Congratulations on your purchase of an Orion 100mm f/9 ED refractor optical tube. Your 100mm f/9 ED has been designed with high quality optics and excellent mechanical construction. The ED glass in the objective lens means you’ll enjoy images with far less color distortion than those seen in a standard refractor, and the smooth Crayford focuser will make getting sharp images a breeze. These instructions will help you set up and use your telescope tube.

Getting Started

The 100mm f/9 ED comes fully assembled from the factory. The telescope’s optics have been installed and collimated, so you should not have to make any adjustments to them.

Please keep the original shipping box! In the unlikely event you should need to ship the telescope back to Orion for war- ranty repair service, you should use the original packaging. The box also makes a very good container for storing the tele- scope when it is not in use.

Attaching the Refractor to a Tripod or Mount

Optional tube rings should be used to attach the scope to a telescope mount. Tube rings with an inner diameter of 100mm (3.9"), such as Orion item #7371, are needed. When using tube rings, you should first attach them to your telescope mount and then lay the optical tube in the tube rings.

Use of Optional Eyepieces, Diagonal, and Finder Scope

The 100mm ED does not come with a finder scope, diagonal or eyepieces in order to grant the user the greatest versatil- ity in customizing the instrument to suit their tastes. However, certain rules for using accessories still apply.

Any Orion finder scope with a dovetail bracket can be used with the 100mm f/9 ED. Simply unthread the thumbscrew on the dovetail mount (Figure 1) and insert the assembled finder scope and dovetail bracket. Retighten the thumbscrew. Finder scopes that do not use a dovetail bracket will need to be attached by other means.

The 100mm ED can use almost any 1.25" diagonal and eye- piece. To install a diagonal, unthread the thumbscrew on the 1.25" adapter (Figure 1) until it is flush with the interior of the adapter. Insert the diagonal and secure it with the thumbscrew. Then insert the eyepiece into the diagonal and secure it with the thumbscrew.

Use of 2" Eyepieces and Diagonals

A feature of the 100mm ED is its ability to also use 2" barrel- diameter eyepieces and diagonals. At low magnifications, 2" eyepieces can give a wider field of view than standard 1.25" eyepieces. This is especially desirable for observing deep-sky objects, as many of them appear quite large, but faint. Please note that the 100mm ED will not reach focus with the 2" eye- pieces unless a 2" diagonal or extension tube is used.
