Revision as of 19:36, 8 October 2014
Some processing results made with Siril
The moon, 19 images manually aligned, unsharp mask, white balance, crop.
A star trail image:
- Pre-processing with darks and offsets, no alignment required, pixel maximum stacking, background extraction, subtraction of green noise, enhancement of saturation.
(The image above has been reduced and ocnverted to png format)
M 33 (©V. Cohas):
- Pre-processing with darks, offsets and flats, sum stacking, color calibration, subtraction of green noise, enhancement of saturation.
NGC 7635 (©S. Fleury Billot):
- Pre-processing with darks, offsets and flats, sum stacking.
