AstroSolar solar filter, 174mm-184mm

With this attachment, you can safely observe the sun. The attachment is simply placed on the front of the telescope's objective and secured with three screws.

This works with both refracting and reflecting telescopes (but not with Dobson telescopes with a truss tube design, of course!).

Please ensure you select the correct size: the product title specifies the outer diameter range of the telescope for which the filter is suitable.

The filter film used is AstroSolar from Baader-Planetarium, which is renowned for its excellent optical quality, with a density of ND5 for visual and photographic applications.
