Heart (IC 1805) & Soul (IC 1848) hanging in Cassiopeia

This is my version of the very popular pair of deep sky objects known as the Heart Nebula (IC 1805) and the Soul Nebula (IC 1848). They reside in the constellation of Cassiopeia approximately 6,000 light-years away. Both of these emission nebulae are relatively large in the night sky and together they are immense at more than 10 moons across which corresponds over 500 light-years. Although the size of these objects are well known I made a size calculator video based on a formula that Gary Imm gave me last year - it works really well as long as the distance is known.

To image this I used my Canon EF 200mm f/2.8L II USM Lens set at f4.0 with a ZWO ASI294MC Pro and an IDAS NBZ filter all set on an Atlas Pro (yes a little overkill). This is one of my favorite setups that I have grown to love for its wide field. I managed to capture 20 hours of usable data although I collected much more but I was imaging when the moon was out and that data was very poor quality so did not use it.

There was hardly any noise as a result of collecting so many frames. The time consuming part of processing was highlighting the OIII region and merging the starless image with the star mask. I am not a big fan of starless processing mainly because I am not good at bringing stars back really well but am happy with what I did this time so maybe I am getting better at it.
