The beautiful Rosette Nebula resides in the constellation of Monoceros, adjacent to Orion in the winter skies. This particular image was the first I've taken using an OAG for guiding. With the Keller corrector, the space is tight, requiring a narrow OAG. The SX OAG fit the bill and worked well, once adjusted. This image was taken at my driveway in Orlando, Florida, under mag 3.7 skies.
