| - | The Celestron 8 (C8) is our smallest telescope not accounting for binoculars or finderscopes. The telescope is usually attached to a Celestron Advanced GT mount, which can be can be set up by a single person because of its compact 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. | ||
| + | In terms of type, it is a computer-controlled equatorial system suitable for both visual observations and astrophotography. Thanks to its compact design, it can be easily set up by a single person. | ||

| ^ 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. | | ^ 10 | Before using the telescope you have to tare the rotation axes.
