I photographed the comet both Fri and last night. If you are in a dark enough area it can be seen with the unaided eye. As for the lens, it's at least a 20 year old 400mm f/2. It worked just fine.

Thanks Bob. I think I've decided that there's a thin cloud layer where the comet's supposed to be that I can't see when it gets dark. I can't see any stars in that area either.

From the videos I've seen on youtube it certainly looks bigger than a star. Looks easy to spot with naked eye.


I forgot, set your ISO at least 3200 or more to locate it, then you can play with that also after you find it.
I focus on a bright star using live view if your camera lets you. Make it as small as possible, and you should turn off IS while on tripod. Go for it.

Even here in Western MD at a dark site the comet is hard to spot naked-eye before 10 p.m. Binocs will help greatly in the endeavor to first locate it. Around 10:30 it will have gotten dark enough to easily see without the binocs. Keep in mind that as the evening progresses the comet will get closer to the horizon and settle into the atmospheric haze usually present. To get your focus set (if you are using a lens w/o markings), focus on Jupiter, which should be directly behind you and v-e-r-y bright; if you have good focus you should be seeing several of the 4 Galilean moons with no problem. I've attached a jpg from Stellarium showing the comet's location thru the 23rd of this month, at which time the Moon will start to interfere with observing as it goes from new moon to 1st quarter. While I'm in Western MD, the orientation of the comet in relation to the Big Dipper will stay the same from any observing site. What will change though is how high the comet appears above the horizon from your location (if you're further north it will be lower, further south it will be higher). Another tidbit, a closed fist at arm's length is about 10 degrees and the distance between the 2 end stars of the "pot" of the dipper is 5 degrees, useful info in judging the comet's position. And those brighter stars shown in the stick figure are all naked-eye.

I’ve been photographing the comet for the last 4 nights. I would estimate the comet including tail subtends about a 5 degree arc in the sky. Not sure how to estimate size at arms length. You do need dark skies preferably without city light bubbles. When searching for it under less than ideal conditions sometimes averted vision may help you to find it. However, if you have a good idea where it’s supposed to be and you’re using a wide angle lens, just take the picture to see if its there. D500 with a 35mm f1.8 iso 800 @ 8 sec should reveal it, then adjust from there.

Here's a photo I captured of the comet on the evening of the 15th, my second shooting session for the comet, having been out at 4 a.m. that morning doing the same thing. While this image was taken around 10 p.m., the comet looked nothing like this naked-eye, and the sky certainly did not have those colors. Even with averted vision, it was all I could do to see the "head" of the comet at this time and only located it so I could orient the camera after I had spotted it in my 7 x 35 binocs. It goes without saying that I was using a tripod for this 4 second exposure. Good luck and clear skies!

Shot this last night. SOOC. Best viewed in a dark room. As with the Hogrider's post above, this is not what it looked like to the naked eye. The scale is about right, but it is much dimmer, it was much harder to see with the naked eye.

I've seen a couple of really good photos of the comet, taken from Glendale, which is right next to Los Angeles. So, if it's a "hoax", it's a pretty good one.

He said "just kidding" in the original post.

Im haven't tried the hi res mode on my em5 2 yet because I've been using some old Nikon glass that probably doesn't have enough resolving power to take advantage of it. I just ordered the m zuiko 7-14 2.8.
I thought I read somewhere that a firmware update to the em1 2 would take a separate exposure to combine in camera with the hi res shot to compensate for any subject movement. It would be at the camera's native resolution but I guess if you didn't pixel peep close enough you wouldn't notice.
My question is to anyone who has the em5 2 if that firmware update applies to it? I know I could always do it manually in PP, but would rather have the camera do it for me.
Thanks in advance for any replies.
Just kidding about the comet, but I'm becoming frustrated in trying to see it. I have the Stellarium app on my iphone and have pinpointed where it's supposed to be. What's the best time?

Take a look at this photo of Neowise made on the 17th in China.

I Can tell you this about viewing. If you don't have dark skies forget it. You just wont see it. The pictures I've taken of it look so much more vivid than I could see in person. You almost have to strain to see it. It does NOT come up from the horizon, it just magically seem to materialize about midway between the bottom of the Big Dipper and the horizon once its dark enough. Initially when you see it, it looks like a faint star with a slightly smeared tail. At first I thought it was a bug splatter on my windshield. Size-wise, its like any other star in the sky. The amount of tail visible depends on how dark it is.

The good news is: once you see it, you can't un-see it ! It doesn't seem to move much either. Stays in one place for quite a while until it fades away. Total viewing duration maybe 1-1/2 hrs maybe more.

I found it very difficult to focus on it because it was so faint, I could just barely see it in the viewfinder of my D810

Hope this helps

This is a good description of it. Looks much more prominent in photos or video.

At least here in the Western US the best time to see it now and in the next couple of days is ~1.5 hr after sunset. Look for it in the NW sky, ~30 degrees above the horizon. Note that if you live in an area with significant light pollution it will not look like much at all. This is my case and I could see it well with binoculars, but not or just barely so with naked eyes. But it shows up nicely on pictures (expose for a couple of seconds but not much longer, in which case it becomes blurry due to Earth/comet motion).

I am an Em5ii user. I do not THINK hi res is to deal with slight subject movement, as would be perceived by the camera and the comet. I am trying to figure out some way to use live comp feature of the camera which would allow a streak of the comet over other lighted subjects or even light painting. Im also thinking time laps might be kind of cool.

i know he did. But, in reality, I'm a miniture photographer for the most part and I got this photo of Neowise last night here in San Diego. No hoax. Canon EOS M6, 22mm F2 prime asp-c; F2.7 25 sec., ISO 120.
