All three of these look spectacular even with a big and bright moon out and they are all great both for visual viewing as well as imaging. And here I am now, with clouds in Woodinville — beside a big bright moon. And I’d be imaging comet 103p/Hartley 2 anyway, so what else to do!? Play with processing old data!

Again with data from June 26th 2010, I diligently put some effort into determining exactly what the impact of barlowing would be on M2. Sort of like the M13 comparison, I thought this would be an interesting way to really see the difference.
In this comparison, the constants were a big, bright full moon, haze, the CPC 1100, Orion StarShoot Pro v2.0, and the f/6.3 reducer. Processing was done in MaximDL and I left the reducer on even with the barlows – generally a weird thing to do – simply More >
