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 eye injuries! Never look directly at the sun or near the sun through this device. There is a risk of blindness! Children should only use the device under supervision. Keep packaging materials (plastic bags, rubber bands, etc.) away from children! There is a risk of suffocation! FIRE HAZARD! Do not expose the device – especially the lenses – to direct sunlight! The light concentration could cause fires. RISK of material damage! Do not dismantle the device! In case of a defect, please contact your dealer. They will contact the service center and may send the device in for repair. Do not expose the device to temperatures above 60°C!
  • 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.

EXPLORE SCIENTIFIC 82° Ar Eyepiece 24mm (2")
Explore Scientific 82° Series™ extreme wide field eyepieces are optimized to produce high contrast, high resolution, and superior flat field characteristics. The visual effect of these eyepieces with their long eye-relief and their 82° apparent field is truly a full-immersion experience. Your eye is relaxed, allowing you to easily use the "averted vision" technique to study faint details across a huge field-of-view. The 82° Series eyepieces come with a twist-up rubber eye-guard that raise to the desired height for the comfort of the observer, and as experienced astronomers know, eye comfort is critical when trying to observe at the visual limits of the telescope. To keep internal reflections to a minimum, all internal surfaces of the eyepiece barrel are flat black, as well as the edges of the lenses themselves to minimize the scattering of light within the lenses themselves. All 82° Series eyepieces are fully multi-coated and edge-blackened to produce maximum contrast.

EXPLORE SCIENTIFIC 1.25" O-III Nebula Filter 6.5nm
One of the most important obstacles for the exploration of the night sky is the brightening of the night sky by artificial lighting, such as streetlights. The night sky is not really dark in the vicinity of towns or cities, which reduces the visibility of objects beyond the solar system enormously. Depending on the type of celestial object, it is possible to increase the contrast dramatically by blocking the interfering artificial light. The EXPLORE SCIENTIFIC O-III filter uses a characteristic property of the so-called emmission nebulae. Those objects glow in special colors, the so-called emmission lines. Those emmission lines are linked to chemical elements - in this case oxygen. The EXPLORE SCIENTIFIC O-III nebula filter blocks all other colors (and thereby nearly all of the artificial light) and only the two emmission lines of the oxygen can pass the filter. The result is astonishing: suddenly, nebulae are visible in locations that were completely empty without using filters. In suburban skies, for example, the veil nebula NGC 6992 is almost invisible with a 200 mm telescope. By using this filter you can see the nebula and its structures without any difficulties. A must for every visual observer and for astrophotography. The EXPLORE SCIENTIFIC nebula filters come with an individual test certificate - your guarantee for receiving a premium filter.This filter's narrow passband of only 6.5 nm bandwidth highlights the faint emission nebulae or makes them visible even under difficult urban conditions. FEATURESenables the observation of so-called emmission nebulaeblocks almost the entire artificial lightonly the two emmission lines of the oxygen passes the filterband pass width: 6.5 nmnarrow band version for difficult urban conditionsallows more contrast for faint deep sky objectsideal for use near cities, in heavy brightened skiesindividual test certificate included to guarantee you receive a premium filterSCOPE OF DELIVERY1x 1.25" O-III nebula filter
