The numerical resolving power "R" should not be confused with the resolution or bandpass of an instrument system (See Section 2). Theoretically, a 1200 g/mm grating with a width of 110 mm that is used in first order has a numerical resolving power R = 1200 x 110 = 132,. Therefore, at 500 nm, the bandpass

Hbeta 5nm Bandpass. Hbeta filters are also useful for imaging nebulae and objects rich in ionized hydrogen. At 486.1nm, a narrowband filter is required to separate Hbeta from nearby blue and green spectral lines. Although weaker than the Halpha line, this is often used for visual detection as the longer red wavelengths of Halpha are
