Relatively old stuff from my original web-page...
A Simple Wide-Angle
Guess what, I am lazy.... So, I tried to find as much "completed work"
as possible. Resulting in a rather simple design. All parts can be
easily found on fleamarkets or rallies... The basis of all are a
photographic bellow, a Vesta pro and a couple of lenses (M42).
Cardboard finished the first design, but just have a look...

M44 (Praesepe) recorded with the above setup, unguided camera on a simple tripod,
the bright spot on the lower left edge is Jupiter
