| Processing |
This image was processed entirely in Images Plus.
Calibration,
stacking, statistical filter applied to reduce noise before stretching.
Masked
stretching and split star processing
used to enhance the image. Masked noise reduction using a frequency
domain lowpass filter applied to the DSO layer and then it was
recombined with the star layer. Image binned 2 by 2. Final sharpening
applied. Since the 60Da has on sensor dark suppression, no darks were
used in the calibration. |
