Telescope

All the constructions are made with the principe of lens to lens. Make a construction to fix the telescope at the camera. With the enlarging and the longer exposure-time, it's not easy to make pictures by hand, so always use a tripod and a cable release.
The cover of an old antenna-amplifier, old adapterrings and a film can are the most important parts of the adapter
No cable release?
DIY! (saw, bore and glue)
And a rubber band to keep the camera fixed in the constuction
