I need a sight tube for my f4 Dobsonian. I've only had this scope for a few weeks and just recently collimated it pretty close to correct (better views of Jupiter than I get with NP101) but have the wrong size sight tube for my scope and need the 2" model.
I like the Astro Systems Light Pipe Sight Tube/Cheshire Combination Tool but can't seem to find it anywhere except eyepiecesetcetera.com. The problem is his site simply refuses to allow me to complete a purchase so I have to call him and it clearly puts him out. It's simpler if I buy somewhere else.
Does anyone know who else carries the 2" f4 version?
What are you guys using for a sight tube?
