Hello all. First time poster and very new to astronomy. Was recommended a Meade as a good mid to long term investment and their ETX series I have just purchased a Meade ETX125 accordingly (link here)
http://www.meade.com/etx/etx_mak.html and was wondering what would be a good binoviewer for it (preferably cheaper). My six year old son and I are coming to grips with a single eyepiece, and I would really love him to see through the telescope for longer without having to pull away when he is straining with a single eyepiece. From what I have read here on the forums, the binoviewers are great for the apparent 3D effect.
