 OPTOLONG EOS-C L-Pro Clip-on Filter Optical Astronomical Telescopes for Camera Built-in Filter Light Pollution

L-Pro Filter:

    L-Pro is an abbreviation of L-Professional, light pollution restraint and high transmittance of nebulae emission lines.

     L-Pro passes a large amount of nebula emission and blocks certain types of artificial lights, improving contrast efficiency of the object.


L-Pro spectral line of emission:

    High transmittance at OIII (496nm&500nm), Hβ(486nm), NII(654nm&658nm), Ha(656nm)and SII(672nm).
    It would be effective in blocking city Na (589nm/616nm), Hg (435nm/578nm), and other artificial lights.


L-Pro Filter production processes:

    Double Sided polishing process ensured degree of parallelism and flatness above 30" and 1/4λ separately in order to guarantee high image quality.
    Precision optical coating increases the transmittance and blocking depth effectively.
    Electron gun evaporation method.

Main Features:

    Metal frame
    Multi-bandpass light pollution filter for astrophotography
    Very high transmission (~90%) at major nebula emission lines
    Multi-layers anti-reflection coating
   
    WARNING: The filters of Optolong are not designed for Sun observation. DO NOT LOOK AT THE SUN WITH THE FILTER. You would be BLIND if you did not observe the warning.
