New target from the Australian Sky, M8
M8, the "Lagoon nebula" in Constellation Sagittarius.
New project, from Northern galactic remote telescope in Australia, has been started.
The Lagoon nebula, M8, in ionized Hydrogen light, H-alpha.
The telescope and technical information:
16" RCOS ja Apogee U9000 camera.
LRGB combo.
H-alpha 4x1200s, Dark and Flat calibrated.
Raw data is shared with Petri Kehusmaa and J-P Metsavainio
Processing workflow:
Image acquisition, MaxiDL v4.xxx
Stacked and calibrated in CCDStack.
Deconvolution with a CCDSharp, 30 iterations
Levels, curves and color combine in PS CS3.

M16, reprocessed
M16, the "Eagle nebula"
Close up.
I did this one again, since I carried away with processing at previous version!
"Less is more" as usually.
I haven't used to process so good data, than the Northern Galactic members telescope delivers.

Original Blog post here, processing looks little heavy handed:
NGC 4945, Finalized
NGC 4945, edge on spiral Galaxy in constellation Centaurus.
I was able to finalize this version, since I now have all the needed calibration images, Dark, Bias and Flat frames. This beautiful, large, edge on galaxy is overlooked, since there is two showpieces at neighborhood, M83 and the Centaurus A.
