I have read about astrophotographers stacking images to achieve a superior image and there are several pieces of software out there labeled for that specific task. The one that comes to mind was produced by Meade and called Autostar Suite. Is this the same thing as HDR? ❓
Nah, what astronomers do is more like lowering your ISO and taking a longer exposure.
Actually, you’re both correct. Something along the lines of HDR is performed by astronomers, having many exposures at varying exposure lengths then combining the images together in PP. They do this to prevent having blown highlights – much like ordinary HDR.
