Thanks! I understand this solution! I know what to do!

Hi CraigT82, i have a question about the adding of the crayford to the Sky-watcher heritage. Its quite a while ago (2016).... I am a beginner and I think about adding the Crayford to my heritage 150 Dobsoniun. As far I can see on your photo's there is more distance between the eyepiece and the focal point of the second mirror. Is theat a problem or do I need other eyepieces than the pieces that was included at this Dobsoniun. I tried to figure this out online, but I have not enough knowledge about this. Maybe you can answer my question or anyone else?
