continues the approach of Comet 46P Wirtanen to its perihelion and to the Earth. here a photo of December 8 when it is 13.5 million km from the Earth. The magnitude is around 4.8mag while the coma exceeds 60 'in diameter , the tail of ions can be seen little, because it is prospectively behind the ...

this is an interesting comet,46P Wirtanen, in this passage it will be very close to the Earth and it is expected a magnitude, a December, inferior to the 4 ^ magnitude , at the bottom there is his current measure af (rho) which in 10 days has increased by 30% link for high res, https://www.astrobin...

the "puff" that you see in N-O I think it is a remnant of the outburst a few days ago

Rolando Ligustri : Messier Album At the end of 1800 the astronomer Messier cataloged objects in the Sky to not confuse them with the comets he was looking for. I wanted to enclose them in a single album made using modern photographic techniques, but at the amateur level. hi reg image : https://www....

Comet 45P (H-M-P) near the galaxies Ngc 4656 and Ngc 4631. are weakening, but also notice a slight change in the morphology of the coma. https://get.google.com/albumarchive/107386404051271210368/album/AF1QipMLhUxCXG5sX0-_0Pc-aOoK5grfph5qW4hXLGN5/AF1QipMFYBOVvsifbBUhYSaMXBUM1PbN_qU9Wxeo4gHC http://c...

Interestingly comet, 252P, which near perihelion showed a powerful outburst, increasing its brightness by more than 5 magnitudes, making it visible to the naked eye from the southern skies.Here while "flying over" the Pipe Nebula, this perspective makes it almost 3D the picture. https://l...

Hello everyone. This time it's not an image only mine, but a picture made by summing the work more Italian and foreign amateur astronomers and then elaborated by Giuseppe Donatiello. Thanks to the sum of many pictures you could get a high signal-to-noise ratio, so as to highlight all the plots of t...

I had an incredible fortune to photograph the disconnection of Comet C/2014 Q2 Lovejoy on January 8 to 19:33 TU :D . This disconnect was due to the activity of the Sun these days,at PA 160 seems visible beginning of tail of dust https://lh5.googleusercontent.com/-jNn38RSW3O4/VLDngoccgtI/AAAAAAAAIIY...

Beautiful new meeting of this sky's gypsy :D , waiting for her maximum approach to the god of war: Mars.

I love the comets, are now more than a decade that the photographer them and every time are able to impress me with their beauty or conjunctions with other objects in the sky. Today the Comet C/2014 E2 Jacques was near the open cluster Collinder 399 :) https://lh6.googleusercontent.com/-C-TKHTvF1PQ...

you will find me presumptuous :D , but this mosaic I find very nice almost 3D: there's the Comet C/A1 Siding Spring 2013, two big globular clusters (Ngc362 and 47 Tucanae) and our satellite Galaxy the SMC https://lh3.googleusercontent.com/-0uT7rgL8KJE/VAK_oPD65hI/AAAAAAAAH7Y/NEowzYz6cgA/w914-h829-n...

the comet C/2012 K1 Panstarrs, today 2 may,is about 2 degrees north of the interacting galaxy M51. the comet is showing more and more activities, with a nice tail of dust, a large coma and a faint ion tail. :D https://lh4.googleusercontent.com/-EKWHFeATScE/U2OA7t826fI/AAAAAAAAHYE/eqTriP858R0/s512/C...

comet C/2012 K1 Panstarrs already a few weeks after its discovery had shown a strong activity, measured with a big af(rho) value . In recent weeks the dust production declined, but has begun to show a good gas activities with a more extended coma and an ion tail, for now still weak...but there are ...
