Re: Neowise with Big Dipper and trees ...

Better. I do notice that the dust tail changed color, from white to yellowish. In one of your images (all nice, I should say) the dust tail is even reddish. From my own photo efforts on the comet (two of which I posted here before), it would seem the color of the dust tail especially depends on the elevation of the comet during the sub-exposures. The closer to the horizon, the redder it gets due to atmospheric extinction.
