Mosaic of the North America and Pelican nebulae with a standard Seestar S30

Using a standard Seestar S30; 3 hours worth of 30s exposures were captured and live-stacked as a mosaic of the North America and the Pelican nebulae. The live-stacked Fits file was processed in PixInsight, GraXpert, Gimp3 and SetiAstroSuitePro.

Presented here as a linked channels image, an unlinked channels image and a blended image.

The live-stacked Fits file was used because during the stacking, star-correction is applied and the resulting stacked mosaic image is a 16 bit image that is already plate-solved and ready for further processing.
Of course a mosaic takes time, but the mosaic captured here was framed to its maximum size. Three hours was adequate to produce an acceptable image from a low cost standard Seestar S30.
