Hi Mel, I use a William optics binoviewer with my LS60 and LS100 scopes. They come to focus with the 1.6x GPC(glass path corrector) supplied with the BV, but the focuser is almost racked in all the way, with about 5mm to spare. I also use a Coronado blocking filter and the 1.6x GPC is screwed to the nosepiece facing the objective, this way I have plenty of focus range for all my eyepieces. I prefer plossls, the TV 32,20,15mm and 11mm pairs work great, as do the 24mm Pans. Binoviewing, especially with a doublestacked LS100 can produce some fantastic views, I like the 3D effect you get with a full disk, and using higher magnification really makes the detail on the disk stand out, especially in the wings of Ha. I've tried zoom EP's with the BV but didn't find them comfortable in use.
Ivan.
