You get line stars with all of the telescopes you listed? Try using an eyepiece in the guide port and make adjustments. Also, look Sun, 05 Jul 2009 17:34:25 GMT Greg Kaiser http://tech.groups.yahoo.com/group/autoguiding/message/5961 http://tech.groups.yahoo.com/group/autoguiding/message/5961 I seem to get lines for stars using my OAG from Celestron It's very siiliar to the Raidial Guider by Orion...It has the same prizm adjustments and rotates....

With good polar alignment and PEC, you may not need to guide at all.
