There are two main reasons for needing telescopes: • Mirrors are much cheaper, per unit area, than detectors. As long as there are kid’s science projects, there will be a need for a cheap, easy to build DIY telescope. The light gathering power of a telescope is proportional to the area of the objective lens/mirror, which is proportional to the square of the lens/mirror diameter - bigger telescopes produce brighter images. Add Tip Ask Question Comment Download. THE BASICS – THE PRINCIPLES OF OPTICS A Galileian telescope uses just two lenses. It sounds complicated. Some telescopes made by amateurs even compete with the ones available in the market for sale and can even perform better.

Video of a super simple homemade telescope build with household items, pretty low power – but still cool because its very MacGuyver-esque haha. Step 2: Lenses. So if you want to gather a lot of radiation, it makes sense to build a big mirror to gather all the radiation into a small spot, and put a detector there. They used it at sea to check the flags of distant boats approaching and to decide if they were friends or enemies. h�bbd```b``�� ��#����O@�@ Before you can use the finderscope properly you will need to make sure that the finderscope is aligned to the telescope. ����Bk�sO�Ē2uV��q�rY� � �� U����vŲ�p������rˋ��YV)�lz���U�$����]�+�RC��L�q��1�y�=b��X�Ȟ���vEf_:c��u�#3.�%�/z�{7��7���vG�,}!y��i��-"�Y��V^�'rgGw��U�pjhw^pM&f/y ���ر�U��z��v��h�ö_�`A4�ٚ�(@v�䆼�c#�6-PD&2�6�dW��ʀ�ְP>�.P�����/��{C�l�*%���eQ�j�
