Description

Here is Heart nebula (IC 1805) in widefield captured from my remote observatory located in central Texas. I used an Optolong L-Extreme filter to capture the narrowband (NB) data. From the NB data, Hydrogen-alpha (Ha) and Oxygen (OIII) signals are extracted to create the blue color. 

Integration: RGB: 22,800s (6.33 hours) 600s x 38
Narrow Band: 63,600s (17.67 hours) 600s x 106

Total: 24 hours.
