Antlia ALP-T Dual Band 5nm Ha+OIII Golden Filter, 2" Size

Antlia ALP-T 5 nm 2" Dual Band Hα+OIII Golden Astrophotographic Filter

Experience unparalleled astrophotography with the Antlia ALP-T 5 nm 2" Dual Band Hα+OIII Golden Filter, a premium tool crafted for capturing the stunning beauty of the cosmos. This filter is designed to transmit the key Hα (656.3 nm) and OIII (500.7 nm) bands, providing versatility for photographers using DSLR, color, or monochrome cameras. By allowing simultaneous exposure to these two essential spectral lines, it accelerates your signal acquisition process, ensuring detailed and vibrant cosmic images.

Exceptional Features for Superior Image Quality

With an incredibly narrow half-width of just 5 nm for each transmission band, the Antlia ALP-T filter ensures a high signal-to-noise ratio. This results in enhanced image sharpness and contrast. The complete separation of the Hα and OIII bands, combined with exceptional optical efficiency and high optical density, effectively blocks unwanted light, allowing you to capture breathtaking images even near urban areas affected by light pollution.

Important Note: This filter is not suitable for visual observations and must never be used for solar viewing!
