10p 20260620 cschur

So how far does the dust trail extend on both sides of the comet?  This shot attempts to answer this question by shooting a fast lens for many hours on the comet from a dark sky site.  The field here is 12 degrees wide, so on the right (west) side it seems to extend around 5 degrees.  The eastern side is a bit more difficult due to extensive IFN however it is clearly much shorter, perhaps half the length.
