usage because the image in the eyepiece is inverted (upside- down). The eyepiece will also be too low to the ground for comfortable viewing when pointed near the horizon.
Placing the TableTop
One of the great assets of the TableTop is its extremely por- table size. Due to its overall short length, you will find that viewing while sitting down on the ground next to the telescope is the most comfortable. If you wish to raise the telescope off the ground so that it can be used while standing or sitting in a chair, then a platform, such as a milk crate or table can be used.
Using the TableTop on a Tripod
One useful feature of the TableTop line is the inclusion of a
–without a panhead mounted on it. Most photo tripods use either a 3/8" or
Altitude and Azimuth (Aiming the Telescope)
The TableTop altazimuth base permits motion along two axes: altitude (up/down) and azimuth (left/right). Moving the telescope up/down and right/left is the “natural” way people search for objects; which makes pointing the telescope intui- tive and easy.
Simply take hold of the telescope tube opening at the top or the side brace and move it left or right so that the base rotates. Move it up or down in the same manner. Both motions can be made simultaneously and in a continuous manner for easy aiming. This way you can point to any position in the night sky, from horizon to horizon.

Altitude Tension Adjustment
When aiming the telescope in altitude, you may find that the optical tube is either too hard to move or does not stay in place. Use the altitude adjustment tension knob to change the amount of tension between the optical tube and the altazi- muth base to find the right level of tension to properly move and balance the telescope. (Refer to Figure 1d to identify the Altitude Tension Knob).
Azimuth Tension Adjustment
In the event that adjustments to the azimuth axis need to be made you will first need to remove the Photo Tripod Adapter. This is very easy to do. Simply loosen and remove the three
To adjust the azimuth tension you will need to tighten or loos- en the lock nut on the circular plate at the base of the tele- scope. This is very easy to do; though it will require the use of two wrenches. The first is needed to hold the bolt underneath the base while the second is used to adjust the lock nut at the top of the base. Because these telescopes are so lightweight it is not unusual that you may be able to spin the lock nut with your fingers. This does not necessarily indicate that the assembly is too loose. As long as the base moves without ten- sion and the base plates do not wobble further adjustment is not necessary. (See Figure 11.)
Focusing the Telescope
