The Heart Nebula (IC 1805) is an emission nebula located 7,500 light-years from Earth in the constellation Cassiopeia.

At the center of the nebula lies a small group of stars emitting intense red radiation. This star cluster, known as Melotte 15, contains several bright stars that are 50 times more massive than the Sun.

Data acquired with a Takahashi 106ED telescope at the Telescope.live observatory.

Yes, that seems to be the case. It's my first time working with such a dataset, where the images were taken on different days, so that's quite possible.

It would have been a great photo if not for the "traffic light" effect on the stars.
And it could easily be fixed!

How do you do that? Is there somewhere to read about it?

Later, closer to night, I'll write in a private message on the Astroforum.
