Elephant Trunk Nebula (false color image)
This is my first attempt to create a false color image. The image was created from the raw data of the above photo. The Hα / OIII image data was extracted and then reassembled using the RGBHOO method. Unfortunately, I am still missing the RGB data, which I still have to create as soon as the weather is better again.

Horsehead Nebula
Captured on 18. Feb 2023
Exposure time: 36 frames 480 sec
Total exposure time: 4 h. 28 min.
After waiting for about 1.5 years, I was finally able to take him in.

The Horsehead Nebula is a part of a dark cloud in the constellation Orion, which stands out in front of the red glowing emission nebula IC 434 with a silhouette similar to a horse’s head. The nebula is about 1500 light-years from Earth and appears a quarter the size of Earth’s moon. Due to its equatorial position it can be observed from all inhabited areas of the Earth, but because of its low brightness it is only visible with telescopes of 20 cm or more.
