You must be able to reason out the assembly as the instructions are worthless. Spacer tube comes installed in wrong place. Nothing tells you that but it won't assemble unless you figure out where it should be. Meade needs to address assembly instructions issue. If you assemble it wrong, it won't work correctly. Construction is solid though. Well made part.
Pros: Necessary for Deep Space Astrophotography
Cons: Instructions are poor at best. Don't match part.
