These simple movements make an alt-azimuth mount a great choice if you want to use your refractor or catadioptric telescope for observing in the daytime as well as at night. Thanks toour SPIDER radio telescopes is now really possible to make radio astronomy at school because, unlike an optical telescope, they can, Is it possible to make amateur radio astronomy? This often translates into single evening visits with students at the public observatories, so you can not conduct a continuous study. The body of an APO refractor, known as the OTA or optical tube assembly, is also more likely to be made from quality materials and have a precision focuser that is designed to bear the weight of a camera and other imaging equipment. Their long focal lengths make them particularly good for for distant targets such as galaxies and small nebulae.
