Does anyone use Photoshop to stack your light frames? I usually just use DSS but have been having problems with it lately. For one, it doesn't like the RAW files from my SONY DSLR and I have to convert those to another format before it will stack them. If you do use PS, what methods are you using? I stacked my eclipse HDR in PS and used the convert to smart object and then changed the stacking method and that produced good results but I'm not sure if that method is the best for DSOs. Any thoughts are appreciated.
