| - | ===== C8 (Under construction) | + | The Celestron Advanced GT mount is our entry-level mount, primarily used with the C8 and [[en:osst| OSST (Coronado Hα Solar Telescope)]]. With a payload capacity of up to 12kg, it can also carry a number of other telescopes and cameras. However, it is only equipped with a mount for the Vixen prism rails. |

| - | ^ 1 | One needs carefully choose the place where the telescope should be placed. For example, the relevant part of the sky needs to be visible (the dome covers part of the sky when the telescope is setup on the roof) and the cable connections for the power supply or the cameras should not become tripping hazards.

First the counterweight bar needs to thread into the opening of the declination axis. Afterwards the screw at the end of the counterweight bar can be removed and the counterweight can be place and fixated on the counterweight bar. Subsequently, |

The tube is equipped with a so-called dove tail (the orange thing) that allows a quick and easy attachment of the tube to the mount. Simply, insert the dovetail into the clamp of the mount and tighten the screw of the clamp. |

| - | ^ 10 | + | ^ 10 | Before using the telescope you have to tare the rotation axes. First lose the clutch knobs fixing the right-ascension axis, until you can freely move the telescope around this axis. Now adjust the position of the counterweight such that there is no movement along this axis anymore. Tighten the clutch knobs again and repeat this procedure for the declination axis. As there are no counterweights for this axis, one has to shift the tube along the clamp to tare the declination axis. | {{ost:c8:IMG_7108_small.jpg? |
