+====== C8 & Celestron Advanced GT ======
-===== C8 (Under construction) =====
+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.
-Das Celestron 8 (C8) ist das kleinste Teleskop im Sortiment, von Ferngläsern und den Suchern abgesehen. Durch seine kleine Bauart ist es auch von einer Einzelperson aufzubauen.
+===== Assembly =====
-=== Der Aufbau ===
-Im folgenden wird nun der Aufbau des Teleskops schrittweise erläutert. Rechts ist der Aufbau im Schnelldurchgang dargestellt
+In the following the setup of this telescope and the mount will be explained step by step:
 |< 100%  1% 30% 40% 25% >|
-|      ^  Anleitung  ^  Genutzte Teile  ^  Teleskopzustand nach Anbau  |
+|      ^  Description  ^  Used parts  ^  Telescope after the corresponding step  |
-^ 1    | Der Aufbauort sollte so gewaehlt werden, dass einerseits der relevante Teil des Himmels sichtbar ist (Auf dem Dach verdeckt die Kuppel haeufig alle oestlichen Objekte) und Kabelverbindungen (Strom, ggfs. Kameras) nicht zu Stolperfallen werden. Der Beispielaufbau im wurde im Praktikumsraum direkt hinter der Tuer gemacht -> im Weg, versteckt und kein Himmel -> **schlechte Wahl** |  |  {{ost:c8:001_resize.jpg?300}}  |
+^ 1    | One needs to 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 a certain part of the sky when the telescope is setup on the roof) and the cables of the power supply or the cameras should not become tripping hazards. The example setup was performed in the laboratory-course room directly behind the door -> directly in the way, hidden, and no sky -> **Bad choice!** |  |  {{ost:c8:001_resize.jpg?300}}  |
-^ 2    | Das dreibeinige Stativ bildet das Grundgerüst des Teleskopes.      |  {{ost:c8:IMG_7078_small.jpg?300}}  |  {{ost:c8:002_resize.jpg?300}}  |
+^ 2    | The tripod is the backbone of the telescope.      |  {{ost:c8:IMG_7078_small.jpg?300}}  |  {{ost:c8:002_resize.jpg?300}}  |
-^ 3    | Die Scheibe zur Stabilisierung fixiert die Stativbeine an der Innenseite. Die Stange, die die Scheibe durchsticht, wird mit dem Gewinde von unten in den Stativsockel geschraubt und zwar soweit, bis das Gewinde auf der anderen Seite vollständig durch ist. Die Stange sollte sich nun vertikal bewegen lassen.   |  {{ost:c8:IMG_7079_small.jpg?300}}  |  {{ost:c8:003_resize.jpg?300}}  |
+^ 3    | This disk is used to stabilize the legs of the tripod from the inside. The rod that punctures this disk will be screwed (with the side showing the thread) from below into the basis of the tripod. This needs to be done until the thread is completely visible on the other side. The rod should now be vertically slidable.  |  {{ost:c8:IMG_7079_small.jpg?300}}  |  {{ost:c8:003_resize.jpg?300}}  |
-^ 4    | Nun wird die Teleskopmontierung auf den Stativsockel gestellt. Dabei ist zu beachten, dass der kleine, verchromte Finger auf dem Sockel zwischen   |  {{ost:c8:IMG_7093_small.jpg?300}}  |  {{ost:c8:004_resize.jpg?300}}  |
+^ 4    | Now the mount can be put on the tripod basis. One has to take care that little chromed pin from the basis of the tripod  needs to be placed in the corresponding housing of the mount.  |  {{ost:c8:IMG_7093_small.jpg?300}}  |  {{ost:c8:004_resize.jpg?300}}  |
-^ 5    | Anbringung der Gegenwichtsstange und der Gegengewichte   |  {{ost:c8:IMG_7080_small.jpg?300}}  |  {{ost:c8:006_resize.jpg?300}}  |
+^ 5    | In the next step the counterweight bar and the counterweights needs to attached to the back-end of the mount. 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 screw can be reattached to the end of the counterweight bar. |  {{ost:c8:IMG_7080_small.jpg?300}}  |  {{ost:c8:006_resize.jpg?300}}  |
-^ 6    | Anbringung des Tubus   |  {{ost:c8:IMG_7104_small.jpg?300}} {{ost:c8:IMG_7109_small.jpg?300}} {{ost:c8:IMG_7110_small.jpg?300}}  |  {{ost:c8:007_resize.jpg?300}}  |
+^ 6    | In the next step the tube needs to be attached to the mount. 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. |  {{ost:c8:IMG_7104_small.jpg?300}} {{ost:c8:IMG_7109_small.jpg?300}} {{ost:c8:IMG_7110_small.jpg?300}}  | {{ost:c8:007_resize.jpg?300}} |
-^ 6.5    | Achsen auswuchten   |  {{ost:c8:IMG_7108_small.jpg?300}}  |  {{ost:c8:007_resize.jpg?300}}  |
+^ 7    | Afterwards the hand terminal and the power supply can be connected to the telescope. Both can be simply plugged into the labeled ports of the mount. For the hand terminal the corresponding holder should be attached to the tripod first, so that it can be safely stored.  |  {{ost:c8:IMG_7092_small.jpg?300}}  |  {{ost:c8:008_resize.jpg?300}}  |
-^ 7    | Teleskopsteuerung anschliessen, Stromversorgung herstellen   |  {{ost:c8:IMG_7092_small.jpg?300}}  |  {{ost:c8:008_resize.jpg?300}}  |
+^ 8    | Subsequently, the cover can be removed from the tube.   |   |  {{ost:c8:010_resize.jpg?300}}  |
-^ 9    | Achsen ausrichten   |  {{ost:c8:IMG_7122_small.jpg?300}} {{ost:c8:IMG_7124_small.jpg?300}}  |  {{ost:c8:009_resize.jpg?300}}  |
+^ 9    | If needed, the sun filter can be attached to the tube. Thread the screws on the side of the sun filter, so that it cannot fall off when the telescope is moving.  |  {{ost:c8:IMG_7121_small.jpg?300}}  |  {{ost:c8:011_resize.jpg?300}}  |
-^ 10    | Abdeckung entfernen   |   |  {{ost:c8:010_resize.jpg?300}}  |
+^ 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?300}}  | {{ost:c8:011_resize.jpg?300}}  |
-^ 11    | Gegebenfalls Sonnefilter anbringen   |  {{ost:c8:IMG_7121_small.jpg?300}}  |  {{ost:c8:011_resize.jpg?300}}  |
+^ 11    | Afterwards the axes need to be justified. To do this, they need to be move to the index positions as illustrated in the image.   |  {{ost:c8:IMG_7122_small.jpg?300}} {{ost:c8:IMG_7124_small.jpg?300}}  |  {{ost:c8:011_resize.jpg?300}}  |
-^ 12    | Alignment ausfuehren, Genau wie am C11, [[en:ost:telescope:c11_bedienung#alignment|hier]] beschrieben   |    |  {{ost:c8:011_resize.jpg?300}}  |
+^ 12    | Now the alignment can be performed. This procedure is very similar to the one of our  [[en:ost:telescope:c11_bedienung#alignment|C11]] with the exception that the mount will not automatically move to the index positions but fortunately you already did this in the step before.  |    |  {{ost:c8:011_resize.jpg?300}}  |
-^ 11    | Fertig   |    | {{ ost:c8:build_c8.gif }}  |
+^ 13    | Finished!  |    | {{ ost:c8:build_c8.gif }}  |
+===== Functions such as Hibernation =====
+The operation of the Advanced GT as well as features like hibernation do not differ from the CGE-Pro and can be found in the article on the [[en:ost:telescope:c11_bedienung#alignment|C11]].
