• **Determining Correct Solar Filter Size**: The solar filter should slip over the sky end of your optical tube. Measure the outside diameter of your optical tube using a ruler, tape measure, or caliper. Measure from the outside of the casing on one side, across the center, to the outside casing on the other side. Order a solar filter with an inside diameter slightly larger than your measurement. For example, if your measurement across the end of your optical tube is 4 inches (102mm), choose a solar filter with an inside diameter of 4.25 inches (114mm)—just larger than your measurement.
