Rho Ophiuchi Sadr Astro-1
Rho Ophiuchi region, there are 7 hours of integration in LRGB with Red Cat 51 Petzval Telescope, ASI6200mm pro 61-megapixel full-frame Mono camera on Paramount MX 6 mount, 146 shots of which in L 20x180 seconds, in R 45x180 seconds, in G 28x180 seconds and in B 53x180 seconds, processing with Pixinsight. All data and shots were acquired with SadrAstro. Rho Ophiuchi (ρ Ophiuchi / ρ Oph) is a star in the constellation Ophiuchus. 395 light-years away from the Solar System, it is associated with one of the closest star-forming regions to us, the Rho Ophiuchi Cloud. Rho Ophiuchi appears in the night sky as a star of magnitude +4.63, therefore visible to the naked eye as long as you have a perfectly dark and clear sky. It can be observed in the southwestern region of the constellation, almost on the border with Scorpius, three degrees north of the bright Antares and a little NE of σ Scorpii.
Located 23° south of the celestial equator, ρ Ophiuchi is a star in the southern hemisphere. Despite this, its possibilities of observation in the northern hemisphere are quite wide: it is in fact observable up to the 67th parallel N, that is, up to the Arctic Circle; only a large part of Greenland, the northernmost regions of Canada and Russia, as well as Iceland and part of Sweden and Norway are excluded. However, in the regions of northern Europe, southern Canada and central Russia, it will appear very low on the southern horizon and visible only for a few hours. The chances of observation improve as you move towards the temperate and tropical regions of the northern hemisphere. On the other hand, this same declination means that the star is circumpolar only further south than the 67th parallel S, i.e. only in the regions of the Antarctic continent.
The best time for observation coincides with the months of the northern summer, since the Sun is on the opposite side of the ecliptic; in particular in the weeks around the end of May and the beginning of June ρ Ophiuchi is visible throughout the night. On the contrary, in the weeks between the end of November and the beginning of December the star is not visible at all due to the very close sunlight; This period of invisibility lasts longer in the northern hemisphere than in the southern hemisphere, due to the southern declination of the star.
