Observing Tip:

If you're planning a permanent installation, using a universal top plate like this allows for precise mechanical alignment and a stable mounting interface—but be sure to check compatibility with your mount’s bolt pattern. Pair with the appropriate iOptron center post, T-bolt, or adapter ring for a seamless fit.
