Abell 5148/50 (Spare Tyre Nebula) 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 HSO data from the planetary nebula IC 5148/50, located in the constellation Grus.

Data calibration and registration and the final processing was done with PixInsight.

H was assigned to the red channel, O was assigned to the blue and green channel. The result was as follows:
