I got a very unusual set of perfectly matched 6" F27.5 mirrors, and am using them in the spectrohelioscope. I made cells for them, put the two cells on a large base, and made them adjustable for focus. They can be adjusted together, and one can be adjusted separately to account for any discrepancies.
