Astrophotography is a hugely enjoyable hobby for amateur and experienced
astronomers alike, allowing you to capture the spectacular views of the heavens
seen though your telescope night after night. The equipment needn’t be high end.
35mm, Schmidt and CCD or Digital telescope cameras can be used and all produce excellent
results.
Other useful equipment you will need alongside your telescope is a shutter cable
for the 35mm, equatorial telescope camera mount, a T mount and a guider eyepiece. The
equatorial mount, T mount and guider eyepiece will all help you track and keep
in frame the celestial object you have chosen to photograph as it moves across
the night sky.
There are many variations on which equipment to use and how to set up your
equipment.Try different methods using the equipment you have and see which is
the most comfortable to use and produces the best results. One method is to set
up your camera and mount it on to the side or back of the telescope. The other is
to have the camera on a movable mount or tripod. Which ever method you use, your
camera should be firm and steady and not affected by vibrations from you or the
equipment.
Your camera should be set to pick up as much light as it possibly can, so check
shutter speed, sensitivity and aperture settings to gain the highest quality
picture possible. Try altering the focus and settings to see which produce the
best results This is where digital cameras come into
their own, as you can see
the results as soon as the picture is taken. This allows you to either delete and adjust
your settings to try again, if the picture hasn’t worked out
or sit down and marvel at a beautiful picture that will stun astronomers and the general public world wide...
After you have transferred the pictures to a computer, you can alter them
further in order to get the best possible picture. If they appear grainy, try
reducing the size (zooming in rather than cropping) to get a clearer picture.
For the adventuresome, try setting up a telescope video camera that will take frames at a very slow rate...
