114mm 4.5" Long Tube Spherical Mirror with 1" Secondary - Great Value!
NOTE:  Spherical mirrors can be pulled into a parabolic curve by a method known as flexing.  The result is often better than a polished parabolic mirror if done properly as parabolic mirror generally have a rough surface and spherical mirrors generally have a smooth surface.  Here is a link about mirror flexing to answer any questions about it:  http://www.skyandtelescope.com/wp-content/uploads/Adler-MirrorFlex.pdf
