I've replied, Susy,

From another inquiry I've had, I can look at making a dob mount for you if you have an existing OTA. The way I make these mounts, the OTA is able to be readily removed from the dob craddle and used on your other mounts - no alterations are done to the OTA.
This is no commercial venture, so I hope I haven't crossed any terms of use issues. If so, mods. please let me know.
