Guiding photography using equatorial mount or synchronized motor enables the photographer to capture the same number of meteors as stationary photography does. the advantage of this kind of photography is that it helps the astronomer capture the meteor s motion across the star field. this can reduce a considerable amount of calculation work and minimize subsequent errors
利用赤道式腳架，或加上同步馬達所進行的追蹤攝影，所拍得的流星數目與固定攝影完全相同，沒有什麼得益，唯一好處可直接拍得流星在恆星間之軌跡，減少了大量事後計算工作，減少誤差。 -
Use the shuttle release to begin the exposure, which can last for several minutes to an hour. stationary photography is also known as " star trail photography ", since the images of stars will appear as trails because of the earth s rotation. long exposure makes the stars trails overlap one another, rendering the identification of constellations more difficult
這方法拍得的照片，會因地球自轉而令恆星的影像都成了流跡，故又名星流跡攝影，但曝光時間不要太長，使星流跡互相重疊，辨認星座時便非常困難。
