The problem of traveling to Finland

In February 65438, I saw the Northern Lights in Finland. I think this is the most beautiful natural phenomenon in the world. I sent you the raiders I used before. According to statistics, the probability of seeing the Northern Lights in the northernmost part of Lapland, Finland is 75%. ? Look at the aurora raiders:? Aurora is actually not green, the real aurora is actually colorful, but because the light is too strong, we always look green when we see it. If exposure value is used correctly in photography, the aurora on the negative will have a rainbow-like color. Time: From autumn to winter, you can see the aurora on a clear night. It also happens in other seasons, but it can only be seen in the dark night sky, so it is advisable to have shorter sunshine time from September to April. Location: Northern Lapland Province. Recommended location: Hunter's Cabin in Victoria (with skylight). Transportation: Helsinki takes a direct flight from Finland to rovaniemi, and then takes a bus to Victoria. Features: Skiing during the day and watching the aurora at night. Special meal: The log cabin restaurant bakes the freshest venison under heavy snow and drinks the purest wine. Aurora appearance time: the best time period is 20: 00 pm–1:00 pm. It usually appears 2-3 times a night, and the duration of one time is about 1 hour, while the time of various optical fibers is only about 10 minute. Note: Watch "Aurora" in turn at night. Don't sleep, not for a moment. It is best to prepare an 8-fold telescope. Clothing: Wear leather clothes, gloves, ear caps and large leather boots indoors after the appearance of Aurora. Prepare equipment: It is recommended that you use a camera that can be exposed for a long time. Cameras that use batteries should pay attention to heat preservation. The lens should be wide-angle or fisheye lens. The film should be a high-sensitivity film above ISO400. There must be a tripod and a microswitch. Pay attention to let the camera adapt slowly outdoors, and don't rush it, or there will be ice fog on the lens. Especially for film cameras, the overwinding must be slow to prevent the volume from being broken, and there must be an outdoor transition time, usually 5 minutes. Prepare more batteries. Video recording: If you use a home video recorder, you need to have a slow shooting device so that you can shoot on a full moon night.
