WebMay 29, 2024 · Achro 's, apart from widefielders, have longer focal distances. Mostly done to suppress CA. One of the extra's gifts a long focal refractor gives is the longer focal depth. Vulnerability to seeing decreases with longer focal depths. So an f/ 10 refractor is less vulnerable to seeing than a f/ 6 refractor. WebPhotometry is a technique of astronomy concerned with measuring the flux, or intensity of an astronomical object's electromagnetic radiation. Usually, photometry refers to measurement over large wavelength bands of radiation; but, when not only the amount of radiation but its spectral distribution are measured the term spectrophotometry is used.
