At my observatory, Looking Glass Observatory,
Buena Vista, GA. I was using a C14 @f/22 with a Lumenera SkyNyx 2-0 monochrome camera.
I imaged Jupiter last night (07-31-09) and noticed even more elongation of the impact area. The seeing was only average. I also noticed a darker area near the GRS that I hadn't noticed before. I don't know if it is significant. I submitted one I took on 6-17-09 for comparison (it was taken under excellent conditions!)
