Figure 1b: The StarMax 90 TableTop Telescope

Altazimuth base: This wooden base provides a stable base for the telescope. It allows you to move the telescope in alti- tude (up/down) and azimuth (left/right).

Photo Tripod Adapter: This allows you to attach your TableTop base to an optional photo tripod. It has a 3/8" female thread and a pre-installed ¼"-20 adapter to fit virtually all photo tripods.

Rubber feet: Three feet provide support for the TableTop and are skid free. This allows you to place the TableTop on smooth surfaces.

Focus Wheels: The focus wheels are used to bring objects into focus. By turning them, you move the rack-and-pinion fo- cuser in and out.

Eyepiece securing thumbscrews: These thumbscrews are used to keep the eyepiece secure in the focuser.

SkyScanner 100 TableTop:

Primary Mirror: The mirror at the rear of the optical tube gathers incoming light and focuses it with its parabolic shape.

Secondary Mirror: The secondary mirror is located near the opening of the optical tube and reflects the focused light from the primary mirror into the eyepiece.

Focuser: This is where the eyepiece is inserted, and how sharpness is adjusted. Details of the focuser are shown in Figure 8.

StarMax 90 TableTop:

Corrector plate: The lens at the front end of the optical tube designed to correct the aberration inherent in the design of the spherical primary mirror.

Primary Mirror: The spherical mirror at the rear of the opti- cal tube gathers incoming light and reflects it.

Secondary Mirror: The secondary mirror is mounted on the corrector plate and reflects the focused light from the primary mirror into the eyepiece.

Focus Knob: This knob makes an internal adjustment to the optics to adjust the sharpness of the image
