Optolong Clear Focusing Filter
The Optolong Clear focusing filter is designed to pass through the visible spectral region between 420nm and 680nm at a high transmission level of 98.5%.
Use of astrophotography filters, especially narrowband filters, often result in dim images which can be difficult to focus. Clear focusing filter can be used first to clearly focus the image as it lets through practically all the light in the visible spectrum.
Use with modified DSLRs for higher efficiency and sensitivity by passing visible range with 98.5% transmission.
Act as an outstanding dust shield, which prevents the possibility of dust settling on the lens during long time exposure.
