NGC 6250 is a open cluster of stars in the southern constellation of Ara, near the border with Scorpius. [5] It was discovered by English astronomer John Herschel on July 1, 1834. [6] This cluster has an apparent visual magnitude of 5.9 and spans an angular diameter of 18′, [2] with the brightest member being of magnitude 7.6.

During last year's astrophotography expedition to Namibia, I managed to capture the interesting open cluster NGC 6250, which is located in the southern constellation of Ara, near the border with Scorpius.

NGC 6250 is a Star Cluster + Nebula in the Ara constellation. NGC 6250 is situated south of the celestial equator and, as such, it is more easily visible from the southern hemisphere. Given its visual magnitude of 5.9, NGC 6250 is easily visible with the help of a small binocular.

2022年9月6日 · For NGC 6285, the recessional velocity relative to the Costmic Microwave Background is 5665 km/sec, while for NGC 6286, the similar value is 5475 km/sec, yielding an average of 5570 km/sec. Based on that recessional velocity (and H0 = 70 km/sec/Mpc), NGC 6285 and 6286 are about 260 million light-years away.

In my opinion a exceptionaly beautiful open cluster. It is close to my recent Unamed nebula that thanks to Sakib Rasool turned out to be GN 16.57.5. Please log in or sign up to leave a …

2008年11月11日 · NGC 6250 ( ⁠ and ⁠) is a young open cluster, lying in a heavily obscured region within the boundaries of the next inner (Sag-Car) spiral feature. There are several arguments which suggest that the cluster is associated with the prominent dust cloud seen to the east of it.

2016年11月23日 · We have considered the low- and mid-resolution spectra of 32 stars observed with the Fibre Large Array Multi Element Spectrograph (FLAMES) instrument of the ESO Very Large Telescope (VLT) in the field of view of the open cluster NGC 6250, and we performed a detailed chemical abundance analysis of the 19 member stars.
