How to Use an Astrophotography Telescope
An astrophotography telescope is a telescope that enables you to view distant astronomical objects in the sky. It has the ability to capture light allowing you to view the object in more detail. The method of using an astrophotography telescope changes from model to model and brand to brand. Let's take a look at some of the important aspects of using such a telescope.
Step 1 - Aperture and Focal Length
The aperture is the most important aspect of a telescope. Aperture is designed to capture light and bring it to a focus, so that the image being observed can be examined in more detail using an eyepiece.
The next most important attribute is the focal length, which is the distance from the telescope's mirror at which light will come to focus. A telescope with a longer focal length will be able to bring out images in a larger way and give a higher level of magnification. The final aspect focal ratio is the relationship between the aperture and the focal length.
Step 2 - Mounting the Astrophotography Telescope
The way in which you mount your telescope depends on your telescope and camera combination. A T-Mount Adapter is required to attach the camera to the telescope. The T-Mount Adapter will be attached to the backside of the telescope through screws. It also needs to be attached to the body of your camera. With the T-Mount Adapter attached, you would need a tripod and a mounting system to steady the camera and the telescope.
Step 3 - Polar Align the Mounting
Once you have done the mounting, you have to polar-align the mount. This means the right-ascension axis of the telescope needs to be aligned parallel to the earth's axis of rotation. The level of alignment you do here is based on the size of the picture that you are taking and the exposure time. If you are using something like a 50 millimeter camera you would require just some minimal alignment.
When you want to get a sharp image out of a long exposure, you need to keep the telescope's guidestar centered on the crosshairs for the entire time that the shutter is open.
Step 4 - Guide with an Electronic Drive Corrector
Though telescopes have a telescope drive, you still have to do some guiding. Guiding by hand is not enough, so it is necessary to have an electronic drive corrector. This will guide the telescope's drive motor, so that the telescope is guided in the right manner and you can all see and record image motions accurately.
