as the target,adjust the 3 screws of the viewfinder, so that the viewfinder and
telescope eyepiece observed the same goal
Remove the eyepiece from the zenithoscope and attach it to the eyepiece interface
of the photo holder
The eyepiece attached to the photo frame holder,the installation of the eyepiece to
the Enhanced Diagonal,rotating the focus knob, in the eyepiece to see distant objects
clearly.
In the photo frame bracket sucker set up mobile phones,mobile phone screen through
the observation,so that the lens at the middle of the eyepiece.
Adjust the tripod,aiming at the sky target(For example:the moon, the plant), mobile
phone camera in the app to enlarge the target shooting.

What to Look For in the Sky
There is a whole universe of objects to be seen in the night sky so where does one
start? Well lets examine the most visible objects first
The Moon
The moon is the easiest target to find in the night. When it is in the full position, when
the entire face is lit, then it bathes the night with a silvery light washing out the rest of
the sky from all but the brightest objects. The best time to view the moon is actually
not when it is full but rather anytime up to the first quarter, this is when the face
appears to be half lit up. The terminator on the moon, the dividing line between dark
and light, shows the best features such as craters and mountains

What to Look For in the Sky
The Planets
The planets are our solar system companions. These range in size from moon size
rocky bodies to giant gas balls which could hold 1000 Earths. To find the planets
requires some information as to when they are visible. An astronomy magazine such
as SkyNews or Sky and Telescope, will give you the locations of the planets from
month to month. Most people who have looked up at night have probably seen some
planets but did not realize it. A planet, when it is well clear of the horizon will not
twinkle as do the stars. They are resolved by the eye as tiny balls as opposed to the
stars which are infinitely small points of light. The easiest planets to view, when they
are visible, are Venus, Mars, Jupiter and Saturn, Uranus and Neptune. Mercury is
an object to look for but it is usually below the horizon and often is a challenge to find.
Pluto is too small for most telescopes below 10" so do not worry about finding it at this
time.
