Frequently Asked Questions - Aurora II ExploreOne
How do I set up the Aurora II for the first time?
Attach the tripod, mount the telescope tube, insert the eyepiece and finderscope, then align the finder during daytime.
What can I see with this telescope?
With 70mm aperture, you can see Jupiter's moons, Saturn's rings, the Moon's craters, bright double stars, and some deep-sky objects like the Orion Nebula.
How do I clean the lenses?
Use a blower brush to remove dust, then gently wipe with a microfiber cloth. Avoid liquids; use isopropyl alcohol only if needed.
Why is my image upside down?
Telescopes show inverted images by design. Use an erecting prism for terrestrial viewing, but it's fine for astronomy.
Can I use a Barlow lens with this telescope?
Yes, a 2x Barlow will double the magnification. Use with the 10mm eyepiece for 140x (within max useful limit).
What type of mount does it have?
It has a manual alt-azimuth mount with slow-motion control knobs for fine adjustment.
Is it suitable for astrophotography?
Basic lunar and planetary photos are possible with a smartphone adapter, but the mount is not motorized, so long exposures are difficult.
How do I align the finderscope?
Point the telescope at a distant object (e.g., a treetop). Adjust the finderscope screws until the crosshairs are centered on the same object.
What does the 90° diagonal do?
The star diagonal allows more comfortable viewing by directing light at a 90° angle, ideal for astronomical observations.
Where can I find spare parts?
Spare eyepieces, finders, and diagonals are available on the ExploreOne website or authorized dealers.
