Checking on the observed magnitude has been kinda interesting, even though I don't have the ability to really peer though the light pollution. Comet C/2025 R2 (SWAN) has been consistently brighter than predicted, flirting with being visible to the naked eye (under 6.5 magnitude), depending on the light pollution. Think I saw it hit 5.9 observed yesterday or the day before, which supposedly means all you need are binoculars to get a decent look at it.

As of a few min ago:

The other comet, that's from outside our solar system, is sitting at ~12+ magnitude, so pretty dim to us. I would assume it may need a professional or high dollar private observatory.
Only attempting C/2025 , in fact I have a few shots! I'll post something quick and dirty when I bring the telescope in. It's so low on the horizon to me and it's right as it gets dark (EDIT - Also I live in a bowl of mountains so low shooting is very tricky) so I'll be shooting over a few days. Good news is the lil Seestar can stack images on it! That will help me (hopefully) clean up the pics.

Lol I'm a dumbass - I thought it was Lemmon , it's not it's Swan (the farther one). Here is a pic straight off the app (not cleaned up) I'm too damn tired to try cleaning it up. I'll mess with it more tomorrow and over the weekend.

The Pacman Nebula or NGC 281 is a cloud of space gas and takes its name from the arcade game character. It is approx 9200 light years away from earth.

Processed using Siril, Starnet ++, and GraXpert with over 4 hours of 10 second exposures stacked. Images were taken with my trusty SeeStar S50.

Would you guys mind tagging me if something will be visible with the naked eye. Id like some of my friends kids to experience a comet when young.

The Hale Bopp comet was cool as shit in my teens.

I'd be glad to but I am striking out HARD. I live in the high desert and it's been overcast and fucking raining(?!!??) every night.
Supposed to be clear tonight so I'll check around 7PM PST. A6 Lemmon is supposed to be visible to me then.

I'd appreciate it. I don't know where to look to get the info and I often times forget. however, I was reading something last month and I thought they said we had a potential for 2 naked eye viewings coming up. Unsure how much truth there is to that but would be cool to see again.

If you are in the US look west just after dark to see A6 Lemmon. It will look literally like a fuzzy star to the naked eye. The other one would be hard to see naked eye, it's the green one I posted a few days ago.

EDIT: as far as an app - Stellarium (even the free version) will show you where both are.

Probably wont see anything like Hale-Bopp again in our lifetime. I don't think Halley's gets as bright as that comet got. Additionally, if you are stuck in a big city, you are pretty much fucked for looking at many/most celestial objects. Big Bend National Park is the closest "zero" light pollution spot for all of Texas and possibly some of the surrounding states as well.

Closest imitation would probably be camping in Big Bend during one of the heavy meteor showers (not sure what the meteor/hour rate is for any of them).

As for websites/apps, yeah, Stellarium is awesome for just looking at the current night sky and even watching satellites zip across. While I haven't used TheSkyLive.com until recently, it has some neat functionality. On the bar at the top-ish it has some handy shortcuts like what's visible right now and what's visible tonight (2025 A6 Lemmon wont show up on "visible now" because it's already under the horizon but will still be listed on "the sky tonight"). Also, the orbital visualization is cool. Set for DFW:

I looked where it said to look, but no luck. I'm going to set up my seestar tomorrow and see if I can get anything on it. Unfortunately It's low on the horizon exactly where the sun sets.

Outside of comets, a good way to get kids involved is to have them take a look at the four major moons of Jupiter, they are easily visible with just binoculars. You can have them make a drawing of the position of the moons and then do the same again a few days later so they can see they have moved. An easy way to replicate a major discovery that they will hear about in school.

Right now it's best visible in the morning but around Christmas it'll be in optimal position for viewing (directly opposite the sun, so it's visible all night and as bright as it gets)

It'll look something like this with binoculars. Most astronomy apps will show the current position of the moons too so the kids can look the names up on their phones.

Its not zero light pollution like Big Bend, but just about anywhere in west Texas is pretty good for star gazing. Cap Rock Canyons State Park is a nice little trip this time of year with some nice camping spots. Closer than Big Bend.

As someone who loves stargazing, you really are doing yourself a disservice if you never go to a place that has no light pollution. I have been to the big bend area and its great, but going to a spot in the pacific hundreds of miles from anything and looking up... seeing the milkyway the way our ancestors for millenia did is just amazing.

Who said I never go? Why are you always making shit up? I've been to BigBend half a dozen times and spent three summers in northern Montana.

I was speaking generally to others on the forum, it wasn't a personal attack at you.

I have to get myself over to Big Bend sometime soon while the border is sealed; it's on my bucket list.
Haha its not that sealed in the park. You can still wade across the Rio Grande just about anywhere. They leave little copper wire trickets out all over the place that you can buy on the honor system. What is sealed are all the exits, even before Trump, so its never been much of an entry point for illegals. Definitely worth the trip.

The stars I saw when we were out to sea and heading to Columbia were incredible. Never saw such a full sky in my life.

Death Valley is pretty dark too. I'm 2 levels from total dark where I live

Whomever wanted to know about comets, they are visible NOW. I have my Seestar up and it was getting shots when I left it. I'll get it in a few, I'm going to run out of horizon soon.

Do you run red lights outside at night I steady of normal?

Yeah, out on the Pacific Ocean in the dark waters, dry air and no moon, the sky becomes almost surreal looking. The best night sky I ever saw was about 900 miles west of Columbia. The great thing about a place like big bend is the dry air and elevation make it almost certain you’ll get a really nice view of the stars, and it’s a lot more accessible. I was actually an avid star watcher for a long time before I first saw the Milky Way hanging out in the sky visible to the naked eye, totally a mind blowing experience. Seeing a copper meteorite and a false sunrise were to of my other big ones I remember. The one thing I really want to see before I die is a supernova visible to the naked eye.
