Here, the shutter speed used is too slow and the stars

have moved a significant distance while the shutter

was open causing them to streak, but not enough to

form full or aesthetic star trails. Instead it just leaves

the Milky Way looking ill-defined and messy. A much

faster shutter speed is required to freeze the stars in

placeforthosepinpointspecksof light.Increaseyour

easier by using a torch to

shed light on what

you’re doing.
