Congratulations on your purchase of a TableTop telescope. The TableTop will provide years of enjoyment of many night-sky treasures including breathtaking views of the Moon, planets, and even some bright deep sky objects. The Maksutov-Cassegrain and refractor models are also suitable for exploring terrestrial vistas.

Your new TableTop is easy to setup and use. It will arrive almost fully assembled out of the box! Only the visual accessories need to be installed. These include the EZ Finder II Reflex Sight, the eyepiece, and in the case of the GoScope 80 and StarMax 90, the diagonal.

The following instructions will help you to get the maximum performance from your new telescope, please read them thoroughly.

TableTop Parts (refer to Figure 1a-d):

All TableTop Models:

25mm (20mm for #9541 and #9549) eyepiece: The eyepiece is the part of the telescope that you actually look through to see things. The focal length of the eyepiece and the telescope determines the magnifying power. Magnification is discussed in more detail in the Using Your Telescope section

10mm eyepiece: The higher-power eyepiece that comes with the TableTop. Eyepieces are discussed in the Magnification section.

EZ Finder II reflex sight: This is a special “finder” that helps you aim the telescope and locate objects in the sky for viewing. The EZ Finder II generates a red LED “dot” that shows where your telescope is aimed. The use of the EZ Finder II is discussed in the Getting Started section.

Optical tube: This is the main component of the telescope.

Altitude tension adjustment knob: By tightening and loosening this knob, you can change the amount tension in the altitude (up/down) motion of the telescope.

Altazimuth base: This wooden base provides a stable base for the telescope. It allows you to move the telescope in altitude (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 focuser 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 optical 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

Dovetail Holder: Secures the telescope into the mini-Dob style mount by holding the dovetail bar preinstalled on the telescope tube.

90° Star Diagonal: An adapter used on refractor and catadioptric telescopes that positions the eyepiece to a more comfortable viewing angle and provides a right side up image.

GoScope 80 TableTop:

Objective Lens: The glass lens or lens system at the front end of the optical tube. This is the light-gathering source for the telescope.

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

Dovetail Holder: Secures the telescope into the mini-Dob style mount by holding the dovetail bar preinstalled on the telescope tube.

Assembly

Assembly of the TableTop is very easy. Carefully remove the protective packaging. Your TableTop arrives from the factory with the optical tube attached to the base – just install the visual accessories and you will be ready to start viewing with your new telescope! These accessories will be found in a box within the main box. Please save all original packaging. This will help protect your TableTop if you wish to transport it or in the unlikely event repair service is necessary.

When unpacking the telescope it is suggested that you save the internal packaging. In the unlikely event the product needs to be returned the shipping materials can be re-used to ensure it arrives safely at its destination.

Installing the Optical Tube on the Base

Your new TableTop telescope arrives with the optical tube already attached to the base. If for any reason you wish to separate the components this is easily done. It may be helpful to loosen the Altitude Tension Adjustment knob and rotate the telescope so that the Telescope Securing Knob is in a more accessible position. While holding the optical tube with one hand loosen the Telescope Securing Knob until you can lift the optical tube out of the Dovetail Holder. The included dovetail is compatible with most other Orion mounts and many other brands as well. The female threads on the bottom are ¼"-20 and will fit standard photo tripods.

To re-install the tube onto the base make sure the Dovetail Bar is flush with the edge of the Dovetail Holder. Place the Dovetail Bar into the Dovetail Holder so that one of the indentations in the bar aligns with the Telescope Securing Knob and tighten until secure. We suggest using the center indentation to achieve the best balance point. Depending on your accessories you may determine a different position best suits your needs.

Attaching the EZ Finder II

80 & 90mm Models

Slide the base of the EZ Finder II bracket into the dovetail holder that is pre-installed on the optical tube. The EZ Finder II should be oriented so that it appears as in Figure 1. Tighten the thumbscrew on the dovetail holder to secure the EZ Finder II in place. (See Figure 2.)

100mm Model

Remove the two metal thumbnuts from the optical tube. Place the bracket of the Red-dot finder on the tube so that the holes in the bracket slide over the two threaded posts on the tube. The EZ Finder should be oriented so that it appears as in Figure 1. Thread the thumbscrews back onto the posts to secure the Red-dot finder in place. (See Figure 3.)

Operating the EZ Finder II Reflex Sight

The EZ Finder II reflex sight makes pointing your telescope almost as easy as pointing your finger! It’s a non-magnifying aiming device that superimposes a dot on the sky, showing exactly where the telescope is pointed. The EZ Finder II works by projecting a tiny red dot produced by a light emitting diode (LED), not a laser beam, onto a lens mounted in the front of the unit. When you look through the reflex sight, the red dot will appear to float in space.
