SF100 solar filter Size 3: 70mm to 85mm

Lens sun filter for observing in white light

• The filter foil is clamped flat between two aluminum rings
• Infinitely adjustable clamping on the tube
• Suitable for all telescope designs with the exception of the Schiefspiegler, also for finder scopes and binoculars

The solar filter is securely fixed to the tube or dew cap by means of four threaded columns made of polyamide with a precisely adjustable clamping effect. The filters can be additionally secured if required, eg for public tours, and can then only be removed willfully.

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

In the event of damage, the film can be easily replaced.

Which filter fits your telescope? In the product name you can see the range of the outer diameter of the telescope tube that the filter fits. It is not possible to deduce the filter size directly from the telescope opening, especially since a dew cap is permanently attached to many instruments. It is therefore best to simply measure the outside diameter of your telescope yourself and then select the appropriate filter.
