Inside the mirror box you will see a foam insert that contains some small parts, clutches, extension and the red dot finder. This
foam insert also protects the main mirror during transit. It also gives you the opportunity to store/transport eyepieces or
accessories. Remove the insert and the protective paper from the main mirror. We recommend keeping the soft paper covering
because it can protect the mirror from dust and dirt without giving off fluff.
In the other box there is the secondary cage unit and the rocker box (See figure 5):

Take both parts out of the box and carefully remove the protective paper from the secondary mirror.
Assembly
If you are assembling your telescope for the first time, we recommend doing so in a warm room.
First, place the mirror box onto a table to attach the altitude wheels to the mirror box. You will notice that each altitude wheel has
two holes. One of the holes matches the threaded hole on the mirror box, and the other matches the threaded hole in the lid of
the mirror box.
Important: You have four possibilities to attach the altitude wheel onto the mirror box of the telescope. There are two sets of holes
on both sides of the mirror box. Having two sets gives you an additional degree of freedom to balance your telescope. If you are
just using lightweight eyepieces (1.25”) we recommend attaching the altitude wheels to the lower set of holes. If you are using a
coma corrector, heavy eyepieces or both we recommend using the upper set of holes.
Though the distance of the holes in the altitude wheels appears to be similar, the orientation of the wheels on the mirror box DOES
matter – holes will not align if the altitude wheels are mounted in the wrong orientation. We recommend marking the position of
the altitude wheels so that everything works on the first try next time you assemble the telescope. We recommend using
luminescent color that enables you to assemble the telescope in complete darkness so your eyes can adapt to the night sky faster.
Luminous color or luminous stickers are available from model making sources.
After attaching the altitude wheels onto the mirror box, place the rocker box on the ground and insert the mirror box into the rocker
box. Make sure that the two fans on the back of the mirror box are on the side of the rocker box that has the deep undercut (see
figure 6). Next, you will need to install a clutch on each side of the rocker box. These hold the structure’s weight and enable it to
