DDS stacking subs /and colour filters

[solarboy]

Hi guys 

I've just got into using a colour wheel RGB CLEAR and IR filters. 

I have an  atik 314L mono been using that for about year  with some success and last night I used the filters on the crescent nebula done 10 300 second subs darks bias and flats  and the same on each colour but not sure on how to load them into DDS. 

Any tips or advice would be much appreciated. 

Regards Solarboy.
