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 Filter Set 1 Moon & Planets from 50mm (2'')
Filter Set 1 is recommended for Moon & Planets from 50mm (2'') Aperture Set 1 includes the following filters: Explore Scientific Filter 1.25" Light Yellow No.8 - 0310268 Watching the Moon surface through the filter, the contrasts will enormously increase. Same with planet Mars. On the huge planet Jupiter, when using the filter, you can even see the contrasts between the cloud-bands and a lot more details. Starting with a telescope diameter of 8“ and a clear sight, you even get to see various details of Saturn. Explore Scientific Filter 1.25" Orange No.21 - 0310273 This one really supports the detection of the dark areas on the planet Mars. The details of the clouds of Saturn and Jupiter are also so much more visible through the Filter. Explore Scientific Filter 1.25" Blue No.80A - 0310264 The color of light blue really supports watching the high clouds on Mars. The contrast increases. The dark red structures will be shown even darker, so this is the perfect filter for watching the big red Flecks on the gas planet Jupiter. The rings of Saturn will be accentuated, the structures of the Venus Atmosphere will be even finer. EXPLORE SCIENTIFIC 1.25" Filter Grey ND0.9 - 0310245 The neutral density filter transmits light uniformly across the entire visual spectrum. It serves as an excellent filter to reduce glare and irradiation when observing the Moon with any telescope 4"(10.2cm) and larger. The ND96 filter may also be employed in the splitting of close double stars where one of the binary pair significantly exceeds the other in brightness. What ist a color Filter for and do we really need it? Color Filters darken the light slightly, that reaches the eye or the sensor of the camera. This eliminates for instance stronger transitions. The result is that your picture turns out with more contrast which automatically shows more details. FEATURES Made from high-quality optical glass Filter glass is absolutely parallel All optical surfaces have anti reflex coatings Filter housing from black anodized aluminum Filter threads on both ends (female/male) Multiple filters usage is possible SCOPE OF DELIVERY 4pcs color filter 4pcs protection-case

EXPLORE SCIENTIFIC 1.25" Variable Polarizing Filter
Universally usable variable polarizing filter with a  1.25" filter thread.This variable polarizing filter allows for a continuous adjustment of the image brightness. This is very helpful to level strong differences in contrast of different observation objects individually. Particularly for lunar and planetary observations but also for solar observations this filter prevents an outshining of details.Solar observations ONLY together with an adequate solar filter !!! Particularly when a Herschel wedge is used and with large objective lens apertures the use of the variable polarizing filter can reduce the brightness of the observation object to a confortable level. The large adjustment range of 40% to 1% light transmission and the neutral grey filter effect create a comfortable and unadulterated image.The handling is very simple. The desired filtering level is set by turning the two sides of the housing against each other.A 1.25" filter thread on both sides (female/male) allow for the simultaneous use of additional colour filters.FEATURESvariable polarizing filterindividually adjustable image brightnessmade from high-quality optical glassblack anodized aluminium housing1.25" filter thread on both sidesSCOPE OF DELIVERYpolarizing filterprotective box
