WebThe term H II is pronounced "H two" by astronomers. "H" is the chemical symbol for hydrogen, and "II" is the Roman numeral for 2. It is customary in astronomy to use the Roman numeral I for neutral atoms, II for singly-ionised—H II is H + in other sciences—III for doubly-ionised, e.g. O III is O 2+, etc. H II, or H +, consists of free protons.An H I region … WebIt is this line that is called the Hydrogen alpha line and hydrogen alpha filters are designed to block out as much of the spectrum as possible leaving only a very small bandwidth through which light can pass at the H-alpha … WebJun 27, 2016 · It requires a telescope that will be at least f/20 with the ERF applied.
