Messier 83 known as the Southern Pinwheel, is located 15 million light-years away from Earth in the constellation Hydra. It was discovered in 1752 by the French astronomer Nicolas Louis de Lacaille. With an apparent magnitude of 7.5, M83 is one of the brightest spiral galaxies in the night sky.
The pic is remake of my data collected in last February and March. Ha data is a mixture of both T1 and T2, with a total exp of 3.7 hours.
With the help of drizzle integration and BlurXTerminator, star cluster within the galaxy can be revealed clearly.
The lum channel was first drizzled before decon and then 0.5x resampled to fit with RGB channels.
Besides, it seems that BXT works better in a 2x Drizzled MasterLUM than a ordinary one. I also notice some grass-shape H-α signals on 7 o' clock. Does it indicate a burst of H-α, like the grass-shape OIII signal recent discovered in M31?
