This is the Borg 4317 helical focuser and 7316 1.25" adapter. It is a supplemental visual focuser to your SCT/Mak's course focuser. Best of image shift. I used it on my ETX, but I sold the ETX and no longer need. It also helps to have the eyepiece farther away from the ETX finder. It also works well on any scope where you need to fine focus. $45 ppd in US, with original box. Make in Japan.
