Re: Milky Way

Finally looking at my tests from last night and I have to correct myself. No noticeable difference in coma between 1.4 and 2.8 and 4. Significant difference in vignetting. But that is (somewhat) easily corrected for. Once Adobe gets lens profiles it should be totally solved.

FYI, My manual lens corrections (so far, I need to do some serious testing yet) are:

Distortion +19

Defringe

purple 6, 30/70

green 2 40/60

vignetting (at f/1.4) +46 and midpoint 9

vignetting (at f/2.8) +21 and midpoint 9
I can see minor trailing at 8 seconds, none at 4 seconds

If I have clear skies on my trip to Ireland (HAHAHAHAHA!) I'll stack 9 four second exposures at ISO 800 and f/1.4.  Being as it's Ireland in October, I don't see any point in bringing my tracker, the odds are not good
