with 10" f/3.9 Astrograph

Here
            is an image I took per a request from a magazine for an article
            they were working on. The globular cluster was low in the south
            east at 5am, however seeing was great that morning so the image
            came out fairly well. M68 which is a small globular cluster in
            Hydra was really too small of a target with the 10 inch, so for
            this image I cropped the orignal shot to the inner 50%. Blue
            and gold supergiant stars can be seen in this object along with
            a few background galaxies.
