Borg 100ED in the 115mm tube.
This is essentially Borg #8101 but with the #7749 instead of the #8317 draw tube. #7749 also fits the 80mm tube assembly. Also included is the #4052 tube baffle and the #7835 focuser. You will need to provide the final adapter for mounting accessories into the focuser (about $25 from Borg). Seldom used so everything is in excellent condition. There is a small ding to the paint job on the dew shield where I accidentally touched it against my mount one night. I can send along a picture if you request one. There are some Borg stickers supplied so you can cover it up if you want to. Or use a little Ford white touch up paint. Nicer than the 80mm setup because you don't get the vignetting caused by the narrow tube so you actually get a full 100mm objective at the focal plane.
New from Borg at about $1950. $1500 Shipped in CONUS. Please ask any questions you have and I'll do my best to answer them.
