designed to quickly and easily accept small to medium sized refractors, such as the AR102 + AR127s or ED102mm + ED127, and of course, the ED80mm. Lightweight, fast Newtonians will also match up nicely with the Explore Scientific Twilight I mount. As long as your telescope does not exceed 18 pounds and has a Vixen-Style Universal Dovetail bar for mounting the telescope to the mount head, you are good to go. The Twilight I alt-azimuth mount head is made of powder-coated aluminum and there are worm gears on both axes. The adjustable angle head can be tilted forward or back at a 45° angle to allow more clearance for your telescope so you can point it straight up for viewing at the zenith. The Allen hex wrench for doing the mount head adjustment can be safely stored at the integrated magnetic holder.  Slow-motion control cables are attached on the vertical and horizontal axes, and are easy to turn during the night, even with gloves on, due to the over-sized knurled knobs that are attached to the end of each cable. They can be attached to either side of each axis to accommodate right or left-handed users, or different types of telescopes (e.g. refractors vs. Newtonian reflectors) for ease of adjustment. The stainless steel tripod that comes standard with the Twilight I mount has adjustable legs and a wide foot print of 42 inches, which makes the tripod more stable. A spreader bar locks against the inside of the legs to secure the tripod even further, and keep vibrations to a minimum. SCOPE OF DELIVERTwilight I Telescope MountStainless Steel Field tripod
