I have some time available in my life right now that allows me to get out and find dark skies. I made my way up to the upper peninsula of Michigan last weekend where I was treated to some great, great skies. That combination of new moon + new moon on other side of the earth + clear skies + low wind + open horizons = ... man, so awesome. Plus I got to see the ISS fly by for the third time this week!

These are with an unmodded 6D and the Canon 200mm 2.8 II on the iOptron Skytracker. I believe I ended up stacking sixty-two 60 second exposures. I only took 3 darks because my battery died! I had to coax the 3 shots out of the camera by removing the battery and warming it up for a few minutes in my armpit before attempting another shot. I managed 4 or 5 additional shots this way!

This orientation is how it appeared to me from my spot on earth. It's still somewhat low on the horizon and I suppose that's what contributed to my gradient.

Yesterday I posted a slightly different version in the You don't need a Telescope thread, but took another go at the editing. I spent a little more time working with the gradient removal and was able to get quite a bit more detail and color:

For reference, here's that gradient with the image straight out of Nebulosity where it was stacked and stretched prior to Photoshop:

Thanks for looking.

Excellent captures there . That's a nice lens your using . Within this area there is one large GC M4 but there is several small GC that may look like big stars to you but they are not . Only thing is unless your looking through a scope you'll never be able to see the detail in each GC :( . There is at least 3 and possibly 4 small GC in your shot outside of M4.

If you promise not to tell anyone about my plan (As they may steal the idea and thus my profits) I am thinking of making a new Reflective Telescope, very simple, cheap but highly effective with only one single mirror at the bottom end and absolutely no secondary mirror or lens involved. Then incorporating a high resolution sensor, say 2MP or better (Probably about $100) at the primary focus. With a touch of simple board, image of telescope will appear on any larger screen of your hi rez monitor attached via one of the simple common todays video ports and through a simple in house cpu additive image by user's preferred timing, you can have the best image of night right at your very simple and cheap telescope that needs no collimation, heavy knowledge of know how etc.
Best of all it is not a Newtonian, Cassegrain, Gregorian, Herschelian telescope. And I feel Samsenian fits very well with the nomenclature of the telescope.
Again make sure no one steal the idea from me and let it be recorded that it is all mine!:)
