WebMay 7, 2012 · All nebulae exhibiting hydrogen emission are observable with an H-beta filter. If the H-beta emission is stronger than the O-III doublet, the H-beta filter will provide a better view than will an O-III filter. These nebulae tend to be of low surface brightness, where the degree of excitation is not particularly high. WebAs an H-beta filter has to transmit only a single emission line at 486 nm, the band width can be smaller than with an OIII filter. The filter shown above (Lumicon) has a transmission of almost 96% on the H-beta line with a band width of only 9 nm. UHC filters transmit both the OIII and the H-beta lines and are therefore necessarily broader.

WebIn nuclear physics, beta decay (β-decay) is a type of radioactive decay in which a beta particle (fast energetic electron or positron) is emitted from an atomic nucleus, transforming the original nuclide to an isobar of that nuclide. For example, beta decay of a neutron transforms it into a proton by the emission of an electron accompanied by an …
