Check vignettingThis adapter converts your SkyWatcher EvoStar ED focal reducer for direct insertion into any standard 2-inch focuser. It also adds standard 48mm filter threads to the telescope side of the reducer, allowing you to integrate 2-inch filters into your imaging train for the first time.
This nosepiece provides a simple, essential function: it allows the SkyWatcher EvoStar ED focal reducer to be used like a standard 2-inch accessory. By threading directly onto the front of the reducer, it replaces other connection methods with a smooth 2-inch barrel that slides into your telescope's focuser and is secured with compression rings or thumbscrews. This creates a more direct and rigid connection for your imaging setup. The nosepiece also incorporates internal threads for standard 2-inch (48mm) astronomy filters, a feature not natively available on the reducer itself. This lets you attach nebula, light pollution, or color filters to the front of your optical train, right where they are most effective.
Its primary purpose is to allow the SkyWatcher EvoStar ED focal reducer to be inserted directly into a 2-inch focuser. It also adds threads for attaching 2-inch (48mm) filters to the telescope side of the reducer.
Yes. The nosepiece is threaded to accept standard 2-inch astronomy filters, which typically use an M48x0.75 thread pitch. This allows you to add filters in front of the focal reducer in your optical path.
The nosepiece threads directly onto the front (telescope side) of the SkyWatcher EvoStar ED focal reducer, creating a secure, metal-on-metal connection.
