OriginStack

Gallery

Every image here was stacked and processed entirely with OriginStack from the raw frames of a Celestron Origin, in backyard and rooftop sessions under heavily light-polluted skies (Bortle 7–9). No other software touched them. Select an image to open it at full size. To see the same sessions beside the stack the Origin saved itself, see the Origin vs OriginStack.
