50mm Guide Scope Centering Rings

This is a simple but helpful model to start with center on your telescope attached guide scope. These are removable rings that help you start with center when aligning your guide scope FOV with your main scope. I have included the STEPs file for adjustment to other guide scopes, but this was specifically designed for the SVBony SV106 50mm guide scope here that has rings with adjustable thumbscrews. Enjoy & Clear Skies!
