With the included accessories attached
to the Apertura Dobsonian Telescope,
balance is achieved with these initial
settings (see pictures).
NOTE: When other accessories are attached
to the OTA, the balance point may change and
appropriate adjustments to this these settings
may be required.
Move the OPTICAL TUBE over onto
the BASE HOUSING assembly.
TIP: The metal seam of the telescope
tube should be turned to the side of
the base that has the handle (BASE
FRONT).
TIP: The flat sides of the SILVER SIDE
BEARING ASSEMBLIES should be facing
up (flat).
TIP: Tightening or loosening the black,
plastic knobs of the side bearing
assemblies is how you will adjust the
tension of the bearings. If excessive
tension is required to balance the
telescope (e.g. because of heavier
eyepieces/accessories), then you may
need to adjust the balance point of the
bearing assemblies as described in
Step 2 above.

Questions and answers
How do I insert the lens into the focuser
How do I set the balance point for my apertura eight telescope with the stock items/attachments I received with the telescope. In other words, what settings do I tighten the screws on the side Optical tube supports for the standard balance point?
To set the balance point for the Apertura Dobsonian Telescope using the stock items and attachments:
1. Align the Silver Side Bearing Assembly with the same holes on both sides of the Optical Tube.
2. Insert the top bolt first but do not tighten it yet.
3. Slide the Bearing Assembly up if needed and insert the bottom bolt.
4. Repeat the process for the other side of the Optical Tube.
5. The position of the Bearing Assemblies determines the balance point and may need adjustment depending on installed accessories.
6. With the included accessories, the balance should be achieved using the initial settings provided.
7. If additional accessories are attached, adjust the Bearing Assembly positions accordingly.
8. When placing the Optical Tube onto the Base Housing, ensure:
- The metal seam of the telescope tube is turned toward the handle side (Base Front).
- The flat sides of the Silver Side Bearing Assemblies face upward.
9. Use the black plastic knobs on the side to fine-tune balance if necessary.
By following these steps, you can achieve proper balance for smooth operation.
