How to assemble astronomical telescope 30070? Are the mirror, zenith mirror and magnifying glass of the telescope installed?

This kind of horizon telescope is relatively simple, because there is no need to aim at the polar axis, just put the tripod flat. After flattening, install the objective lens on a tripod. Most importantly. . Open the objective lens cover (many people don't open the objective lens cover. . )。 As for the zenith mirror, try not to install it (the light will weaken after repeated refraction, which is not suitable for observation). Directly install the eyepiece, the installation order is cheap first, but now it is expensive (relatively speaking, the eyepiece is the most expensive), and the disassembly order is the opposite!

Attached is the instruction manual of Phoenix 30070 astronomical telescope.

1. Telescope focusing and viewfinder calibration

Take out the low-power eyepiece, put it into the eyepiece connecting tube, tighten the screw, push or pull the telescopic tube on the focusing tube by hand (note: F 1000 short tube is telescopic tube) to obtain the telephoto image, and slowly adjust the handwheel until the hand surface is clear. This method can quickly adjust the focal length.

Calibration of viewfinder. If the target of the viewfinder is not clear, adjust the eyepiece on the viewfinder to a clear image. When the target seen from the telescope is not in the center of the viewfinder crosshair, adjust the cross section as follows: tighten or loosen the three screws on the viewfinder bracket to make the viewfinder move up and down, left and right or obliquely. When the target appears in the center of the crosshair, it will be corrected. Then replace the high-power eyepiece and repeat the above procedure. If the target,

Note: use the viewfinder to find the object first, because it has a large viewing angle, which can speed up the initial adjustment. Generally speaking, install a low-power eyepiece first, and then gradually increase the magnification you want. When replacing the eyepiece, make the necessary focusing. Don't be bothered by the images you see. This is normal for astronomical telescopes. The smaller the focal length of the eyepiece, the higher the magnification. For example, the magnification of 4mm eyepiece is higher than that of 20mm eyepiece.

Two. Eyepiece and magnification

This telescope has several different types of eyepieces. The median fatigue of a telescope is closely related to the focal length of each specific eyepiece and primary mirror in the telescope. The formula is as follows:

Focal length of primary mirror/focal length of eyepiece = magnification, for example: 20mm eyepiece magnification = 1000/20=50X. Use of astronomical telescope: loosen the declination locking screw on declination axis and the time angle locking screw on polar axis, and loosen the polar axis height locking handwheel to make it rotate on the circumference. Install the low power eyepiece. Observing the moon or other planets: adjusting the star finder. Put the moon in the center of the reticle. Open the objective lens cover so that the open end is aimed at the moon. Adjust the focal length as described above. Two elastic handwheels are operated by both hands to make the telescope move within a limited distance. When using the elastic handle, pay attention to automatic locking. Please don't push the telescope. If you want the telescope to move in a wider range, loosen the important fastening screws first. Move the telescope by hand and then tighten the screws again. If you need to observe other planets, you'd better observe Mars first, because it is the brightest celestial body for most of the year, except the sun and the moon. Besides, you'll be surprised at the speed at which the planets move. If you point the telescope at a planet, leave it for 5- 10 minutes, and then observe it, it is likely that it is no longer in the telescope's field of vision. Because this equatorial telescope is designed to make it move in any direction, it can track the movement of celestial bodies in the sky. The motion direction of celestial bodies is opposite to the rotation direction of the earth, centering on the earth axis or the celestial axis. As long as the polar axis of the telescope is aligned with the celestial north pole, the telescope can be automatically placed in a position parallel to the earth axis, and the stars in the sky can be found according to the knowledge of constellations and star maps. In short, you point the telescope at the center of the celestial sphere in the sky, just like a hub. It looks motionless. The declination is 90 degrees minus the angle away from the hub. The north pole of the celestial sphere is 90 degrees. If you are in the North Pole, you must point the telescope directly above, because the earth is round and the polar axis should be determined by one of the following two simple methods. Install the telescope at night, loosen the fastening nail of the declination axis, rotate the telescope until the pointer points to 92 degrees on the declination scale, and tighten the screws.

