This is the tube from my first ATM project (I subsequently took the optics out & recycled them into another scope). It is a 30cm x 129cm sonotube, painted flat black inside & extremely red outside. It has various holes drilled into it, but is perfectly useable for a 25cm F/5 scope. It also has a basic 1.25" focuser attached.
Free to good home! Pickup only from inner Melbourne. PM me if interested.
