SF100 Size 3: 70mm to 85mm AstroSolar

Solar lens filter for observations in white light

• The filter film is tensioned flat between two aluminium rings.
• Freely adjustable tube clamps
• Suitable for all telescope models, with the exception of the Schiefspiegler, and for finderscopes and binoculars

The solar filter is securely fixed to the lens tube or dew shield using four polyamide threaded columns with precisely adjustable clamps. If required, for public tours for example, filters can be additionally secured so that they can only be removed through force.

If damaged, the film can be easily replaced.

Which filter is suitable for your telescope? In the product name, you can see the telescope tube’s external diameter, where the filter fits. You cannot determine the filter size from the telescope aperture as many instruments have a fixed dew shield in place. It is best to measure your telescope’s external diameter and then choose the correct filter.
