NGC 7000 North America Mosaic
NGC 7000 North America Mosaic
Started playing around with more mosaic images since the RASA 11 takes such little time to capture. This was a 2×2 panel mosaic in Ha, Oiii, Sii filters and stacked in AstroPixelProcessor, then detailed in PixInsight and PS. Using the Photon Cage gives really flat tilt-free imaging and has been dong mosaics much better than I was seeing, so pretty happy with that.
