Nice report Michael. Loved your description of M83, further cements the fact that my skies are sub par
Ghost of Jupiter should take a fair bit of magnification owing to it's high surface brightness. Perhaps increasing the image size gave an illusion of blurryness, as opposed to a small tight image, when in fact you were still seeing the same amount of detail, if not more, but "spread out' rather than "tightly packed", if that makes sense lol
cheers
