I have a Jason Explorer Model 307 telescope but I do not have a manual and it is missing the eyepieces and lenses that came with it. I have tried Bushnell but have not gotten very far. Does anyone know where I can get the manual and a set of the eyepieces?

Hi. At that level almost all telescopes use .956 diameter eyepieces. The two other standard sizes are 1.25 and 2.0 inches. Just measure. There are many brands and quality levels. That scope 800mm long and has a 60mm front lens. I would look at Orion to start. Have fun! http://www.telescope.com/control/main/

Your replacement eyepieces are probably .965 diameter. Just measure the focuser to confirm the barrel width. These eyepieces are not as popular as they use to be, but many are still available and you should have no problem putting together a set. I would suggest 10mm and 25mm. You don't really need more then that with these scopes.
