I did this:
It’s a focal length blend with the sky from 10 tracked exposures, 2 minutes each with an 135mm equivalent lens and the foreground one 1 minute exposure with a 35mm lens equivalent.

Thanks @HIRAM for the heads up (literally 
! I’ll try capturing tonight, let’s see how it goes…

Last night was a no-go due to rain showers, that aren’t due back until at least one more day, hopefully. Scientists are warning the public it’s not visually spectacular, and really requires at least binoculars to appreciate, and that the images seen in the media are time-elapsed. One term I heard was “glowing frozen space sponge” (asteroids being relatively regarded as space pillows).

That’s an accurate description of what I saw with my small refractor
As usual pictures look much better than what you can see live, though it’s not quite the same experience IMHO.

Here’s mine out on the eastern plains of Colorado. It has been super cloudy here as well. Very cold out there in the single digits (Fahrenheit) with wind chill. Probably would have been bearable without the wind.
This is with my hydrogen-alpha modified Panasonic S5 with the 70-300mm lens at 300mm, f8, iso6400. 50x20s frames tracked. Processed with Siril and Darktable.
Bonus Milky Way panorama. Not the best stitch by hugin, but good for initial stitch. Processed with Sequator, Hugin, and Darktable. A few further tweaks with Gimp.
The friend I went with just got the new Ford Bronco. He’s been waiting over a year for it.
modded S5 + Sigma 14-24 @ 18mm. 6 panels: 4x20s, f2.8 iso4000

SouthEast UK: Clear skies, not very cold at 5 deg C but seemed worse. Loads of streetlights. Couldn’t find anything green with a tail by naked eye or binoculars, but this chap seemed the most promising. Nikon D800 on wibbly tripod, 58/1.2 Noct-Nikkor, ISO 100, 8s at f/1.2. Processed with:

…and here in Louisiana, USA, it’ll be completely clouded over and raining until Friday at the earliest. By when it will be nearly full moon. Arghh… it’s the astronomer’s life.
I sold my 100mm f/9 semi-APO refractor back in the summer, but I have a nice little 150mm f/6 Newtonian OTA (in its place on my iOptron AZ Mount Pro) that would be great for this comet. It would also be easier to set up than my 300mm f/5 Dobsonian. Actually my 80mm f/7.5 achro would be best, probably.
But it’s all academic until stars replace clouds at night…

I’m afraid you’ll have to settle for 99mm. 
You’re in luck this was a test shot trying to locate it at 99mm, 10s, f5.6, iso12800. This was just a quick edit in Darktable.

This is beautiful. I should really make the effort and drive to the mountains instead of lazily trying from the balcony
For reference, mine was with a Pentax k5-ii with a 55-300mm at 300, about 40 light frames at 6seconds, f/5.8, iso6400, processed with Siril and finished in art

Ah, yes, thanks, @HIRAM. I had never heard of Boötes, but knew about Arcturus from somewhere. You can tell I’m not an astronomer.

Oh yes. Same here in Germany.

I don’t think it’s going anywhere real soon… ack! It sucks living near sub-tropical waters.
Movement is east-northeast.

Thanks! It was hard getting out of a warm bed a little before midnight to travel 1.5 hours to this location. I was kind of lazy since my friend offered to drive. I also had some problems with my camera initially. The focus ring wasn’t working for manual focus until I re-attached the lens. That problem wasted a good 15 minutes fiddling with that.
Does your Pentax have the astrotrace functionality?
Well I wish I was that lazy…
Yes, I have the o-gps accessory that I got very cheap in like new condition (that’s the great thing about Pentax, everyone wants to get rid of them it definitely helps, but it doesn’t do miracles. 6 seconds is the upper limit on a 300mm lens, and even that already starts showing a bit of trailing. But certainly better than nothing
Here my version, monochrome, shot sunday.
Setup:
FS-60CB + 0.72x reducer: f4.2
Camera: 2600MM, L filter Antlia

Very nice. Any info on the equipment used and other tips that you might want to share?
