Meade Dielectric Diagonal
Best high-clarity upgrade for serious Schmidt-Cassegrain telescope observers.
This is the essential upgrade for serious observers who want to squeeze every bit of light out of their telescope. By swapping in this dielectric mirror, you trade a standard setup for significantly brighter, higher-contrast views, though you will need to manage the slightly heavier build on your rear cell.