Loosen the handwheel of polar axis orientation and adjust the telescope so that the open end points to the north. You can find the magnetic north by observing Polaris roughly or using a compass, and the true north pole can point directly at Polaris through a telescope, because there is a deviation between the magnetic north pole and the true north pole. Find the latitude of your place on the map, loosen the handwheel of the polar axis height, hit the dial to the correct latitude of your place, and aim the star finder at Polaris. You can also see that Polaris is not in the center of the viewfinder reticle. This may be because your telescope and the ground are not on the same level. Then loosen the polar axis orientation handwheel again, move the telescope to aim at Polaris, and tighten the two fastening screws. Polaris deviates from the celestial north pole 1 degree. So you still need to make some adjustments after looking for stars in the sky.

Quick Star Search: After installing the telescope according to the above method, find out the orientation of a star according to astronomical knowledge. For example, the bright Vega's declination is minus 38 degrees and 44 minutes, loosen the declination fastening screw and push the telescope to rotate to 38 degrees around the declination axis, even though the declination axis of the telescope moves circumferentially to a position about 52 degrees (90 -38 degrees) away from Polaris. In this way, the search work can be greatly simplified. The whole sky is divided into minutes like a 24-hour clock (note: the two indicator stars on the Big Dipper point directly at Polaris, so it is easy to find the center of the celestial sphere). After finding the two indicator stars on the Big Dipper, loosen the fastening screw of the hour angle and move the telescope to aim at the straight lines of the two indicator stars of the Big Dipper (including Polaris, of course). So your telescope will point to the large angle of11h. When rotating the angle dial, make the pointer point to 1 1h and tighten the screw. At this time, your telescope matches your position and time angle. Loosen the angle locking screw, rotate the telescope to the right for 1/4 cycles, and nail the time angle pointer at 18h30 minutes. Observe that Vega is near the center of the crosshair from the star finder, adjust the time angle and the deflection handle until Vega is in the center of the crosshair. In this way, you can observe the sky from the main telescope. As mentioned above, the division of the sky into 24 hours is based on the fact that the earth rotates for 24 hours. Every planet is at a time angle of 0-24 hours. If observed from the true north, each planet is on a concentric circle divided into many degrees. This degree is called declination, due north celestial pole, 90 degrees perpendicular to the North Pole.

Three. Performance and use of optional accessories

magnifier

Take off the reflector, put the magnifying glass into the focusing cylinder and tighten the screws, then put in the required eyepiece, and tighten the screws on the magnifying glass and tighten the eyepiece. After using a magnifying glass, the magnification of the telescope is calculated as follows: the magnification of the telescope = the focal length of the objective lens f/ the focal length of the eyepiece F* the magnification of the magnifying glass.

For example: F 1000 astronomical telescope, H=20mm eyepiece, magnification of 3 times magnifying glass telescope = 1000/20×3= 150X.

Moon mirror (optional)

Screw the threaded part of the moon mirror into the eyepiece hole, then put the eyepiece into the reflector and tighten the fastening screw. This kind of moon mirror can reduce the light intensity and change the observation effect, which is suitable for observing and improving the observation method of scenery under strong light.

Four. preventive measure

Under no circumstances can you directly observe the sun through the star finder, because directly observing the sun will hurt your eyes, and observing the heart of the sun requires accessories for the sun observation mirror.

Verb (abbreviation for verb) storage and maintenance

This product is a precision optical instrument, so it should be handled carefully to avoid violent impact or vibration. When not in use, cover the objective lens to prevent dust and dirt from entering, and don't put the telescope in a place where the temperature is too high or too low or chemical substances volatilize.

When there is dirt on the glass surface of the telescope, brush or wipe it with a brush or mirror-wiping flannel, and don't touch it with your fingers.

If the inside of the telescope is found to be seriously dirty and moldy, or the mechanism is out of order or damaged, please don't disassemble it by yourself, but send it to a special maintenance department and have it handled by experienced maintenance personnel.

Note: all kinds of screws and nuts on the telescope. If the instructions do not indicate the use method, please do not tighten or loosen it by yourself, which will affect the imaging quality and use.
