Has anyone removed a Coulter 17.5" primary from the red tube scope?
That is, taking it all the way off, cutting or removing the duct tape side support wrap and cutting the silicone glue holding it to the back board?
I think they were siliconed like the smaller mirrors.
I'd like to know if the mirrors were soda lime green or possibly a bororsilicate (Pyrex).
Also if the backs were ground flat, or left tapered and rough from extrusion.
Essentially I'm looking for a quality report on these mirrors.
