Dust Cap Functionality

A little demonstration of how the the dust cap on the Skyward 150 is also an Bahtinov mask and an aperture mask.

The Bahtinov mask is the portion with angled slits. This mask helps improve focus which results in clearer images.

The aperture mask reduces the aperture size which allows you to get more detailed images (as there is less brightness and glare) when viewing bright objects.
