| Image Processing |
* Images Plus 2.75 - Calibration, Bayer Interpolate, Grading, Alignment, Sigma Clipped Average Combine, mild DDP, 2 iterations of R/L deconvolution. * Adobe CS - Levels, Curves, Masks, Sharpening, RGB balance, Cropping, JPEG conversion The color image is a Ha+RGB composite. The Ha data was mixed 75% with the R channel then recombined with the GB data. This brought out the faint outer nebula structure and details that was otherwise not seen in the color data. |
