Beauty Timelord.

One of mine from last night, taken in a very dark spot. Processed a bit to remove noise and haze and added a bit of blue temperature.

Despite being into astronomy, I only found out about NEOWISE on Tuesday, when the local weather forecast mentioned it!

But got a nice view of it last night from the garden, first clear night all week. Nice view in my Carl Zeiss Jena 10x50s! I've got a few really close street lights, but could see a nice tail about half the length of the tail in that image above.

How many of those you got? Did you stack? If not, you should.

Owain Taggart · Jul 24, 2020

Not all that many, I'm afraid. This was one of the better exposures before the clouds rolled in. And stacking is something I never really got a handle on.

I had the opportunity to shoot with a cool widefield lens in a relatively dark spot last night.
I have other non processed shots, but I think this is the best one.

that’s what recent studies suggest

I don't think i've shared this image of the Trifid Nebula (M20) yet.

Catching up on my backlog of images.
Here is my fully processed version of the Pinwheel Galaxy (M101) in Ursa Major.
This was my most ambitious project yet, with 2.5 hours of integration time taken over 4 nights.

Been doing astrophotography for almost a year now.
I made an anniversary collage for that milestone of my best deep sky shots.

Edit:

made a revised version as a bit of a mock calendar title page:

A widefield shot aimed at the zenith at the time.
It shows the Milky Way region around Cygnus.
The purple tint is not natural, of course, but I kind of like it as an artistic element.

Dumbbell Nebula - M27.
A planetary nebula, which means, its a remnant made of gas and dust of a dying star blown out into space.
A hot white dwarf remains at the center producing the radiation that lights up the nebula.

There was a haze in the air the other day and was lucky enough to see this sun and have my camera with me. I could look at it. It's the first time I experienced this. But anyway, I got numerous shots like this. The only editing I did was cropping and spot fixing (damn dust).

I'm calling it Tatooine.

That's a fairly good shot, Gordie. Is that a plane on the right?

Timelord79 (he/him) · Sep 27, 2020

Orion has finally returned to the night sky and here is my first short visit this year. I hope to add much more data and continually improve it.
Compare it to last year's version which I posted prviously in this thread.

Owain Taggart · Sep 27, 2020

Amazing. Doesn't it make you feel fuzzy inside?

Neutron star collisions build gold by briefly smashing protons and neutrons together into atomic nuclei, then spewing those newly-bound heavy nuclei across space. Regular supernovas can't explain the universe's gold because stars massive enough to fuse gold before they die -- which are rare -- become black holes when they explode, said Chiaki Kobayashi, an astrophysicist at the University of Hertfordshire in the United Kingdom and lead author of the new study. And, in a regular supernova, that gold gets sucked into the black hole.

Neutron star collision going on in video..

I think Hubble showed a fading supernova time lapse recently...forgot the link.
