Have an old aquarium or bicycle you don't need anymore? Here is the place to sell your unwanted (non-astro) items to a friendly Singastroian. Your junk might be someone else's treasure! Strictly for non-commerical use only.
I have a big binocular for sale as it is under utilized, Bcos heavy and need a tripod to use. 20x-180x100. It is very sharp but a bit blur or double image when zoom to maximum.
