85mm Milky Way Reveal Focus Filter

Description

The 85mm Filter is good up to about a 60mm lens filter size. Over that, you should order a 100mm version which is good up to a 90mm lens filter size. If in doubt the filter size for each lens is generally listed in the front writing on the lens.

How it works: The Goal of the Reveal Focus Filter is to create six spikes (really there are three spikes that pass through the star but if you are counting them one-by-one I don’t want you confused) on bright stars. There is a main large spike then an X of four smaller spikes. The goal is to get the main large spike centered between the X and centered on the star itself. As soon as that is done BOOM you have perfect focus in as little as 2-3 seconds.
