has finally gotten high enough in the morning sky to see it with
the 12.5" Newtonian in the backyard observatory! While still
only 25 degrees up, the 5th magnitude object shows a remarkable
level of tail development consisting of a broad fan, and a side
fan of material that is not quite sun pointing. There seems to
be no trace of blues or greens here, indication of an exclusively
dusty object with very little ion tail activity.
This shot was produced
by taking 20 minutes of autoguided luminance data, followed by
2 minute RGB shots. The RGB data was combined in Photoshop layered
right on the star trails - 10 separate copies. Then combined
with "Lighten". This was then used as the final color
data for the trailed L data, which is tracked on the comets head.
this is the only way we can use a single set to color an image
that is trailed as it follows the comets motion.
