Description

Antlia ALP-T Dual Band 5nm Ha+OIII and SII+Hb Filters Package

The Antlia ALP-T dual band 5nm filter is a dual line-pass filter which was designed to be used primarily with one-shot color (OSC) cameras such as DSLR’s or astronomical OSC cameras. It can also be used as a narrowband filter for monochrome cameras to save imaging time. The advanced multi-coatings on our ALP-T ultra dual band filter effectively isolates the red Ha and the blue-green OIII lines light from emission nebulae, with almost total suppression of optical density (OD)4.5 on unwanted wavelengths from light pollution, moonlight, and airglow. The result is that our ALP-T dual band 5nm filter creates a superior signal-to-noise ratio and better contrast in your images.

The filter enables the capture of the two main emission nebulae bands at the same time, whilst suppressing unwanted light pollution. It enables you to capture cleaner data and reduces the post processing efforts to isolate faint details from the background light pollution.

Application and Performance:

Engineered specifically for use with DSLR, CMOS, and CCD color cameras

Suppression of optical density (OD)4.5 on unwanted wavelengths adds signal-to-noise

Extremely steep bandpass edges minimize internal reflections

Ideal flat-top and moderate bandpass reducing spectrum down shifts

Ion Gun Assisted Deposition coating technology on the double-sided polished substrate making it the most consistent and accurate light pollution suppression filter

Designed to suppress artificial lighting from Bortle scale 1 to Bortle scale 8

Near IR (NIR) is blocked up to 1100nm

 

Not Recommended:

Solar imaging

Night visual observation

Not Permitted:

DO NOT LOOK AT THE SUN WITH THIS FILTER

Serious eye damage will result if you fail to observe the warning
