I have been trying to capture the milky way with the equipments that I have available at my disposal but have usually failed. This photo is probably my best attempted so for. If you look closely at the stars they were trailing. So next time I'll try to get the stars stop not the when it trailing.
The rule is called "500 Rule". Basically you divide your focal length of you lens by 500 and you should shoot at that shutter speed or faster. I was max on my shutter speed on my camera. If next time I shoot the milky-way I have to use this rule and adjust the ISO to get the best exposure. There's something new to learn everyday in photography and ofcourse new adventures and discoveries along the way.
