How many times have you had to open a FITS file
just to inspect the header for some of these items?
This allows you to import the Luminance Mask FITS file
you had saved, and apply it to your image.
Save the file as an IEEE Float uncompressed FITS file
to avoid clipping any of the signal.
Simply save the result as a 16-bit FITS file
, and repeat the same process to combine your dark frames by selecting the Process/Create Calibration Master/make master Dark.
During the observing season of 2008 approximately 8 000 V filter and 10 000 B filter images were captured to fits files
Note that the RAW/FITS DDP Settings apply to RAW and FITS files
only; Auto White Balance will not work with JPEG images.
Because 16-bit FITS files
will always appear dark with only a few stars before you apply any contrast enhancement, you should perform an initial STF AutoStretch to display faint areas.
Previously, traditional graphics programs such as Adobe Photoshop could not open FITS files
are the only exception, requiring 16-bit grayscale images.
It also contains good explanations of the many image formats available, particularly the astronomical-standard FITS files
Their freeware Avis FITS Viewer has modest image-manipulation capabilities but eclipses other, more powerful programs by being able to import 8- and 16-bit FITS files
-- the world's standard format for exchanging astronomical data -- as well as numerous other image formats, such as those from SBIG, HiSIS, and Starlight Xpress cameras, and then save them in TIFF, Targa, JPEG, and BMP formats.
