North to the right as I
had the camera in a vertical mode. Not enough field to get both
M8 and M20, so just gave M8 a try with
a gibbous moon only about 20 degrees away. There are some streaks
that I think are an artifact of the chip, but
might be noise artifacts. They occur in both the dark fram compensated
and the bad pixel removed versions.
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.
A run of Ninja in PSCS3 to try to reduce the streaking before
jpeg conversion.
