The Heart Nebula on a moonless night

Less than 1 minute Minutes
With a clear and moonless night I had an epic imaging session with the Heart Nebula (IC 1805).
 
From Wikipedia: the Heart Nebula is 7,500 light years away from Earth and is located in the Perseus Arm of the Galaxy, in the constellation Cassiopeia. It was discovered by William Herschel on 3 November 1787. It is an emission nebula showing glowing ionized hydrogen gas and darker dust lanes. The brightest part of the nebula (a knot at its western edge) is separately classified as NGC 896, because it was the first part of the nebula to be discovered. The nebula’s intense red output and its morphology are driven by the radiation emanating from a small group of stars near the nebula’s center.
 
I was able to capture a total of 90 minutes of good light frames (30 x 180 seconds).
 
This time I used my remote setup with Windows Remote Desktop, a mini dedicated astro PC with Windows 10 (a Beelink T34) and NINA advanced sequencer with a plugin (Ground Station) that was sending me email notifications during the session, while I was sitting on my couch.
