WebJul 17, 2016 · As for accentuating your Hb and OIII emissions, I would suggest 1) ample IT, and 2) in post processing just work on the GB channels separately (i.e. suppress the R to nil) after stacking. Right at the end you can recombine the R+GB in whatever strengths you wish. #8 AKHalea Apollo topic starter Posts: 1,277 Joined: 17 Jul 2016 WebNov 4, 2014 · That red light has a wave length of 656 nanometers. You'll also see a blue green line and so this has a wave length of 486 nanometers. A blue line, 434 nanometers, and a violet line at 410 …

WebThe difference in data in narrowband imaging. Narrowband imaging is classed as using filters that only allow a very narrow band width of light through them. Traditionally the filters used are. Ha (Hydrogen Alpha) OIII (Oxygen III) SII (Sulphur II) The light wavelengths that these filters allow to pass are as follows. OIII 501nm. WebThe line that appears in the red part of the spectrum is created when an electron moves between the second and third orbit (N=2 and N=3) and the wavelength at which this occurs is 656nm. It 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 ... WebThe strongest hydrogen emission line, the H-alpha line at 656.3 nm, gives H II regions their characteristic red colour. (This emission line comes from excited un-ionized hydrogen.) H-beta is also emitted, but at approximately 1/3 of the intensity of H-alpha. set of 2 kitchen chairs
