Messier 12 (NGC 6218) from Telescope Live CHI-1-CMOS
From time to time I obtain data sets from remote observatories. One of my favorite providers is Telescope Live with telescopes in e.g. Chile, Australia and Spain. One of the data sets I received, was data from the globular cluster Messier 12, located in the constellation Ophiuchus.
Data calibration and registration and the final processing was done with PixInsight.
The result was as follows:


In the image are 4 quasars. The most distant quasar is:
WISEA J164648.09-020637.5 with a redshift of 2.1 and an apparent magv of 19.8 (SDSS DR17).
