How long is the 80 Leon? I use a Tak FS60-C, and while it's only 60mm in clear aperture, it does a fine job guiding my FS102 at 820mm f/l. The FS60-C is about 35cm in length including the dew shield, add a little for the guide camera. Very nice when you swap scopes and use the 102 to guide the 60. Great optics in both as you'd know. Monte Wilson also uses an FS60-C to guide his FSQ-106.
