How to Use a Canon D-EOS on a Telescope

T-mount adapter

Though there are other uses, the most common reason for attaching a camera to a telescope is to take pictures of celestial objects like stars and planets. Canon's digital EOS cameras can be attached to telescopes using special adapters. The prime focus method is the easiest way to attach a camera to a telescope.

Things You'll Need

• T-mount adapter
• Telescope that can support the weight of the camera

Instructions

1. Purchase a Canon T-mount adapter, a tube with a T-ring on one end and a tube that replaces the telescope eyepiece on the other.

2. Mount the T-ring on your Canon D-EOS camera just like you would a lens.

3. Unscrew the eyepiece from the telescope and remove. Insert the other end of the Canon T-mount adapter into the telescope and screw into place.

4. Aim the telescope at your subject. If you are new to astrophotography, the moon is a good subject to learn on. Adjust the focus by using the focus knob on the telescope.

5. Take a picture. It is best to use a remote shutter since touching the camera or telescope during the picture can create wobble and blur the image.
