  1. A comet with binoculars could be a luxury nowadays. Thanks Dave.
  2. Comet C/2018 W2 (Africano) is the next comet relatively bright which could reach visual magnitude near 8.5 this September. In this image taken on July 7, 2019 has a brightness in magnitude 12 approximately, and a greenish coma with an angular size of 1.5' and a strong condensation. Data and image at better quality: http://cometografia.es/2018w2-africano-20190707/ --------------------------------------------------------------------------------------------------------------------- Comet C/2018 W2 (Africano) on July 9th 2019, showing a coma with 3' of angular size. This comet seems having more activity since some days ago and could be observable with binoculars on September. Data and image at better quality: http://cometografia.es/2018w2-africano-20190709/
  3. On 29 April 2019 Jaroslaw Grzegorzek, a polish amateur astronomer, discovered a supernova into galaxy Messier 100 when this had a brightness at magnitude of 16.5. Five days after I took this image centered in this magnitude 9.5 spiral galaxy at 55 million light-years in constellation Coma Berenices and discoverd by Pierre Méchain on 178. The supernova is located relative near of core galaxy, 15 arcminutes toward Northeast, and its spectrum indicates that its brightness is being fairly reduced because dust clouds of galaxy. Telescope GSO 8" N f/3.8. Camera Atik 383L+. Exposure 2.7 hr. (L=29x240 bin1 + RGB=8x120 bin2). From Hoya Redonda, Valencia (Spain). Processed with PixInsight. http://cometografia.es/sn2019ehk-m100-20190505/
  4. Comet 46P/Wirtanen on March 10th 2019, while moves away keep going down in brightness until magnitude 10, and its coma decreasing in angular size until some 3 arcminutes. Half dozen small galaxies also can be observed in this field into Ursa Major. Telescope GSO 8" N f/3.8. Camera Atik 383L+. 21 min. total exposure. From Vallés, Valencia (Spain). http://cometografia.es/46p-wirtanen-20190310/
  5. More images about comet C/2018 Y1 (Iwamoto): Comet C/2018 Y1 (Iwamoto) photographed on February 26th 2019. Since my previous image two weeks before when was at its maximum with magnitude 6, comet brightness has dropped until magnitude 7.5, decreasing at same time its coma angular size from 20 to 12 arcminutes. Tail also has faded quite, very faint and with only 10 arcminutes lenght toward East (to left). Telescope GSO 8" N f/3.8. Camera Atik 383L+. 167 min. total exposure. From Vallés, Valencia (Spain). http://cometografia.es/2018y1-iwamoto-20190226/ Going away from inner Solar System the comet C/1018 Y1 (Iwamoto) has in this image taken on March 2nd 2019 a brightness of magnitude 8.5 and a coma angular size of 12 arcminutes with a intense turquoise color, contrasting with this zone plenty of red emission clouds into Auriga constellation, in which highlights in upper part of image the Flaming Star Nebula (Sharpless 230) and in down part the Tadpoles Nebula (Sharpless 236). Telescope Takahashi FSQ-106ED f/5.0. Camera SBIG STL-11000M. 21 min. total exposure. From Mayhill, New Mexico (USA). http://cometografia.es/2018y1-iwamoto-20190302/ Comet C/2018 Y1 (Iwamoto) on March 10th 2019, losing brightness until magnitude 8.5, shows a greenish coma with some 7 arcminutes of angular size and gradual condensation. Still has a short trace of tail. Telescope GSO 8" N f/3.8. Camera Atik 383L+. 27 min. total exposure. From Vallés, Valencia (Spain). http://cometografia.es/2018y1-iwamoto-20190310/
  6. Comet 46P/Wirtanen photographed on February 10th 2019 when passing near bright star Theta Ursae Majoris of magnitude 3. After its maximum with magnitude 4 on past December, here the comet has dropped until magnitude 8 with a greenish coma which also has reduced condensation and angular size to 10 arcminutes. Telescope GSO 8" N f/3.8. Camera Atik 383L+. L=8x120s bin1 + RGB=3x60s bin2. From Vallés, Valencia (Spain). http://cometografia.es/46p-wirtanen-20190210/
  7. Comet C/2018 Y1 Iwamoto on February 10th 2019 , three days after its perihelion and three days before ist maximum approaching to Earth. Its ionic tail is faintly visible toward West (to right) in this image, at same time is possible to see a dust tail toeard Southeast (to down-left) only during these days in which our planet cross the orbital plane of comet. The Iwamoto also reached those days its maximum brightness with a magnitude near 6.5 and a coma with angular size of 20'. The brightest star into field is Chi Leonis with magnitude 4.6. Telescope GSO 8" N f/3.8. Camera Atik 383L+. 68 min. total exposure. From Vallés, Valencia (Spain). Totally myself http://cometografia.es/2018y1-iwamoto-20190210/
  8. This image has only 6 minutes of luminance and is guided on stars, sufficient to no evidence comet trail.
  9. Comet C/2018 Y1 Iwamoto photographed on January 18, 2019 in a image one square degree, shows here a greenish coma of 8' angular size and a small tail 5' long. The comet have here a brightness near magnitude 9.5 and could be seen through binoculars on next February month. Telescope Planewave 20" CDK f/4.4. Camera FLI-PL09000. 9 min. total exposure. Remotely from Siding Spring, NSW (Australia). http://cometografia.es/2018y1-iwamoto-20190118/
  10. Comet 46P/Wirtanen photographed early morning on January 6th 2019. Its coma has angular diameter half degree in this image with elongated shape to southwest toward seems there are some tail. Between constellations Lynx and Ursa Major on a field of faint galaxies, the comet has near magnitude 6. Telescope GSO 8" N f/3.8. Camera Atik 383L+. 37 min. total exposure. From Vallés, Valencia (Spain). http://cometografia.es/46p-wirtanen-20190106/
  11. Comet 64P/Swift-Gehrels imaged on January 5th 2019, three days after a increasing of activity since which has developed a short tail. The green coma has an angular size of 8' and its brightness is near magnitude 8.5. The brightest blue star is 55 Arietis with magnitude 5.7. Telescope GSO 8" N f/3.8. Camera Atik 383L+. 26 min. total exposure. From Vallés, Valencia (Spain). http://cometografia.es/64p-swift-gehrels-20190105/
  12. Nearly at zenith, comet 46P Wirtanen can be seen catched between vanes of spider which holds the camera situated on focus of Telescope TAR1 in Teide Observatory, meanwhile is photographed. This panorama includes the Pleiades star cluster near center of image, and a little beyond the red trace of California Nebula. At down, Hyades open star cluster, including the bright star Aldebaran, shape central part of constellation Taurus. Labeled version: Lens Samyang 16 mm. f/2.0. Camera Canon EOS 100D. 90 sec. exposure at ISO 3200 (one shot). From Teide Observatory, Canary Islands (Spain). http://cometografia.es/46p-wirtanen-atrapando-20181210/
  13. Comet 46P/Wirtanen shows in this wide field image taken on December 10th 2018 a huge coma with 1.5 degrees of angular size, three times the size of Moon seen from Earth. With a global integrated brightness at least in magnitude 4, as reference the brightest star to right is 94 Ceti with magnitude 5. The inner coma contrasts exhibing a whitish color, also the faint tail toward northeast (to down-left). The field appears scattered with tiny galaxies, some visible through comet atmosphere. Telescope Takahashi FSQ-106ED f/5.0. Camera SBIG STL-11000M. 15 min. total exposure. Remotely from Mayhill, New Mexico (USA). http://cometografia.es/46p-wirtanen-20181210/
