Horse Head Nebula, an annoying preview
Horse Head Nebula, Barnad 33 and IC 434, is a dark nebula in constellation Orion. Image is taken from "down under". In Australia this nebula has a higher elevation, than here at 65N.
Why annoying?
This image is a composition of 3 x 1200s H-alpha light. With this modest exposure time, image is far better, than I have managed ever taken up here with a longer integration time, that's annoying!
A false color H-alpha
We will shoot more data for this object in near future. LRGB and more H-a, maybe some O-III and S-II to see, if there is any.
The telescope and technical information:
16" RCOS ja Apogee U9000 camera.
LRGB combo.
H-alpha 3x1200s, Dark, Flat and bias calibrated.
Raw data is shared with "Team Finland"
Processing workflow:
Image acquisition, MaxiDL v4.xxx
Stacked and calibrated in CCDStack.
Deconvolution with a CCDSharp, 30 iterations added 50% to non convoluted data
Levels, curves and color combine in PS CS3.
