I finally got a Dob and my aperture fever is now under control.
Since I have at least one important question to ask, and this seems to be the first thread on this scope, I thought I'd list the questions (and links to answers) as they come in this OP (opening post) to serve as a reference for others.
1) Bright objects (e.g. Saturn) have an echo image very close to the original. Why?
Is it stray light due to the open truss tube?
