While I don't think I'll be able to capture anything, going to try to get a photo of Comet Nishimura after sunset tonight. Likely going to be too bright and too much low level ground clutter, but worth the attempt. Looks like my only chance is right at Sunset (so maybe 7pm - 7:20pm ? ) #CometNishimura #AstroPhotography

I've not managed to get a look at #CometNishimura. Does anyone have photos to share?

Newly found comet now visible to naked eye in ‘once-in-a-lifetime’ event

Sky-watchers are getting a “rare and exciting opportunity” to see a comet with the naked eye in a “once-in-a-lifetime” experience, according to astronomers. Comet Nishimura was discovered only in August but will be closest to Earth in a week’s time – just before dawn on Tuesday September 12. The object, which is travelling through space […]

See it now, or you'll have to wait until the 2450s. They said the same thing to Galileo, so get on it.

Comet #Nishimura (C/2023 P1) the morning of 9 Sep. from near Vantage, WA. Shot with my #Dwarf2 (50 x 10s exposures) aligned and stacked with #Siril. Thanks for stopping by, you green beauty! #DwarfII #AstroPhotography #Astronomy #CometNishimura

#CometNishimura is becoming brighter and brighter with every day and it reached "naked eye visibility".

But where is the #comet? When do I have to look at which direction?

Fear no more. I created 2 YouTube shorts to show you how to plan the observation using @StellariumDev

I'm not an astrophotographer, but when I'm at a dark sky site and there's a comet, I take a stab at it! This was taken from a sand dune in the Coral Pink Sand Dunes state park in Utah. #CometNishimura #astronomy

I decided to try to get a photo of #Comet #Nishimura this morning. Haze, smoke, clouds, and the glow from Omaha just about thwarted me, but it looks like I managed to capture #CometNishimura in the last photo before I ran out of darkness.

New 'potentially interstellar' comet will be visible to the naked eye next month before leaving our solar system forever
Comet Nishimura has a hyperbolic orbit, which suggests that it may have come from outside the solar system and will likely be catapulted into interstellar space after slingshotting around the sun.
