This observation was taken through a 16" binocular under truely dark skies.Moving on to the dumbbell nebula, it was quite fortuitous that this object was low to the horizon and I needed to be seated before looking through the eyepiece, as if I was standing on a ladder I would surely have fallen off backwards with amazement. In the past I have only seen the dumbbell nebula as a blurry apple core shaped object that was a dim and relatively indistinct object. Changing from 12 inch to 16 inches of aperture has made a huge difference to what is visible in this nebula. Now not only the core but the fainter outside edge is of the nebula where easily visible, with binocular version one of the huge benefits that you get is not only the increase in contrast but more importantly greatly enhanced shaped recognition. We were able to see texture in the surface of the core, several notches and irregularities were easily visible on one edge of the nebula. Today after going back and looking at a photograph of the dumbbell nebula afforded little improvement on what I was able to see with my own eyes.
