4 hours after I took the image posted earlier in this thread I tried again when the clouds opened a hole. I used 1x1 binning for 0.5" per pixel resolution. Clouds only opened long enough for a black and white shot. Boy has it changed in those 4 hours. Now there's a ring that was only hinted at in the earlier image and it is off center the opposite direction. This guy seems to be making symetrical outbursts. For some reason, when converted to JPEG the nucleus goes from a near point to a blob that runs down and to the right (southwest). There's a bright jet in that position on the 16 bit tiff. I can't seem to get the JPEG to work right. The compression in Photoshop seems not to understand comets and I'm due to hit the road in 20 mintues so no time to figure it out.
