Dave, I forgot to tell you which eyepieces I use with the TV-102. I use the 22mm and 27mm Panoptics, the 12mm Type 4 Nager, the 9mm and 7mm Naglers, and the 5mm and 4mm Radians. I also have the 55mm Plossl but I haven't used it since Wolf Creek last year. It has a 3 degree field of view but it is best suited for dark skies. The 35mm Panoptic works well too. I borrowed Rich's last year and got a great view of the Beehive Cluster. I need to buy that eyepiece soon. Debbie
