Camera.I use an old mechanic SLR camera which is independent upon batteries to work. When you take pictures of the night sky the exposure time tends to be very long and if the camera is dependent of batteries it will stop working very fast. It is often very cold when you are outside under a clear night sky and that doesn't improve the situation. The camera should have a B or T setting so you can decide how long the shutter should be open. A lockable shutter release cable is also a must have.Today the most SLR:s are dependent of batteries to work, so if you
want to find a mechanical one, you will have to look at the used market.

Film.Nowadays I only use colour slide films to take pictures of the sky. My favourite is Kodak Ektachrome 1600. It can be very hard to find because it is a professional film and isn't for sale in the common photo stores.I have also tested negative colour film but have run into problems.
The difficulty is the development and the production of copies which
I can't do myself but is dependent on a photo lab. I haven't yet found
a lab which can make good copies. Sometimes you don't even get
any copies, they say that there weren't any pictures on the film. Then
it can also happen that the film has been cut in the middle of the pictures
and there is no way to correct it. Therefore , when you leave the film
for development tell them not to cut it. |
Tripod.A tripod is necessary when you want to take a photograph of the night sky. The exposure time tend to be very long and it's not possible to hold the camera without movement except for a very short time. The Earth rotates and if the stars are not be lines on the picture you must have some way to follow the stars movement in the sky.I have solved this problem by mounting the camera on my eqvatorially mounted tripod, to which I have built a RA motor drive. |
