The Optic Spacer: is NOT a completely universal part. The Optic Spacer is dependent on which optic you choose to use your adapter on. Each spacer has a range of sizes it can be used with, so you can use your spacer on more than one single optic! Select one of the available options in the drop down using the chart in the pictures as a reference.
IMPORTANT: If you do not see your specific optic listed, select custom then enter your optics Brand, Model and eyepiece diameter in the order notes at checkout.
NOTE: The OG 2.0/3.0 comes with one spacer when you order it. This is an additional optic spacer that works with both the 3.0 and 2.0 versions
