Optolong CF (Clear Focusing) Broadband Filter 1.25"/2" Mounted (OPT-CF-125/OPT-CF-2)

Optolong CF (Clear Focusing) Broadband Filter 1.25"/2" Mounted (OPT-CF-125/OPT-CF-2)Optolong Clear focusing filter is designed to highly pass the visible spectral region 420 680nm at 98. 5% transmission. Main Use Use of astrophotography filters, especially narrowband filters, often results in dim images which can be difficult to focus. Clear focusing filter can be used first to clearly focus the image. Use with modified DSLRs for higher efficiency and sensitivity by passing visible range with 98. 5% transmission. Act as an
