Vixen ED 80 - 2 hours and 4 hours
click the images for
a larger file..
North to the right as I
had the camera in a vertical mode. the elephant trunk and surrounds.
A first try at this, found it
to be very dim... the top images is two hours (12x600s) and the
bottom 4 hours (24x600s).. I am still having trouble in my processing
at the bottom end, the final blacks tend to crash with a ragged
edge... Just technique I'm sure, still learning. The longer
exposure sure did bring the Ha up a lot... but my stacking seems
to have blown out the star colors and I lost the small
bright red spot at the end of the trunk.... was there a few passes
acquired, processed with
massive bad pixel removal, flat calibrated, de-mosaic, and stacked
using std. deviation in Nebulosity, no darks.
almost all post processing in Nebulosity: color correction, curves,
scaling, color scaling, levels.
additonal pass of curves and color in PSCS3 with a little NoiseNinja
before jpeg conversion.
