The Horsehead Nebula in Orion
 with 10" f/3.9 Astrograph
Uploaded 2/7/16

 
This
            is the final test image before using the 10 inch full time for
            imaging deep sky and comets. Seeing was still quite poor, however
            the integration and technique for flats and darks is now complete.
            This image consists of 15 minutes of color data infused with
            30 minutes of Halpha data taken with a 3nm bandwidth interference
            filter.
