Our Solar filters have been designed to allow direct viewing or photography of broadband solar phenomena (sunspots, faculae etc).

The filter is manufactured from glass and has a multi-layered metalised coating applied by a process of evaporation in a vacuum chamber. A blend of metals layered together gives a pleasing look to the sun and allows natural colours to be seen.

For safe and secure observation the glass filter is sealed in a high-precision black anodised aluminium cell, that screws directly onto the thread on the front of the telescope tube.

For safety the glass filter is held in the cell with a precision-machined collar held in place with screws and not glue (or tape!) as in some competitor products. See our range of adaptors to allow fitting to other models.
