Daystar Instruments QUARK - okularmodul H-alfa filtersystem för kromosfär

Det första H-Alpha-filtersystemet i ett stycke för refraktorer från f/9 till f/4

Denna nya, allt-i-ett-design kombinerar högkvalitativa komponenter från en telecentrisk barlow, adaptrar, nosar och Daystar alfa-vätefilter i en enkel sammansättning. Genom designeffektivitet och optimering kan användare nu njuta av den kända högkvalitativa optiken från DayStar* till ett överkomligt pris.

För användning på refraktorer av F/4 till F/9 behöver användaren inte oroa sig för optiska konfigurationer. Sätt bara in din diagonal, lägg till ett okular och se.

QUARK innehåller en anpassad Daystar Instruments 4.2X telecentrisk Barlow-lins helt optimerad i beläggningar och optisk design specifikt för Hydrogen Alpha-våglängden. Denna mycket specialiserade telecentriska lins erbjuder överlägsen planhet i fältet.

Exakt filterbandpass kommer att variera beroende på den slutliga teleskopapplikationen, så QUARK-enheter är kvalificerade att visa antingen prominens eller yta (kromosfär). Inget specifikt FWHM-bandpass har angetts. Nu kan observatörer köpa ett filter baserat på deras önskade observationsmål istället för deras budget. Välj prominenser och ytdetaljer (kromosfär). Båda finns tillgängliga för samma låga pris!

Den helt optimerade designen eliminerar behovet av adaptrar. Allt är kombinerat i en lätt enhet i okularstorlek. Den nya, kompakta designkonfigurationen eliminerar onödiga komponenter, vikt och tillhörande kostnader. Vi har till och med minskat strömförbrukningen, så Quark kan nu fungera hela dagen utan ett litet, tillvalsbatteri i handflatan. Bafflar har lagts till för att öka kontrasten och AR-beläggningar är optimerade för våglängden 656 nm.

Versioner

2 versioner: Prominence eller Chromosphere - den här versionen är för Chromosphere (Kromosfär).
