ic 434, the
horsehead in Orion - 4.5 hours
processed using only
Nebulosity (except final jpeg)
click image for 50% full size
27 ten-minute subs, started
as Orion was rising and continuing through dawn... This image
was calibrated with darks and flats and a warm pixel removal then
demosaiced and stacked using standard deviation in Nebulosity,
before balancing color, applying curves and levels, and some GreyCstoration
noise reduction.
converted to jpeg in Photoshop, no other processing. The flare
is from zeta Orionis and seems pretty hard to avoid. A bit of
cropping was needed since
Nebulosity doesn't have a gradient tool and the 350 has a persistant
edge brightening, some left on the right side... probably errant
heating...
