My little Dumbbell

This is the Dumbbell Nebula, otherwise known as M27. What you are looking at is the massive amounts of material being ejected from a dying star. As the star burns out its fuel it begins to cool and lose mass, collapsing and exploding. What a way to go!

Although it has the nickname "Dumbbell", I think it looks more like an "Apple Core". Hence, I am starting an international movement to have it re-named. If you want to support this movement send as much money as you can to me and I will make sure it is put to good use (in the name of science of course).

This image started out as a test: new focal reducer, new HA filter, new processing scheme, etc. I shot this target on two consecutive nights from my heavily light polluted home in Dallas (and with a full moon). The first night I shot RGB color with my Reducer Q, then the next night I shot HA (Hydrogen Alpha wavelength) without the Reducer Q. I registered and combined these data sets to yield the image you see here. I was really surprised by how much good data I got -- the HA filter REALLY helps enhance the RGB (and is impervious to light pollution).

Most folks use long focal lengths to get a lot closer to this target, but I was happy to keep it in this WIDE field. It is like a little colorful island in the abyss.

And stay tuned... I have a LOT of new images coming soon : )

Nice stuff. Again! The fact this massive nebula is sooo tiny in the frame of the picture adds to that "vast" feel of space.
