Cell for ERF filters and glass solar filters (136mm to 160mm diameter)

This high precision part is custom built exactly for your telescope.

This cell is suitable for energy rejection filters (ERF filters) and solar glass filters. The cell is individually manufactured for your particular telescope and filter. The filter is kept tension-free. Fitting to your telescope can be done to tight tolerances limited only by the measurement accuracy for the tube diameter. The housing can be fixed in place with three plastic screws.

Advantages and features:

• • • • • Custom-made filter cell for telescopes with 136mm up to 160mm diameter sunshades.
        • Customized for your particular telescope. This allows for tight tolerances.
        • Customized for your particular filter.
        • Precision machined from aluminum.
        • Felt inside to avoid scratching the tube.
