165438+1October 19 The observation site of partial eclipse is recommended as165438+1October/September total eclipse.
At 1 and the last contact, the elevation of the moon was about 14 degrees, which was close to the measuring point on the ground. So you have to choose an unobstructed location in the east to have a chance to observe. I suggest you use the compass of your mobile phone to find the East!
2. After finding the East, straighten your arms and point your ring finger at the ground level. At this time, the height of your index finger is about 5 degrees elevation, which will reach this height more than 20 minutes after the moon rises. If there are no obstacles near your height and you can see a large sky, then your place is a good observation point!
Shooting guide
When observing, you only need to be where you can see the moon; As for shooting, take a mobile phone or camera and other photographic equipment to find a place with a wide field of vision.
First of all, it is suggested to use a SLR or a micro-monocular camera with a telephoto lens to shoot close-ups of various periods of the eclipse. Secondly, you can use a medium-focus lens to shoot, or you can use a wide-angle lens to shoot "series images" representing the eclipse process. In the case of a small astronomical telescope, it is also a good choice to connect the camera body or mobile phone camera to the eyepiece of the telescope through a fixture or adapter ring for shooting. In addition, at present, major mobile phones can also easily photograph solar eclipses. A single photo is taken in automatic mode or night scene mode, and it is recommended to shoot the video or delayed video in the middle focus part. No matter what equipment is used, it is best to prepare a stable tripod to fix the shooting equipment, which can ensure the stability of image quality and picture.
When shooting with telephoto lens, in order to reduce the jitter when pressing the shutter, it is best to use the cable release with interval exposure function to assist shooting. After setting the camera, adjust the lens to M position, aim at the moon with real scene, and manually turn the focus ring to make the moon clearly appear in the view frame. Because the moon is constantly moving in the sky, if you take a close-up with a telephoto lens, you need to adjust the lens orientation from time to time without the help of the equatorial telescope to ensure that the moon will not move out of the picture.
It is best to choose some distinctive landscapes, such as towers, ancient buildings and bridges. Make the photos taken more enjoyable. After fixing the shooting equipment, set the exposure parameters of the camera according to the ambient light. It is recommended to take a photo every 30 seconds or 1 minute. After the shooting is completed, the photos of different periods are extracted and superimposed in the image processing software, and an interesting and vivid "eclipse necklace" picture can be obtained later.
