I have a 48" long 10" OD Parallax aluminum tube for sale. It is unpainted and the ends have been rolled by Parallax for strength. Because the focal length of the mirror I purchased was longer than expected I had to get a longer tube. This tube is like new except for three holes (120 degrees apart) that I drilled at one end to hold a mirror cell. There are no other holes. Current price for a similar tube as listed on the Parallax website is $151 plus shipping. This would be a great tube for an 8" F5 scope. I'll sell and ship in CONUS for $115. I'll take a personal check, MO or PayPal.
