And another happy owner. I still have a sonotube 10"f4.5 Meade starfinder. The mirror is a diffraction limited optic, the collimation holds enough for some pretty tight astrophotos, and I used the thing visually for well over a decade without any issues with the tube. I moved the mirror up the tube, put in an oversized secondary, reamed out the focuser hole for a larger low profile 2", and never felt bad doing it :-).
cheers,
Andrew.
