IC1805 Heart Nebula and IC1848 Soul Nebula

One of the last deep space objects I captured on Crete are two visually large nebulae. And these are IC1805 Heart Nebula and IC 1848 Soul Nebula. Both are very dim objects, therefore I set the shutter speed of the Canon EOS 6Da camera to 3 minutes and let it capture the light shooting from the constellation Perseus the whole night long. Even NGC 884 869 Double Cluster fit in the field of view.

IC1848 Soul nebula

Soul nebula is a beautiful HII region, where new stars are being born. It’s located in the constellation Cassiopeia and it’s 7500 light-years from Earth. The nebula has a neighbor Heart Nebula (IC1805). One can say that in this constellation the heart and soul are close to each other.

As usual, I used narrow-band filters to capture this spectacular nebula. It didn’t fit into my field of view; this means I would need a shorter focal length.

Update 2023-05-07. I returned to this data and reprocessed it, using the latest post-processing know-how. I learned a lot in the last few years, and Pixinsight got very useful plugins. For example, Blur Exterminator sharpens the data, but it still looks realistic without any artifacts. However, the biggest difference is the white balance of the picture. I used the rainbow SHO technique published by
lukomatico.
