Both Lobster and Cat’s Pas nebulae are located in the constellation Scorpius, both are approximately 5’500 light-years from us. I tried to photograph the Lobster Nebula before, but it wasn’t an easy target due to very low southern declination. From the southern hemisphere, it is much easier. So I took the opportunity when I was in Namibia and tried to capture both nebulae in one shot.
The composition of this picture was not correctly selected, but in the end, both are in the field of view. Here is the picture processed in the “fake” Hubble palette:
