Comet 2020 M3 (Atlas) in Lepus

Recommended Posts

This comet is low down in Lepus so a tricky one for me to 'see'. 

Small nucleus, large-ish diffuse halo which is asymmetrical.

...and now in Orion.

Taken from an EEVA session last night in atrociously windy conditions:

I had a look at M3 last night - very nice.

Great comet shots guys! No chance here at the moment. Is this one moving quite quickly? It seems to have moved from star-poor to star-rich and back to star-poor regions in just a few days. I do like the wide FOV in Orion.  Certainly the core motion in 2 minutes looks quite substantial in Mike's last shot.

It is.  If I simply use Jocular to play my 20 second subs then I’m watching a movie...

...any chance to output this from Jocular as an animated GIF?

Just tried the same as Tony and was posting when Tony's post came in. I detected movement after 15 secs (3x5sec subs). If I run the subs fast then it is indeed like a movie. Mike

Good idea. I will work on it...

Thanks to @Martin Meredith's exceptional speed and prowess with Jocular development / Python / kivi / ... I can present a movie of the other night's comet capture.

As an apology, I'd just mention that it was very windy and my star shapes/focus are usually better than this!

Further thanks to Martin for providing us with such a super EEVA tool.

Tony

More the prowess of the open source world!

I think animation is also useful for anyone coming at EEVA afresh to see the kind of rubbishy subs we often have to deal with, and how the magic of stacking & sub deselection can still lead to useful observations.

The distribution on the Jocular thread has been updated to include this feature.

and here is my version of the comet moving over 125 seconds. Mike

Caught up with it again this evening... much better conditions than previously:

I too could not resist another look at M3, last night. It is moving at about 15km/second and heading back out into the solar system.

This animation shows the movement over about 7 minutes.

Sorry about this. It's getting repetitive.

I, too, could not resist a look at Comet C/2020 M3 ATLAS. It was certainly not in Lepus last night. And I wanted to have a go with Jocular 0.3 and try the gif feature. So I'm afraid it's a jump on the bandwagon ten minute time-lapse of the comet.

I did have a look at some other things as well.

Regards

Mesmerising!

I know almost nothing about variable stars but I wonder if there are any really fast variations (though not so fast as the Crab pulsar) that could be visualised using this approach? Likewise, occultations by things other than our moon. Motion of the moons of Jupiter? How many pixels/minute? (displaying my ignorance here!)

Bill - I do like your animation - much better than mine.

Martin - moons of Jupiter - might see the movement -  image every 10 mins for an hour? - no idea.

Tony - like the wide fov and the streak effect

Satellites, for example ...?
