Ultimately, the best FOV for you will depend on your needs and budget. If you are serious about astrophotography, then you will want to choose a telescope with a wide FOV. However, if you are on a budget, then you may want to choose a telescope with a narrower FOV.
Focal length
The focal length of a digital telescope is the distance between the lens and the sensor. The focal length determines the magnification of the telescope, which is the ratio of the size of the image formed by the telescope to the size of the object being viewed. A longer focal length results in a higher magnification, and a shorter focal length results in a lower magnification.
The focal length is an important factor to consider when choosing a digital telescope. If you are planning on doing any serious astrophotography, then you will want to choose a telescope with a long focal length. This will allow you to capture close-up images of objects in the night sky.
Here is a table that summarizes the key points about focal length:
| Focal length | Advantages | Disadvantages |
|---|---|---|
| Long | Higher magnification, can capture close-up images | Narrower field of view, can be more difficult to find objects |
| Short | Wider field of view, easier to find objects | Lower magnification, cannot capture close-up images |
Ultimately, the best focal length for you will depend on your needs and budget. If you are serious about astrophotography, then you will want to choose a telescope with a long focal length. However, if you are on a budget, then you may want to choose a telescope with a shorter focal length.
Mount
A good mount is essential for any digital telescope. Without a good mount, the telescope will shake and vibrate, making it difficult to see images clearly. A good mount will also allow you to track objects as they move across the sky, which is essential for astrophotography.
- Stability: A good mount will be stable and sturdy, even in windy conditions. This will help to prevent the telescope from shaking and vibrating, which can ruin astrophotography images.
