What are the technical difficulties of focusing-free telescopes?
1. A high-precision photoelectric sensor CCD is required.
2. Ultra-high-speed data acquisition and processing technology is required
The photoelectric sensor output is subject to acquisition and digital processing. In order to achieve high precision focusing, further research is needed on data acquisition and digital signal processing.
3. High-resolution, high-response focusing drive actuators
For fast focusing, the focusing system must also have high-resolution, high-response focusing drive actuators, and execute current commands through closed-loop servo control technology.
4. Research on focusing algorithm and software
Due to the high precision requirements of the focusing system, the fast data processing speed and the large amount of data, it is necessary to have high efficiency and high stability algorithms and response mechanisms.
Due to the technical difficulties of focusing-free telescopes, most ordinary telescope manufacturers are far behind and discouraged. Only some big brands and well-known brand merchants dare to conduct relevant tests, and due to the long experimental period, high trial and error rate, and many technical difficulties, not all manufacturers who invest in research and development can develop qualified products. The author understands that, so far, the most mature products of the focus-free telescope series are mainly American Phonics and German Stelox.
Due to the advantages of fast focusing, no manual adjustment, strong timeliness, and high definition, the focus-free telescope can be described as "must be used" in some high-demanding occasions, mainly because traditional telescopes are fundamentally Incompetent.
Special purpose of focus-free telescope:
1. Watching football games (football games, basketball games), etc.
2. Watching concerts, etc.
3. Watch horse racing, racing and other events.
Due to the unique characteristics of the focus-free telescope, such as timeliness, these characteristics are unmatched by traditional telescopes. If you apply traditional telescopes to fast-changing occasions such as watching football games, concerts, and racing cars, you will often miss many wonderful moments. This is also impossible. Traditional telescopes are slow to respond and require manual focusing, which is time-consuming and labor-intensive. It is indeed a bit laborious to use in these specific occasions. At this time, the focus-free telescope comes in handy, and you can stretch your hands. In addition to these specific occasions, it can also be used in traditional application scenarios, such as traveling. Moreover, it is worth mentioning that the weight of the professional focus-free telescope is not as heavy as imagined, and there is no increase in the weight of the body due to the addition of a complex focus-free system. On the contrary, this type of professional focus-free telescope simplifies many unnecessary designs, making the body lighter and more portable. Generally speaking, it is only about 500 grams, which can be easily used by the elderly, children, and women, and it is very portable. Bring it, I believe it will add a lot of luster to this trip.
