Processing a deep-sky image:
The following instructions include the subtraction of a dark frame, but this may be
regarded as optional.
1) Make sure the ‘Auto Contrast Stretch’ is switched off and load your image into
SXV_hmf_usb. Select ‘Merge’ and then ‘Subtract Dark Frame’. Pick the appropriate
dark frame and the software will then remove the dark signal from your image,
leaving it somewhat darker and slightly smoother than before.
