I don't have DSS to try but up till now have had no problem with PixInsight.
By unuseable I mean the files, when taken into PI, are fine as shown by the above image, but if I callabrate the images before any other processing then they go dark with a few bright stars showing, and STF function will not change them to be able to see what signal is there. This issue makes them unuseable as STF is needed to see what happens during other processing steps before HT is done.
Any tips greatly appreciated.
I quite like Prism 10 for telescope, focus, guiding, imager, plate solving and observatory control (when I can eventually add a dome or motor for ror), I don't plan on using the processing capabilities as I like PI for that.
Using a single software package greatly simplifies things in my opinion, as opposed to using multiple packages theat need to play nice together.

Hi Shane,
OK - I have a different method.
I stack with DSS - output as 32 bit FITS files and I think it's as integers not floating point.
I then stretch them with NASA FITS Liberator & save them as 16 bit TIFFS
so that they can be processed in Photoshop and Fitswork4.
There is probably an advantage in keeping the data in 32 bit format using PI but
as the KAF8300 camera I use has only 16 bits then 32 bits is probably going overboard
for negligible gain.
I advise you to try that method as it's actually quite easy -
if you have Photoshop open then NASA FITS Liberator will
put each LRGB file straight on to the screen ready to process.
NASA FITS Liberator also gives you many different mathematical stretching algorithms.
I suppose PI does the same?
cheers
Allan
