The mirror cell in my 12.5" PDHQ split tube consists essentially of 3 lobes or vanes, each with a metal clip at the end to hold the mirror. The mirror rests on...
... Jerel, both of my discovery pdhqs, 12.5 and 17.5, have had the mirrors glued to the cell. For a closed tube scope it's hard for me to imagine doing it any...
