Here is a 2x2 mosaic of the Heart Nebula that I made in narrowband (SHO). I shot 18 600 second subs per filter per panel, so 216 subs (before rejection) in total which took me about 36 hours over the course of 8 nights between August 2016 and Jan 2017. Images were taken from my home in central Maryland.
