I have some problems in solving image.
I start from a raw image (in particular it is a .cr2 file) and after a demosaicing procedure I obtain a png file. Then, I'd like to solve this png but my astrometry local version is not able to solve it.
This is my solve-field command line in a python script
'solve-field --dir ' + output_dir + ' --no-plots --new-fits ' + solved_file + ' --match none --crpix-center --rdls none --index-xyls none --overwrite --downsample 2 --tweak-order 3 --scale-low 0.1 --scale-high 180.0 --scale-units degwidth ' + input_file
output_dir is the output directory
solved_file is the filename of the solved image
input_file is the input image
The issue is that astrometry is able to solve the same image but in a jpg format (converted directly by the digital camera).
My questions are:
- does astrometry work with a .cr2 file?
- does astrometry work with a .tiff file?
I'd like to share my image, so maybe someone could work on it, but its size is 45Mb (too large).
How can I do?
