C/2019 Q4 (Borisov) @ September 12,2019 11:08 UT

Recent discovered interstellar comet C/2019 Q4 (Borisov) imaged in color on September 12, 2019 at 3.36 AU from Sun its brightness is magnitude 17 showing in this image a size with only 18 arcseconds in which can be observed elongated shaped toward northwest. Analyzing color channel shots seems to me that comet shines more in blue, but I can not confirm it, have to wait some days to achieve more detail.

Acquisition details:
Telescope Planewave 17" CDK f/4.5
Camera FLI PL6303E
Exposure 9 min. (L=3x120 bin2 + RGB=1x60 bin2)
From Mayhill, New Mexico (USA).
