Already tried normal stars, galaxies, open clusters, so now I need to try some nebula. Orion nebula is supposed to be a easy target but now it is not currently in the night sky. Some other Nebulae, like Ring Nebula, is too small for me. I noticed that 25 arcmin (Pin-Wheel Galaxy) of size is kind of a limit for faint structures like nebulae and galaxies. I got a 7 arcmin on the M28 cluster. But clusters are easier to spot I believe. So I went for something big out of my balcony, the 60 arcmin Heart Nebula.

For my disappointment, I could not see any nebula in here. Even after stacking and post processing. I can only see a bit of it in the lower part of the image, a bit to the left, a small fog in there, it is part of the lower part of the heart shape of the nebula. I can see also a weird reddish(?) color all around that could be just noise in the image.

Gonna need to try longer and better exposures on Nebulae.
