WebJan 26, 2024 · Thank you! I took advantage of the speed of the RASA to complete an image in the very few clear December nights we get in Chicago. I was able to capture the data in two nights, with one night dedicated to H-alpha and the other night with all three narrowband filters. I was very selective with the subframes, especially the H-alpha. WebThese H-alpha filters are much narrower than those use for night H-alpha observing (see Nebular filters below), passing only 0.05 nm (0.5 angstrom) for one common model, compared with 3 nm-12 nm or more for night filters. Due to the narrow bandpass and temperature shifts often telescopes like that are tunable within about a ±0.05 nm.

WebJan 25, 2024 · It enables the transmission of H-alpha and O-III emission lines, and is compatible with fast telescopes from f/1.4 to f/2. Broadband Filters For those looking for a light pollution filter that may help image galaxies and other broadband objects, we recommend a broadband (also known as a multi-bandpass) filter. H-alpha (Hα) is a deep-red visible spectral line of the hydrogen atom with a wavelength of 656.28 nm in air and 656.46 nm in vacuum.
