So I think I am going to start by building a 4.5" F8 small dob. The primary & Secondary will cost me about $53 (USD) with shipping plus any customs. I sent an email to the customs service to see how much that will be.
The next thing to decide is do I want to make it a solid sonotube or some sort of truss travel scope. I am looking around talpiot for sonotube, and will try to see how much it goes for. From there I can decide if I want to lug the scope around in 1 piece or not. I'm thinking with this one a solid tube makes sense.
