  • Triad filter from OPT - CCD/CMOS Astro Camera Imaging ...

    Triad filter from OPT. Note that low pressure sodium lights peak at 589.3nm while high pressure sodium lights emit at several wavelengths: 569nm 594nm 595nm 598nm (with a dense cluster between 569 and 616 nm). Mercury vapor lights emit at: 365.4nm 404.7nm 435.8nm 546.1nm and 578.2nm. So it looks like this filter would miss these emission lines (that's good).

It is also of an optical grade of material and design so as to reduce any aberrations or ghosting caused by having a pane of glass in front of your lens.

  • Astronomical filter - Wikipedia

    An astronomical filter is a telescope accessory consisting of an optical filter used by amateur astronomers to simply enhance the details of celestial objects (much as with amateur photography). In contrast research astronomers use filters on telescopes in order to understand the astrophysics (such as stellar classification and placement of a celestial body on its Wien Curve) occurring for ...
