  1. Comet C/2017 T2 (PANSTARRS) imaged on 2019 November 30 through IAC-80 Telescope in Teide Observatory (IAC). Shows a coma with 1.5 arcminutes of angular size (some 110 000 km in absolute size) and a dust tail which get out field whith at least 11 arcminutes lenght. The attached image, at maximum resolution and stacked on the comet, don't shows any structure in the inner coma. At down-left I have included an Earth image at same scale of the comet.

  2. Comet 260P/McNaught imaged on 2019 November 29 through IAC-80 Telescope in Teide Observatory (IAC). Shows a coma some smaller than 1 arcminute of angular size (30 000 km in absolute size) and a dust tail in fan shape. This image, at maximum resolution and stacked on the comet, shows in detail the inner coma where are perceived jets of material emerging from nucleus. I have included an Earth image at same scale of the comet: Data and link to image: https://cometografia.es/260p-mcnaught-20191129/
  3. Image of comet 260P/McNaught, taken on 2019 November 23 when begun to weakening with a brightness of magnitude 12. From its whitish coma with 1 arcminute of angular size departs its dust tail which has turned opening in fan shape toward south. Post and image link: https://cometografia.es/260p-mcnaught-20191123/
  4. My last image of comet C/2018 W2 (Africano) taken on 2019 November 17, when it had moving away until 1.8 AU from Sun and Earth its brightness had dropped to a magnitude near 13 with a very faint green coma some 3 arcminutes of angular size and a weak dust tail with 5 arcminutes lenght. Data and link to image: https://cometografia.es/2018w2-africano-20191117/
  5. Comet C/2018 W2 (Africano) imaged on 2019 October 26, although meteorology wasn't good still can be perceived its greenish coma and short dust tail on a field of Piscis Austrinus plenty of small galaxies. Comet has a brightness at magnitude 11 whilst the two brightest stars has magnitude 8.2 (center) and 8.4 (left). Data and link to image: https://cometografia.es/2018w2-africano-20191026/
  6. After its approaching on September 2019 when reached magnitude 8.5, comet C/2018 W2 (Africano) has speedly dropped in brightness until magnitude 11 in this image, only with luminance filter, taken on October 24, 2019. Around its more compact coma still can be see a faint envelope with near 6 arcminutes of angular size and a dust tail with some 11 arcminutes lenght.

  7. The interstellar comet 2I/Borisov imaged on 2019 October 12 by Hubble Space Telescope. Given public availability of raw shots I decided to download and process them in my way, mainly to leave out the false color as we have seen them published and to study PixInsight workflow for pre-process Hubble Telescope raw images. This very high resolution image has a field of only 1 arcsecond square. Data and link to image: https://cometografia.es/2i-borisov-20191012/
  8. Interstellar comet 2I/Borisov on October 10, 2019. With a brightness around magnitude 16 shows a fairly condensed coma of 0.5 arcminutes and a tail toward northeast with at least 1 arcminute. Data and link to image: https://cometografia.es/2i-borisov-20191010/
  9. 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. Data and link to image: https://cometografia.es/2i-borisov-20191004/
  10. I have uploaded images instead link them, I think you can see now. Thanks.
  11. Comet 260P/McNaught on 2019 October 12 at its maximum brightness around magnitude 11. Its coma measures something less than 1 arcminute of angular size, observing two jets getting out that are immersed into its dust tail which extends about 5 arcminutes lenght. Post and image link: https://cometografia.es/260p-mcnaught-20191012/
  12. Comet C/2018 N2 (ASASSN) imaged on November 29, 2019 through IAC-80 telescope in Teide Observatory (IAC). With a coma 1 arcminute diameter (110 000 km absolut size) and a dust tail with 6.5 arcminutes lenght. Even though the most remarkable is the high detail inside coma of a comet with magnitude 11.5, only possible by means of a telescope like this. Data and link to image: https://cometografia.es/2018n2-asassn-20191129/
  13. Comet C/2018 N2 (ASASSN) on October 11, 2019 near its maximum brightness with magnitude 11 shows a coma of 1.25' angular size with a dust tail 10' lenght. The bright blue star is HD 9298 with magnitude 6.4 into Triangulum constellation. Data and link to image: https://cometografia.es/2018n2-asassn-20191011/
  14. Wide field image of comet C/2019 W2 (Africano) taken on September 27, 2019, are 4 x 2.5 degrees centered in a side of Pegasus square. With a brightness in magnitude 9 comet shows a nice green coma with 12 arcminutes and a slightly curved dust tail with half degree lenght.
