The Crescent Nebula
This object is special to me. It was an image of the Crescent Nebula that a guy from the Netherlands had posted. In the description I read that he used
a stock DSLR for color and a mono converted DSLR for Ha and combined the data. In the moment when I read this it was clear to me: this is the way to go!
Then followed a long struggle with a poorly converted old Canon 40D that I never really got working, a long search for a better mono camera and as I
could not find one another search for someone who does mono conversions. Finally I got exactly the same camera I already own as a mono version.
Finally after more than a year the loop is closed: I made my OSC-Ha combination of the Crescent Nebula.
