Removing stars from an image using StarNet++

Using the free StarNet++ software, you can remove stars from an image, leaving only the background (nebula or galaxy). This makes it possible to save the stars separately in a graphic editor (for example, Adobe Photoshop), which ultimately allows you to process the stars separately, the background separately, using different parameters for noise reduction, saturation, etc. In addition, a picture without stars can be quite self-sufficient due to a more interesting display of the nebula.
You can download StarNet++ from the link. The program is free, does not require installation – just unpack the archive, open the folder and run the starnetGUI.exe file. If an error occurs during startup (missing DLL VCRUNTIME140_1.dll), try downloading and installing Microsoft Visual Studio, and then rerun starnetGUI.exe.

The training image file can be downloaded from this link. This is a fragment of an image of the IC 2118 “Witch’s Head” nebula in the constellation Eridanus, which I photographed on November 11, 2023 using a fast Samyang 135mm f/2 ED UMC Canon EF lens, a Canon 550Da DSLR and a Sky-Watcher AZ-GTi mount in equatorial mode . The total signal accumulation was 58 minutes.

Aurora from Murmansk, December 18, 2023

On the night of December 18, 2023, i managed to very successfully catch the aurora. So that the observations would not be interfered with by light from Murmansk, it was decided to go to Lake Lapot. And, as it turned out, it was not in vain – the glow was very bright and large (almost half the sky), the color was clearly visible, and the shape of the glow changed in real time.
