Quote:so here is my question (as odd as it might seem). Is it best to collimate (I use a laser) INside my residence before moving the scope (8" dob) outside,

Quote:The answer is complete the initial collimation inside then take your scope outside and wait until it cools down before checking collimation one more time. It might need little collimation touch up.
