IC 1274/1275

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 emission Nebulae IC 1274 and IC 1275 in the constellation Sagittarius.

The calibration, registration and the final processing of the Telescope Live data was done with PixInsight.

For the first version I assigned H to the red channel and S to the green and blue channel. The result was as follows:

For the decond version I used all the HSO data and displayed them in the Foraxx palette. The result was as follows:
