M33- The Triangulum Spiral Galaxy
with 10" f/3.9 Astrograph
Uploaded 10/23/17

 
This
            is the deepest image so far that I have taken of this galaxy
            with the 10 inch astrograph. 3.5 hours of Hydrogen alpha data
            was combined with several hours of luminance and color data to
            create this image. I dont think its possible to do much better
            with this setup.
