# Remote Shutter Releases Shot's lined up, camera's smiling, you're sitting gnawing at your fingertips in anticipation, then all hell breaks loose. As your finger inches towards the shutter button, your camera shifts by a slight, normally insignificant amount - but your target's now out of frame and you're out of focus. Hence why we use the **remote shutter release** - a device that lets you take photos provided its cable is attached to the camera! With the push of a button, the shutter automatically closes and opens - without you needing to look through the monitor (if the object is static). # Intervalometers In astrophotography, it's important that you take a lot, lot of photos - light is difficult to come by and its impossible to get the entire scene (with the light you can't see with your own eye!) in one shot. Therefore, people take photos when they're up to - a lot, lot of photos! The gold standard for astrophotography is *300* shots - yes, around 2-3 hours of just holding the shutter down. While astrophotography can be exhilarating it's typically besides the average person to crouch on the floor for that long - hence the creation of the intervalometer, a device that will do it for you! %%photo of one - credit creator!%% This device allows you to just sit back and enjoy the stars, taking photos to its user's specifications in regular time intervals. end for now - need to know more about this by using one!
