Hey , I'm new to the forum and new to telescopes! I recently stumbled upon an old Edmund Scientific Telescope and brought it home with me. I thought it was to cool looking and too interesting to pass on ! I'm not for sure what it is exactly but from the little I've looked around it seems to be a 4 inch f/15 refractor? It's not complete and was wondering if parts for these are still available ? The mount itself is all there i believe and everything moves freely . The scope tube looks to be all straight no dents or dings in it . But the glass is not mounted in it. I have the lenses and a few other parts that came with it but not sure exactly everything I need to put this back together. Is this scope of any quality and worth the effort to get it back into working order ? Any information on this scope would be greatly appreciated!
