How to Use and Preservation

1. How to Use
2. When practicing at the beginning of use,practice focusing on a distant view during bright hours during the day,look through the eyepieces and use the focus knob to fine-tune the focus of the blurred object, it is recommended to start from low multiple, that is use the eyepiece with larger number, do not install the Barlow lens, and increase the multiple slowly after getting familiar with it.
3. Due to the high multiple, the field of view of the astronomical telescope will be small, so itis not easy to find the target. In the daytime, you can first set a target through the optical viewfinder, adjust it to the same picture of the optical viewfinder and the main mirror tube, and in the evening, you can find the observation object from the optical viewfinder and watch it in the main mirror tube.
4. If the target moves in the field of vision, it may be caused by eyepiece shaking. When you find this phenomenon, you need to hold the eyepiece with your hand.
5. You can adjust the tightness of the theodolite by rotating the fine movement handle, and adjust the horizontal position by rotating the screw of the level. When grasping the target, itis also very important to adjust the position of the lens barrel.
6. On aclear night, you can use the product to observe the moon. The best observation time is between two days after the new moon and a few days before the full moon. During this time, you can see most of the details of the moon, including crater, moon sea, radiation pattern and so on. You can also target other celestial objects, such as planets, star clusters and nebulae.(If the lens is replaced, refocus first)
7. How to Preservation
8. The telescope is a precise optical instrument, which is designed to be used almost for life and needs little maintenance. If necessary, it must be carried out by the factory. Please keep and maintain it according to the following rules.
9. If the lens gets dust or fingerprints,do not wipe it with a pair of glasses or a handke- rchief. The lens will be scratched and difficult to see.
10. Use a camera blower to remove small debris.
11. Gently wipe off fingerprints and other stains with a cotton swab soaked with a lens cleaner.

Troubleshooting

Q: I can’t see the target when I look at the eyepiece, I have take off the dust cover,|t’s as blank and fuzzy
A:

1. Please make sure that the cover of the eyepiece needs to be removed before use.
2. If you use this telescope for the first time, we don’t advise to install Barlow lens at first, it is difficult to focus. You can use this Barlow lens after you use the telescopes a few times.
3. Try to use 25mm eyepiece at the first. And then use 10mm eyepiece after you use the telescopes a few times.
4. The telescope can be used during the day and at night, If you can’t see the target through the eyepiece, please adjust the focus with the turn knobs on the side of the telescope, You’ll see the eyepiece lengthening and shortening, and that’s how to focus the object.When replacing different magnification eyepiece or installing
   Barlow Lens, refocusing is needed. The larger the magnification is, the more difficult it is to find the target. Patient and accurate focusing are needed to find the target.

Q: Is there a piece with this to set a smartphone on and take pictures?
A: Yes, it comes with a smartphone bracket and a remote control, which is very easy to install and use. The remote control comes with a connection manual. Please read this instruction carefully.

Q: Why the Optical Viewfinder is inverted of the target?
A: Please noted that it is normal, as the view finder use the special optical lens, all of telescopes optical viewfinder has this situation. Please don’t worry, it is not defective.

Q: What is the difference between two different multiples lens and what is the Barlow Lens?
A: The target can be magnified by 16 times for the 25mm eyepiece, and the 10 mm eyepiece can enlarge the target by 40 times, and the larger the magnification, the smaller the target will be seen by the eyepiece and the clearer. The Barlow Lens can be enlarged twice on the original basis. The focus should be re focused if you change the lens. We suggest that the 25mm eyepiece should be used first, which will be better to find the target and focus.

Points to Note

1. After changing the lens, you need to focus again. If the magnification is too large, you may not find the target. Please be patient with focusing before looking for the target
2. Please don’t aim at the sun, it will hurt your eyes
3. When storing, put a desiccant together and store in a well-ventilated place to prevent mold due to moisture.If possible, we recommend that you keep the tripod open and the lens barrel in place in a well-ventilated room.
4. The optical view finder is inverted for targeting. It is normal not defective.
