Horsehead Nebula with IC 434 from my own observatory and remote

The Horsehead nebula in front of the emission nebula IC 434 is located in the constellation Orion.

2023 I obtained a data set of this object from Telescope Live with telescopes in e.g. Chile, Australia and Spain. In 2017 I photographed the Horsehead- and the Flame Nebula from my own backyard.

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