Order Notes

This is a re-processing of an image originally captured in September of 2012.  That version was combined with a second frame to form the image of the Heart Nebula in natural color (see Heart Nebula).  While the earlier version is close to natural color (pretty much all red), this one uses false color to bring out more detail, separating the H-alpha, O-3, and S-2 regions.

The Heart is an emission nebula in the constellation Cassiopeia and about 7,500 light years from Earth. It does look like a heart, sort of. I suspect that the neighboring Soul Nebula (also about 7,500 light years distant) was named just to satisfy the urge to put “Heart” and “Soul” together.

Scope: AT111EDT at f/5.6
Mount: AP Mach1
Camera: QSI 583 at –20C
Exposure: H-a/OIII/SII, 8 hrs total


About Greg Marshall

I am a retired electronics engineer and after a few months of enjoying my leisure I began to miss doing product development. My astronomy hobby always needed new solutions to unique problems, so I decided that whenever I came up with a good solution I would try to make it available to others.
