Hi, I am using Celestron Nexstar 6SE since last 2 years and for the first time I am facing issue regarding image formation on the eyepiece. Since last week every thing was fine. The images were very clear. Today when I installed my telescope to see the moon, there was no image formation of moon through the eye piece. There was bright light. Tried adjusting the focus through the knob but it did not work. I took out eye piece and checked directly through the star diagnol. The image was clearly visible through the star diagnol. So I tried checking different eye pieces. But in all the eye piece the problem was same. Kindly suggest as what to do. Thanks and Regards V.Srinivasan
