I love this particular section of the Rosette Nebula. I have managed to increase the magnification and resolution by not using a focal reducer with the AstroPhysics 130mm refractor, and replacing it with a field flattener. For the price of a slower speed and reduced field of view, precise higher resolution images are easier to attain. In this configuration the speed is reduced to f6.3 with the field flattener versus about F5 with the reducer. This stacked image is a combination of 15 thirty minute exposures for a total imaging time of 7.5 hours in H-Alpha.
