This is early testing of my Nikon Z5 Astro modified camera. I had my camera modified to allow the reds to pass through to the sensor without any blocking of the hydrogen alpha wavelengths. Allowing for much higher sensitivity and thus shorter, less noisy exposures. Cameras are designed for normal (visible) light photography. They are set up to reduced the red alpha channel. In the night sky many Nebula's have hydrogen alpha wavelengths which a non-modified camera would not show the nebula's true color. To reduce noise I stacked 11 photos in a program called Sequator.
