Description

M17 taken during the Oregon Star Party this year.  I had some problems with images taken in the southerly direction, especially this one.  I had to discard about half of the subs due to poor quality.  These were all taken within about 45 minutes of the meridian, so I am assuming that one of the RV's south of me was giving off a 'heat plume' that disrupted the light, making the images look 'soft', but I don't know for sure.
