I took some exposures of the California nebula NGC1499 a night ago with Nikon D600am (astromono), 65mm/6.5 scope and 12nm Ha filter.
Another image with less packed JPG:

I'm still looking for a person willing to image narrow band with this camera (24MP full frame monochrome with no IR/AA-filters) and share the data from southern hemisphere and other way around to you too!
Contact me if interested
