Comet C/2018 N2 (ASASSN) was discovered a year ago and will reach perihelion next month of November, but will not go much inside the Solar System and will not shine more higher than magnitude 11. In this image taken on July 12, 2019 the comet is at magnitude 13, have not very gassy appearance but is already showing a nice dust tail. The brightest star is at magnitude 7 highlighting also in upper part the spiral galaxy NGC 1024, the bigest, although at least fifty small galaxies can be seen in this field with only 37 square arcminutes.

Comet C/2018 N2 (ASASSN) imaged on August 3, 2019, with a visual magnitude near 13 the comet shows its curved dust tail with an angular lenght of some 7 arcminutes. The brightest star into field is Omicron Arietis with a brightnes of magnitude 6.

Comet C/2018 N2 (ASASSN) image on August 10, 2019 with more resolution. With a slight increase of brightness until magnitude 12.5 its appearance barely has changed  with its 1 arcminute coma which contains a sharp central condensation and its curved dust tail with more that 5 arcminutes lenght.

Sorry, if you can not see images in my previous posts, I think is a problem with links https to my webpage, but the system of forum non permits to me edit the posts. Please, use the links in posts to see my images.

On September 7, 2019 the comets C/2018 N2 (ASASSN) and 260P/McNaught crossed in the sky on this field full of small galaxies in Aries constellation. Its minimal angular separation was only 10 arcminutes, although only due our perspective from Earth, as both comets were far away from each other; at bottom comet 260P/McNaught to 0.6 A.U. from us and at upper comet C/2018 N2 (ASASSN) to 2.6 A.U., two times the distance from Earth to Sun separates them.

Comet C/2018 N2 (ASASSN) imaged on September 1st 2019 with a brightness in magnitude 12. Since my previous image taken twenty days before, its coma has increase size from 1 to 1.5 arcminutes keeping a strong central condensation. Dust tail also increased lenght from 5 to 10 arcminutes.

Conjunction of comets C/2018 N2 (ASASSN) and 260P/McNaught on September 7, 2019. Photographed with a more sensitive camera than my color image taken at same day, this monochromatic version stand out dust tails details. Highlights inside tail of 260P (at down) is a bright central spine, due we are crossing these days the orbital plane of this comet and we see sideway the most of dust which are always concentrated in that plane.

Well done!

For some reason I was under the impression that cometary tails would be pointing in the exact same direction away from the sun during a conjunction. Turns out it's the fainter gas tails that would be more likely to do this, while the brighter dust tails captured in your image visually curve depending on both orbital mechanics and the direction of the sun. Thank you for sharing and giving me an opportunity to learn something new!

Exactly, ASASSN (at upper) is huge away than 260P (at bottom), is a very very deep perspective.
Thanks Anthony.

I can honestly say this is the coolest comet presentation I've ever seen! It was a comet (Hyakutake in 1996) that first stimulated me to get my own telescope (actually, my girlfriend at the time got me a broken Celestron orange C90 Mak that I upgraded to the C5/750 that I still own) and another comet (Hale Bopp in 1997) that inspired me to buy my first SLR camera (a Pentax Super Program) and a set of lenses to shoot it. So cometographía was the start of my AP over 20 years ago. And now seeing two long-tail comets together in a frame for the first time…well…that just brings out all sorts of gushy feelings and mexicanismos of surprise and joy.

 

Thanks for sharing!

 

Agradecidamente,
