The night,
without the noise.
Claron stacks the frames from a night on a fixed tripod into one clean picture: stars sharp to the corners, the foreground as you shot it.

One frame is mostly noise.
Fifteen seconds at ISO 6400 is a compromise, and it looks like one. Stacking twenty frames averages most of the noise away. But on a fixed tripod the sky turns and the ground stays put, so the two cannot be stacked the same way.
Sky and ground, decided pixel by pixel.
Claron aligns the sky to its stars, with one model of the lens for every frame, so an ultra-wide lines up all the way to the corners. The ground stays where it was shot. Where the two meet, the frames themselves say which is which, so a ridge keeps its edge without a halo and the sky above it gets no dark band. Measured on twenty frames at 24mm:
- 3.77×
- less noise in the sky than in a single frame
- 0.27px
- alignment error across the frame, 0.22px in the corners
See it before you commit.
Draw a box anywhere on the frame and that part is stacked in seconds, exactly as the export will be. Zoom in on the ridge, paint over anything the mask got wrong, and compare before and after side by side. Every frame shows its stars, their size, the sky's brightness and how well it aligned, so the one with cloud or shake is a click away from being left out.
It lands where you already work.
Out comes a Linear DNG that Lightroom develops like the raw it came from, white balance and colour still adjustable, or a 16-bit TIFF in sRGB, Adobe RGB or linear. Darks, flats and a long exposure for the foreground go in the same stack, and none of it leaves your Mac.
