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.

The interstellar comet 2I / Borisov imaged on October 4, 2019 just when passed to an angular distance of only 15 arcminutes from barred spiral galaxy NGC 2903 in constellation Leo. One month after be discovered brightness of comet keeps around magnitude 17 and with a small tail, although is not perceived in this image beacuse its short exposure time.
