All files should be uploaded to the HOYS server in FITS format.
It can be useful – though not essential – to name your files using the target number and name, exposure time and filter used. For example
__.fits
Within the FITS header you should store the following information:
cumulative exposure time (the total of all stacked image exposures)
date/time of the sequence mid-point (or start in case of short – a few minutes – exposures)
filter used in a format recognised by the software
Again this is not essential as you will be asked for this during processing but it is helpful to speed up and automate the processing.
