  1. Bravo, you’ve made six images in one day! If they were mine, I would have cherished them very much 🙂
    Thinking about “Pillars of Creations”, those great smokestacks, the enormousness of the formation, one can only feel thrilled and humbled…


  2. Thanks Kazia. Six images in one evening is about the maximum I think. My heart wants more quantity but my head is saying slow down and improve the quality – although I could never hope to match Hubble’s amazing image of the Pillars with my trusty 60D.
