Determining the pseudo magnitude of the o Oph A star using Iris 5.59 software observed from the Astronomy Laboratory, Department of Physics, Faculty of Mathematics and Natural Science, State University of Malang [PDF]
o Oph A star is a star in the Ophiuchus star cluster. o Oph A stands for omicron Ophiuchi A. Ophiuchus is a zodiac between Scorpio and Sagittarius in the current era, the 9th zodiac is calculated sequentially from Aries and finally, the 13th is Pisces. A magnitude scale is a unit for measuring the brightness of a star.

Domesticating Light: Standards and Artisanal Knowledge in Early Astrophysics
Astrophysics was born in the nineteenth century as a “New Astronomy” (in the words of Samuel Langley, 1884), a knowledge built primarily by amateurs who explored deep space by studying the Sun, stars and nebulae.
