Antlia ALP-T Dual Narrowband Ha & OIII 5nm Filter - 36mm Unmounted

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. 

As Antlia ALP-T dual band 5nm filter looks golden yellow to the naked eye, we also call it the Golden filter.

 

Application and Performance:

  • Engineered specifically for use with DSLR, CMOS, and CCD color cameras
  • Suppression of optical density (OD)4.5 on unwanted visual 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
  • Good performance at focal ratios faster than F3.0 with contrast increasing as focal ratio increases
  • Designed to suppress artificial lighting from Bortle scale 1 to Bortle scale 8
  • Near IR (NIR) is blocked up to 1100nm

This finder scope is so easy to set up and use that it relegates my Telrad finder scope into second place, what a lovely piece of kit, I'm really impressed. Thank you ThaiExcite for the excellent service. Jim Mc.
