Originally developed for the Baader Herschel Prism, this tool ensures tension-free mounting and dismounting of hard-to-reach 2″ Baader filters with a milled grip crown. Now available as a standalone accessory, it is an essential addition for managing your Baader filters.

Key Features:

• Effortless Filter Replacement: Designed to simplify the process of replacing filters in Baader Herschel Prisms.
• Compatibility: Suitable for all mounted Baader 2″ filters with Low Profile Filter Cell (LPFC).
• Precise Fit: Not guaranteed for older Baader filters or filters from other manufacturers without grip crowns or with unknown mount diameters.
• Included with Herschel Prisms: Now packaged with the Baader 2″ Cool-Ceramic Safety Herschel Prism Mark II (Visual/Photo versions).

Note:

Ensure compatibility with your filter system before purchasing. This tool is specifically optimized for Baader's filter designs with a milled grip crown.

This Filter Crown Tool is used to unscrew hard-to-reach 2″ filters. This tool was originally developed for use with the Baader 2″ Cool-Ceramic Safety Herschel Prism Mark II – (Visual / Photo) (various versions available) to make it easier to replace the installed filters and is designed for all current Baader 2″ filters with low-profile mounts. (Please note that the fit is not guaranteed with older or different style filters from other manufacturers)

The Baader modern filter cells are very thin-walled in order to provide the largest possible clear aperture for the actual filter. If a filter is tightly fitted and difficult to access (e.g., in a filter changer or in the rotation mechanism of a Herschel wedge), it can easily deform if you grip and rotate it with only two fingers. Deforming the filter housing can cause it to jam even more than before. With this 2″ filter crown tool, the pressure is distributed over a large area so that it cannot deform – just as if you were gripping the entire filter frame with your hand. This gives you a much better grip to twist it out. Furthermore, you don’t have to worry about accidentally leaving fingerprints on the filter surface too!

The new “Filter Crown Tool”, is specifically designed for all modern Baader 2″ mounted filters. This is due to the unique design of our filter cells, which feature a precisely milled “filter crown”. The filter crown tool interacts with this special notch and is only effective when used correctly. Because of these features, the tool is not compatible with filters from other manufacturers.
