ASTROTRACER
By making full use of its GPS module, Electronic Compass and SR mechanism, the K-1 simplifies the astronomical photography of celestial bodies, without the help for an equatorial. Based on the latitude data obtained from GPS satellites and other affecting factors (the camera’s direction and horizontal/vertical tilt) obtained by its various sensors, the K-1 calculates the movement of celestial bodies, then synchronizes the movement of its image sensor with that of celestial bodies with great precision. Since it captures stars without a streaking effect even during extended exposures, you can record faint stars, which are difficult to detect with the naked eye, as point images.
- The user is advised to use a tripod to stabilize the camera.
- The user is advised to read the operating manual thoroughly before shooting.
- ASTROTRACER cannot be used with some shooting modes, such as interval shooting and interval composite shooting.

별 사진을 찍을 때 지구 자전에 맞춰서 이미지 센서를 움직여준다네요.
당연히 카메라는 고정되어있어야합니다.
재미있는 기능인데 게시판 찾아봤는데 소개된 내용을 못 찾아서 올려봅니다.
다만 얼마만큼의 회전을 지원하는지는 나와있지 않네요.
중복이면 삭제하겠습니다. :)
K-3ii부턴 바디에 GPS를 내장하며 모듈이 없어도 지원하더라구요.
이 센서가 손떨방처럼 축따라 움직이는게 아니라 방향을 바꿀수 있는 구조로 되어있으면 평소에 안정성 문제는 안생기려나요
