M16 - Eagle Nebula
About The Image
Capturing the data on this night was extremely challenging. This was the first time imaging since the rebuild of the RASA 8 triplets.
I had alignment issues with all 3 astrographs, tilt problems so stars aren't perfect and power issues but I managed throughout the night to capture some data to put together the image you see.
More Hydrogen Alpha and Oxygen III data would be very welcomed.
