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."
