The Hint on Capturing the Starry Night

Last week the world witnessed the movement of Planets Venus and Jupiter getting closer each day till on 15th March when they were very close by the viewers from the planet Earth. The event was marked with spectacular photographs taken by professional and non professional photographers from all around the world as you can see the one on the right taken from facebook page shared by Fiske Planetarium and many more from Astronomy without Boarder twitpic

As most people would think these images were developed with the aid of computer tools, we would like to get into more insight on the subject by considering the importance of light on taking images like these. An object can only be seen if it has ability to reflect light and for that light to reach sensors in our eyes, sensor in the camera or photographic film in the old cameras.

The more light you allow to get through the aperture of the camera the more the object can be seen, just like the way our eyes can see more clearly when an  objects is reflect more light as compares to those reflecting less. The same phenomena also applies when you are in dim light you tend do open your eyes more to increase the pupil size and allow more light to reach the sensor in your eyes, while tend to squeeze them when looking at bright object to reduce the amount of light.

The working principle of our eye is the same as the one in the camera to be able to capture a nice photo at night or in the day time. The camera has got aperture just like the pupil in our eyes and it’s controlled by shutter. To be able to get a the best image at night or in the evening sky the most important parameter is to control the shutter speed so as to allow more light to pass through the aperture to the sensor.

Depending on the distance between your camera and the object you need to adjust the focal length (distance between lens and sensor) to get a clear image depending on the precision of falling light on the sensor. Focal length is adjusted by using the lenses attached to our camera depending on the distance between the camera and the object.

To avoid getting blurry images it’s highly recommended to avoid shaking during capturing light sensitive objects like stars, planets and comets hence putting a camera on stand is a better way to avoid shaking. With these simple tips you can start practising by looking on the manual of your camera and get familiar with the tools of adjusting shutter speed, focal length and ant-shaking.

Wish small digital cameras you may not be able to change the shutter speed but there might be option on light sensitivity and you can use these instead depending on the light intensity of an object. Below are some photos taken by us with simple digital camera and now it’s your turn to start enjoying the beauty of the sky with your own creativity to it.

Tanzania is still blessed with a beautiful dark skies, a lot more stars from the Northern skies and the Southern skies and still has beautiful landscapes which all together makes an amazing view  when captured at once. Let’s show love to the beauty of nature and the sky above

Let's show love to nature and bring wonders to the world

Together with Astronomy Without Boarders we are saying  Thank you for joining us with “Beauty without Borders: Conjunction of Glory” – the Venus & Jupiter conjunction event.
