Cassegrain Telescopes
May 26th, 2010
A favorite of astrophotographers due to adaptability to all types of astrophotography and the ease of attaching camera attachments. This is the telescope with a wide, compact tube that is always mounted on a tripod. The eyepiece is found towards the rear of the telescope. A Cassegrains telescope uses a combination of lenses and mirrors to focus the inbound light into the eyepiece. These work well for both within the solar system imaging and with deep sky imaging. The extra width make its light gathering powers so good,and particularly with viewing faint celestial objects.
