Ich möchte mein erstes Teleskop kaufen. Ich will Fotos machen lernen und suche viel Leistung fürs Geld..

Die alten Teleskope von Celestron (und Mead) haben eine Altitude-Azimut Gabel Montierung und Goto. Mit einer Pol-Höhen-Wage (pole wedge) kann man die Alt-Azi Montierung fast zu einer vollen equatorialen Goto Montierung upgraden.

Mi einem alten 8" Zoll Refllektor von Celestron (oder Mead) plus pole wedge kommt rund 1000 Euronen günstiger zu einem equatorialen Foto-Teleskop.


Was hat ein Alt-Azi Goto Teleskop noch für Nachteile außer
- wenn GPS Controller rumspinnt, ist das ganze Teleskop hin?
- Es handelt sich meistens um Schmidt-Cassegrain mit einer Schmidtplatte aus günstigerem Lime-Silikat Glass (oder BK7 bei besser Ausführung).
- Die 20 Jahren alten Mead MX 200 haben ja alle das Problem, dass der Primärreflektor durch den dauernden Motor-Fokusshift irgendwann anfängt zu wackeln/ zu verhaken. Auch mit der Justierung kann man den Primärreflektor nicht 100% fixieren.
- Außerdem - insbesondere nach den vielen auf Losmandy Platte umgerüsteten MX200 bei Ebay zu urteilen - bekommen die Mead Goto Controller ziemlich oft elektronische Probleme.

Haben Celestron Alt-Azi Teleskope diese "Mead MX 200 Probleme" auch?

Insbesosondere das Celestron Nextstar 8" SE. Das wird ja auch aktuell immer noch verkauft, obwohl es schon lange am Markt ist.

Was gibt es sonst noch bei Alt-Azi Forkl Mount zu beachten?

@Pegasus
Ich habe mich nun vorgestellt.


Von unterwegs:
Vielen Dank für die Infos zur celestron nexstar und celestron evolution Serie. Das hat mir schon Mal einiges weiter geholfen.

Nur eins habe ich alt-azi Dummbrot noch nicht verstanden. Warum genau dauert die grundausrichtung (das alignment) eines goto alt-azi Teleskops mit polhöhenwage mehrere Stunden? Vermutlich liegt mein verständnisproblem darin, dass ich noch keine equatoriale Ausrichtung kann (weil ich ja noch kein Teleskop hatte). Bevor du dir den Wolf schreibst, geh ich erstmal die KI fragen.

Die KI hat dazu folgendes gesagt:

## Why Polar Alignment Takes Longer with an Alt-Az GoTo Telescope on a Wedge

**Summary:**
Aligning a GoTo alt-azimuth (alt-az) telescope on a wedge to the celestial pole is typically much more time-consuming and difficult than aligning a dedicated equatorial (EQ) GoTo mount. This difference is due to both mechanical design and the availability of alignment aids.

---

### Key Reasons for Longer Alignment with Alt-Az on a Wedge

- **Mechanical Complexity and Lack of Dedicated Tools:**
Alt-az mounts are designed primarily for simplicity and visual use, not for precise polar alignment. When placed on a wedge, the user must manually adjust the mount to point its axis at the celestial pole, often without the benefit of built-in polar scopes, fine adjustment controls, or clear markings[4]. This makes the process fiddly and prone to error, requiring repeated adjustments and checks.

- **No Integrated Polar Scope:**
Most equatorial mounts come with a polar scope or built-in alignment aids that allow for quick and accurate positioning of the mount's axis to the celestial pole[9]. Alt-az mounts, when adapted to EQ mode with a wedge, rarely have such features, forcing users to improvise with external finders or rough estimates, further slowing the process[4].

- **Unfamiliar Setup and Documentation:**
EQ mode on alt-az mounts is often unofficial or poorly documented, leaving users to figure out procedures through trial and error[4]. This learning curve adds significant time, especially for those unfamiliar with the process.

- **Risk of Losing Alignment During Setup:**
Because the wedge and mount are often separate pieces, attaching the telescope after aligning the wedge can disturb the setup, requiring realignment and further prolonging the process[4].

---

### Why Equatorial GoTo Mounts Align Faster

- **Purpose-Built for Polar Alignment:**
EQ mounts are designed specifically to align one axis with the Earth's rotational axis. They feature fine adjustment controls, clear scales, and often a built-in polar scope, allowing users to quickly and accurately align to the celestial pole[9].

- **Streamlined Procedure:**
The process is well-documented and supported by software and hardware aids. Many users report being able to complete the entire setup, including polar alignment and GoTo calibration, in about 15 minutes[1][9].

- **Less Manual Guesswork:**
With dedicated alignment aids and clear instructions, there is less need for trial and error, reducing the time and frustration involved.

### Comparison Table

| Feature | Alt-Az GoTo on Wedge | Equatorial GoTo Mount |
|-----------------------------------|-------------------------------------|-------------------------------|
| Built-in Polar Scope | Rare | Common |
| Fine Adjustment Controls | Usually absent | Standard |
| Documentation & Software Support | Limited or unofficial | Comprehensive |
| Alignment Time | Often several hours[4] | 10–20 minutes[1][9] |
| Risk of Losing Alignment | High (during telescope attachment) | Low |

### Conclusion

Aligning an alt-az GoTo telescope on a wedge to the equatorial pole is a slow, manual, and often frustrating process due to the lack of dedicated alignment tools, fine adjustments, and official support. In contrast, equatorial GoTo mounts are designed for rapid, precise polar alignment with integrated aids and clear procedures, allowing users to complete the process in as little as 15 minutes[1][9][4].
