Pacman Nebula and Heart Nebula
I made another try at the Heart Nebula, and added the Pacman Nebula onto the beginning.
When the imaging for the Pacman started, it was pointed squarely at the neighbors’ house. Ugh! But it wasn’t too long before the nebula emerged. The Dwarf’s auto-stacking did an okay job, but using Megastack to manually remove bad subs helped. Here’s the original:

Dwarf app showing output of 61 subs, 60 seconds, 60 gain, duo filter
And here it is after manually deleting bad subs:

Dwarf app showing output of 53 subs, 60 seconds, 60 gain, duo filter; much improved from the previous
Finally, here it is with StellarStudio “auto”:

The Pacman Nebula
The Heart Nebula started out okay, but again, the neighbors’ house clipped us right at the end. Since I was in the habit, I manually deleted bad subs and restacked. Original:

Dwarf app showing output of 230 subs, 60 seconds, 60 gain, duo filter
And here it is restacked:
