NGC7000 LHaSIIOIII SM


NGC7000 LHaSIIOIII SM

My first real attempt at narrow band images. This is the core of the North American Nebula NGC7000. There are still many issues with the image. My flats just failed completely and I need to figure out what went wrong. Also my william optics flattener IV would not reach focus with the adapters that I had and the edge of field stars are elongated. Regardless, this is my first real image.
