If he behaves like comets of the solar system he should be 14-15 mag in november and december. Visually, you will need 12-14 " for him

Great images, especially the animation.cool.gif Please correct me if I'm wrong but Borisov has yet to be officially confirmed as interstellar?

The Weekly Information about Bright Comets (2019 Sept. 14: North) website has a page on this comet

http://www.aerith.ne...9Q4/2019Q4.html
 

 

that shows this magnitude chart showing the projected magnitude peaks in December 2019 and is estimated to be just below 15th magnitude, which puts it out of reach of most amateur telescopes.

Here are two images taken at the Slooh Remote Observatory of 2I/Borisov on 10/12/19 with the Slooh Canary One Widefield Scope. They clearly show the comets movement to the southeast.

I imaged Borisov last night with 10cm refractor.
Two 5 min luminance exposures clearly showed it and its movement.

Hello

 

The comet does not get much brighter and is now around 17m0, but the tail is now longer. He is also further away from the sun. On October 26, he was near Regulus and the Leo Dwarf galaxy

...and just a try from Dolni Bousov / Czech republic (enormous stretching had to be used in order the comet to become visible at all). N200/1000 + Atik 314L+, 420s exposures used. My try was about whether or not I can capture the comet from my light polluted backyard (small town) it is not about quality. Thus I am sorry for it...
