in the morning sky

 Now 1.5 magnitude
            and fading into the Sunrise, I was able to for the last time
            to get the comet this morning which was burried in thick forest
            fire smoke only a few degrees up in the east. This was the first
            morning in weeks to see it with out clouds interfering as well.
            The resulting raw frames, each 15 seconds in duration were deep
            redish yellow in hue, virtually no blue or green was present.
            By adding the blues back in, I was able to recover most of the
            original colors, and stopped when the comet turned white. Extremely
            challening target for sure! The 8 inch RASA was set up on the
            second floor balcony on the east side of our house, and only
            a very narrow window in the tree tops would allow looking so
            low in the direction of the comet.

            
We now await its
            swing behind the Sun, to re emerge in the western evening sky
            brighter than ever. Since we have absolutely no view of the west
            from our house, I will have to travel each night to a distant
            location to image it.
