Antlia ALP-T dual-band 5nm filter 2" är ett dubbelt linjepassfilter som är designat för att användas främst med one-shot färgkameror (OSC) som DSLR eller astronomiska OSC-kameror. Det kan också användas som ett smalbandsfilter för monokroma kameror för att spara bildtid. De avancerade multibeläggningarna på vårt ALP-T ultradubbelbandsfilter isolerar effektivt ljuset från Ha och de blågröna OIII-linjerna från emissionsnebulosor, med nästan total undertryckning av optisk densitet (OD)4,5 på oönskade våglängder från ljusföroreningar, månljus och luftglöd. Resultatet är att vårt ALP-T dubbelbandsfilter på 5 nm skapar ett överlägset signal-brusförhållande och bättre kontrast i dina bilder. Filtret möjliggör infångning av de två huvudsakliga emissionsnebulosorna samtidigt, samtidigt som det undertrycker oönskade ljusföroreningar. Det gör att du kan fånga renare data och minskar efterbehandlingsarbetet för att isolera svaga detaljer från bakgrundsljusföroreningarna. Som Antlia ALP-T dubbelbands 5nm filter lo oks gyllengult för blotta ögat, vi kallar det också för guldfiltret.

Applikation och prestanda:

  • Konstruerad speciellt för användning med DSLR, CMOS och CCD färgkameror
  • Undertryckning av optisk densitet (OD)4,5 på oönskade visuella våglängder lägger till signal-till-brus
  • Extremt branta bandpasskanter minimerar inre reflektioner
  • Idealisk flat-top och måttligt bandpass som reducerar spektrumnedskiftningar
  • Ion Gun Assisted Deposition beläggningsteknik på det dubbelsidiga polerade underlaget vilket gör det till det mest konsekventa och exakta filtret för att dämpa ljusföroreningar
  • Bra prestanda vid brännvidder snabbare än F3.0 med kontrast som ökar när brännvidden ökar
  • Designad för att dämpa artificiell belysning från Bortle skala 1 till Bortle skala 8
  • Nära IR (NIR) är blockerad upp till 1100nm
