consider the height that you want your eyepiece to be, and if possible plan on sitting on a comfortable
chair or stool. Very long optical tubes need to be mounted higher or you will end up crouching or lying
on the ground when looking at objects near the zenith. However, a short optical tube can be mounted
lower so that there is less movement due to vibration sources, such as wind. This is something that
should be decided before going through the effort of polar aligning the mount.
Camera adapter
To attach a camera to your telescope you may need an adapter to get the camera focused. Some
reflectors require wider motion range than the one allowed by the focuser; some Maksutov-Cassegrain
and refractor telescopes are designed to be used with diagonal mirrors and thus need a longer focal
length when used with camera. To achieve that, simply attach an extender to the focuser of your
telescope and then attach the camera with a T-adapter to the extender (fig. 15).
