North American Nebula – NGC7000 in Ha
North American Mosaic
This is a large mosaic of NGC7000 that was done in a 2×2 framing and then stacked in Astro Pixel Processor to stitch together. This is a project that is building on several nights of data and this is only taken in Hydrogen Alpha filtering. This will eventually become the Green channel in an RGB mosaic part of a larger project. The detail is getting sharper and deeper.
