Product description

The Antlia ALP-T Dualband 5nm Ha&OIII filter is a dual-band pass filter designed primarily for use with one-shot colour cameras (OSC), such as DSLRs and astronomical OSC cameras. It can also be used as a narrowband filter for monochrome cameras to save time when shooting. The advanced multi-coating of the Antlia ALP-T Ultra Dual Band Filter effectively isolates the red H-alpha and blue-green OIII spectrum of emission nebulae, while unwanted wavelengths caused by light pollution, moonlight and airglow are almost completely suppressed (optical density = 4.5).

The result is that the ALP-T Dualband 5nm filter produces a better signal-to-noise ratio and better contrast in your images. The filter allows simultaneous capture of the two most important emission nebula lines while suppressing unwanted light pollution. It enables the capture of clean data and reduces the effort required for post-processing to isolate faint details from background light pollution.
