IC1848 / Westerhout5 or the Soul nebula is an emission nebula in the constellation of Cassiopeia and it is my first ever two panel mosiac, which means it is made up of two separate stacked images, imaged over a couple of nights from my back garden.
Total Integration time: 18 hours 40 mins
Moon coverage: 75-85%
Location: Northern Hemisphere
Bortle: 4
The deep sky object and nebula image below is absolutely vast and is only a small part of a wider nebula called the heart and soul nebula. I have imaged the heart of the heart nebula and you can see this image here.
The Soul nebula taken from my back garden on the west coast of Scotland.
The Heart Nebula is an emission nebula, 7500 light years away from Earth and located in the Perseus Arm of the Galaxy in the constellation Cassiopeia. It was discovered by William Herschel on 3 November 1787. It displays glowing ionized hydrogen gas and darker dust lanes in and around this wonderful nebula.
This is probably one of my best images to date so far and I am so happy I actually managed to finally achieve a two panel mosaic.
This image was taken over several nights back at the start of 2025 with a total exposure time of over 18 hours.
I then stacked all of the data in Pixinsight and processed it in Pixinsight also, to produce this wonderfully vibrant image of this amazing nebula.
Below is what each of the different master stacks look like starting with the Oiii, Ha then Sii filters and you can see that the Oiii is the weekest of all signal. The black edge on the Oiii is stacking artefacts when the alignment is slightly out.
This is of course only one of the panels in my master light stack, but hopefully you get the idea.
I then stacked the other half of the mosaic and processed the same way, then aligned both of these master lights in Pixinsight to produce the colourful image shown above.
