Imaging Comet 2I/Borisov = C/2019 Q4 (Borisov) on 2019 10 08 from MPC H06

There has been a good bit of buzz over a comet known as 2I/Borisov = C/2019 Q4 (Borisov). Given the fact that it is the second known interstellar object to make its way through our Solar System would explain much of this buzz. If there is buzz if the object is in range of the telescopes if there are open time slots, and the weather helps out, more often than not, I am going to give it a try.  With 2I/Borisov being low in the predawn sky, I had to wait for to be at an altitude at which the telescope could take the images.  I set up the plan to image 2I/Borisov when it was at an altitude of 27 degrees(minimum target altitude: for T11 is approx 20 degrees). I had the telescope started imaging about a half-hour before the end of full darkness. I had T11 take 15 - 60-second luminance BIN2 images.

Background 
Gennadiy Vladimirovich Borisov, a Russian amateur astronomer, has discovered the first known interstellar comet, 2I/Borisov. Discovered at MARGO (Gennadiy Borisov's observatory) in the Republic of Crimea on Aug 30, 2019. This object was reported to the Minor Planet Center as a "comet candidate" using the observer-assigned temporary designations gb00234. This object was posted to the NEOCP/PCCP, confirmation page, and observations poured in from around the World. On Sep 11, 2019, MPEC 2019-R106 : COMET C/2019 Q4 (Borisov) was issued, which stated the possibility and the need for more observations. MPEC 2019-S72 : 2I/Borisov = C/2019 Q4 (Borisov) was issued on Sep 24, 2019. This MPEC stated confirmation of its "hyperbolic orbit and interstellar origin" and "assigned the permanent interstellar designation 2I."

Confirmation Images of the COMET C/2018 K1 (Weiland)

On 2018 05 25 Henry Weiland an observer with ATLAS-MLO(Asteroid Terrestrial-impact Last Alert System ---Mauna Loa) reported a possible comet to the Minor Planet Center in Cambridge, Massachusetts, USA.  This possible comet was reported using the observer-assigned temporary designation "A1072Wf".  It was posted to the Possible Comet Confirmation Page(PCCP) and came to the attention of observer around the world. On 2018-05-26 I woke up, check iTelescope.net and saw that their facility in Siding Spring Observatory, AU was open. So had T30 started an imaging run of  60 - 60-second luminance BIN2 images and went out to eat breakfast. I got back made four stacks of 5 so can work around "stars that were in the way." I submitted my observations, as more observations came in and as the morning change to the afternoon, I saw my observations had poor residuals, so I did imaging run of  60 - 60-second luminance BIN2 images on T27.

Comet C/2015 V2 (JOHNSON) Look at You NOW.....

One of the cool things about observing comets and asteroids is one gets see how a comet's coma and  tail develops as they approach perihelion. when Comet C/2015 V2 (JOHNSON)  was on The Possible Comet Confirmation Page(PCCP) it was just small faint spot on CCD image now it is around magnitude 8 in range of a backyard telescope or nice set of binoculars.
