Who will use the F70076 astronomical telescope

First of all, the astronomical telescope you purchased is suitable for observing the Moon, Venus, Mars (not recommended), Jupiter's Circle and Europa and Saturn's rings, as well as brighter nebulae and star clusters (such as the M31 Hercules globular cluster and the Orion Diffuse Nebula M42).Among them, the sr4mm of the eyepiece and if I remember correctly should not be recommended, (the imaging is not good, the chromatic aberration is serious, if you are using a refractor), the H20mm eyepiece with a 700mm focal length objective lens is 35x, which is suitable for observing the moon, the eyepiece with a 700mm focal length objective lens is 56x, which is suitable for observing the moons of Venus and Jupiter, and if it is combined with a 2x extender, you can observe the polar crown of Mars. Since your telescope is so small (only 76mm) that you can only observe brighter objects, hehe.

The use of the F70076 telescope requires a certain amount of professional knowledge and skills, so it needs to be operated by professional observers or astronomical enthusiasts. This telescope is a large-aperture reflective telescope with high resolution and magnification, making it suitable for astronomical observation and photography. When using, it is necessary to adjust the focus and calibrate the optical axis before it can ensure the clarity and accuracy of the observation.

In addition, the configuration and use of telescopes also need to be adjusted accordingly for different observation needs. For example, if planetary observation and photography are required, you need to choose the right eyepiece and camera; If you need to observe deep-sky objects, you need to choose the appropriate filter and time.

In conclusion, the use of the F70076 astronomical telescope requires certain professional knowledge and skills, and needs to be configured and used accordingly according to different observation needs. If you are not a professional observer or an astronomy enthusiast with no relevant experience, it is recommended to operate under professional guidance.

1 After adjusting the optical axis of the primary mirror and the finderscope to parallel, after installing the telescope, we first select a relatively large building target, such as a chimney, an outdoor unit of an air conditioner, etc. Don't care about the old finder scope, first choose the eyepiece with the maximum f value equipped with the telescope and install it on the primary mirror (usually 20mm or 8mm), and use the primary mirror to slowly find the object you are looking at.

2 Adjust the primary mirror of the first bad finderscope The image has been set, so let's adjust the finderscope. Turn the three screws on the finderscope and slowly adjust, adjust the amount of the image in the center of the primary mirror to the center of the crosswire of the finderscope, be patient, this may be the most anxious time.

3 The purpose of the above two links is to make the optical axis of the two lens barrels parallel, not to observe a certain body, and it must be understood.

4 With the optical axes of the two mirrors parallel, we can observe all objects. The specific operation is as follows: after moving to the approximate position, first observe and aim through the finderscope, put the object to be observed in the middle of the cross of the finderscope (it is to rotate the tripod, not the finderscope), after reaching the center, observe the primary mirror, you will find that the observed object honestly appears in the field of view of the primary mirror, and the adjustment of the focal length will become clear.

This is because the optical axes are parallel. Extended Data Astronomical telescopes are an important tool for observing celestial bodies. There are generally two mirror tubes on astronomical telescopes, the larger one is the primary mirror, which is used to observe the target; The small one is called a star finder, which is used to find a target, and is also called a scope.

The eyepiece is a separate individual, it is an item that determines the magnification, and there will be an F number on the eyepiece, which is the focal length of the eyepiece, and the F value of the primary lens is divided by the F value of the eyepiece currently in use, which is the current magnification.

Summary. This telescope is not very good, the average 70076 is a ball cow, the image quality is not very good, and the edges are blurred. And the caliber is not large, and you can't see anything dull.

Generally, the ultimate magnitude of a telescope is the aperture (in mm), that is, the ultimate magnitude of this telescope is about 11. The magnification of a telescope is equal to the focal length of the primary mirror divided by the focal length of the eyepiece, and the focal length of this telescope is 700, and the magnification is 70 if you use a 10mm focal length eyepiece. Generally, the effective magnification of the telescope is equal to 2* aperture, and because it is a ball cow, the magnification is lower, so the effective magnification is about 100.

In general, it is not recommended to get this telescope.

What can the F70076 telescope look at.

The crater of the moon can be seen.

What else can you see?

It can be seen as Mars as far away, but it is not too clear.

Can you see Saturn's rings?

Unseen.

Summary. In fact, there is no way to say how far the telescope can see, and the usual "can see 2000 meters" and "can see 3000 meters" are actually false propaganda of some inferior products.

In fact, there is no way to say how far to see in the Wangyuan Bochang stuffy mirror, and the fast stop of Pingji Bending is often "able to see 2000 meters" and "can see 3000 meters", which is actually a false propaganda of some inferior products.

When the weather is good, you can see the moon 300,000 kilometers away without a telescope, directly with the naked eye, and when the weather is not good, there is dust or fog, even if you use a telescope, you may not be able to see the traffic lights 200 meters away, right? Hehe. So, there's no such thing as how far you can see – this has nothing to do with telescopes, it has to do with weather, air conditions, and observing late-track targets.

It can only be regarded as a toy-grade telescope, and the aperture is not large, and the larger the multiple, the darker and more ambiguous.

Just use a magnification of 30x, no matter how big this telescope is, you can't see anything at all, the aperture is too small. See the scenery only within 15 times. 675 times is simply a lie, and the 675 times magnification caliber must be at least 406mm or more, otherwise it is impossible to achieve.

The astronomical telescope is not difficult to use!

1。First use the finderscope to find the observation of the observant of the target, and then adjust the sail to observe the leakage! The higher the magnification, the more troublesome the fixed focus becomes!

Eyepiece ......There should be an instruction manual. The eyepiece is very tolerant and easy to assemble. You first study carefully, whether you directly install the extender, but not the eyepiece (my first installation is like this, directly look at the extender, do not use the eyepiece Li Yu...).Walk in the air....If you can't finish it yourself, come to me, and I'll send you a specific **.

This telescope is a bull ball, which is not very good to be honest. It is not recommended to buy, although it is cheaper, but the performance is also very poor. Here's a shot of the moon.

Saturn, Jupiter is too blurry to shoot **.
