I have made two focal reducers from lenses i have collected. The first
was made from a 4cm focal length lens that i attached to the nose of
the lpi. Below can see a photo of the jupiter graze taken using it.
The second one was made using an 18cm focal
length objective lens that i obtained from an old spectoscope
telescope. This i force fitted into the opening in an old rubber
eyepiece guard from a microscope. this when trimmed is a push fit
into the back of the opening in the back of the lx90 . I made this one
up and tested it on the moon by taking a pictures of copernicus with and witout the reducer. No perceptible chromatic abberation. I estimate the apparent focal length to be about 1000mm, F5. You might get a similar lens from a pair of binoculars or small finder scope. What do you think of the results of the second setup i only wish i had it for the jupiter graze.
