1.
Put the telescope tube and mount (10) onto the tabletop or full length tripod (6), and attach
by turning the tripod attaching wheel (5) clockwise until snug. Spread the tripod legs apart.
When in this mode, the tabletop tripod will probably work better. However, if you are using the
full-length tripod, place and turn the tripod tray (11) clockwise to lock. Set the telescope on a
steady table or on the ground for viewing.
2.
Attach the microscope adapter tube (9) by sliding it on the telescope tube and mount
(10) until snug.
3.
Release the up and down locking wheel (4) by turning it counterclockwise and level the
microscope to a comfortable observing angle and then tighten it by turning clockwise.
4.
Open the slide holder cap (7) and place the microscope or astronomy image slide into
the holder.
5.
Close the slide holder cap (8) and aim to a light source.
6.
Flip the right or left eye adjustment (2) into position so that you can see through the
Why Do I See Upside Down?
One of the most surprising discoveries first-time telescope owners will find is that images
may appear upside-down depending on the type of telescope. The first thought is the
telescope is broken - when in fact it is working perfectly normal. Depending on the type of
telescope, images may appear upside-down, rotated, or inversed from left to right.
Why is this? Why would you want to see everything incorrectly? All telescopes, refractors,
reflectors, and catadioptrics, as well as all cameras, have inverted images because that’s the
way all lenses and mirrors work. Even the lenses in your eyes invert the images of the world,
and your brain erects them. Astronomers usually don’t bother adding the optics needed
for an erect image because extra optics reduce light throughput and introduce aberrations.
Who cares what’s up or down in space anyway? For astronomical viewing, it is not important
whether an object is shown correctly. In space there is no up or down!
