Image notes
|
The above
is a combination of a NB and 25 percent of a RRGB image.
All of the individual channels were deconvolved to match
stellar profiles prior to color combining. The NB
color mapped image used a synthetic Lum channel that was created
from the Ha, OIII and SII in CCDStack 2. The Red
channel was used as the Lum to create the RRGB image.
Final
processing was done in CS4.
