DGM Optics™ OA-Series™ instruments offer some of the finest optics and
innovative mechanical design utilized by any telescope available to the amateur
astronomer today. Outlined here are basic procedures to help you attain optimal
performance from your OA-Series™ telescope.
After your Scope Arrives
Once you have received your OA-Series™ telescope carefully unpack all
components and inspect for any damage that may have occurred during
shipping. Although it is rare for damage to have occurred during shipping, it is
very important to contact DGM Optics™ so a claim can be filed as soon as
possible with the shipping company.
The Basics: Pre-Alignment
Depending on your model, all the OA-Series™ telescopes require some assembly.
The OA-4.0™ ™ is easiest of all the OA- Series™ telescopes as far as assembly and
requires only that the primary mirror is installed in the tube assembly and the
split yoke is secured around the circumference of the tube assembly. To install
the primary mirror, carefully unpack the primary mirror and remove the (3)
machine screws that are attached to the large platter. Then, with the small
orientation hole in the large platter aligned with the focuser, gently slide the
entire assembly into the tube and, using the predrilled holes in the tube attach
the mirror cell and primary to the tube assembly. Next set the tube assembly in
the "Split Yoke". Placing the split yoke assembly around the tube assembly and
securing it by clamping the adjustable draw latch on the split yoke does this.
Caution: Adjust the draw latch only as tight as is needed to hold the tube
