Stargazing in Ampucao

Long exposures are commonly used in astrophotography to accumulate faint light from the stars. For an exposure time over 30 seconds, the camera needs to be set to Bulb or Time. With Bulb setting, the shutter remains open while the shutter release button is being pressed, and it closes with the release of the button. With Time setting, the shutter opens with a single full press of the shutter release button, then it closes with another full press. High image quality after long exposure time at high sensitivity is required. By setting the camera with a high ISO sensitivity, a fast shutter speed can be used to achieve correct exposure. This allows easy shooting of the starry sky with the fixed mount method for beginners.
