Hi
With the full moon up and a sky so bright I used the Baader 7 Nm Ha filter on Eta Carina nebula.
4x10 mins ISO400 Baader 7 Nm Ha filter, Idas uv/ir filter, MPCC coma corrector, 10 inch f5.6 newtonian, Modded 350D camera, hand off axis guided. Total 40 mins exposure time.
Sky was so bright I could not see Eta Carina naked eye at all, it was faster to use the Argo Navis to find it. The night was warm and there was a heap of dark current noise in the images, I took 3 darks afterwards and in Iris made a master dark, subtracting that in Iris from the light images got rid of most of the noise. A flat and offsets were also done as usual.

Processed in a hurry before i go to bed, no other noise reduction done as yet.
