Description

A widefield mosaic of the heart and soul nebulae. At the bottom right can be seen the claw nebula. 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. The total time 
Panel 1 (Heart):
Integration: RGB: 22,800s (6.33 hours) 600s x 38
Narrow Band: 63,600s (17.67 hours) 600s x 106
Total: 24 hours.

Panel 2 (Soul):
Integration: RGB: 12,000s (3.33 hours) 600s x 20
Narrow Band: 46,800s (13 hours) 600s x 78
Total: 16.33 hours.

Total integration time: 40.33 hours.
