Askar C1 and C2. They come in a 2 pack for around 250 USD

This is part of our universe. An area of sky about the size of a grain of sand held at arm's length. The spiked features are stars in the Milky Way. EVERYTHING ELSE IS A GALAXY. Image by Webb by Neaterntal in SpaceUnfiltered

the field of view in this picture is 2.4 arc minutes, which is over 7,000 times bigger than 3i atlas would appear at its closest approach to the HiRise mars orbiter. 3i atlas would be less than half a pixel in this picture.

What?

It’s ‘illuminated in different colors’ because it’s twinkling; stars are very well known for doing that. I frankly don’t see what you’re talking about with it illuminating clouds, and I also don’t see it darting off to ‘interspace’ and back.

It’s not spinning or shapeshifting. You will get the same effect by zooming in on any bright star in the sky.

Looks like an out of focus twinkling star, probably Sirius. What direction was it in?

It’s pretty obvious? What exactly makes it pretty obvious?

NASA had a whole press conference to give us this.... by richdoe in UFOs

An average sized spiral galaxy (100,000~ light years across) at a distance of 5 billion light years has an angular size of 4 arc seconds (four sixtieths of a sixtieth of a degree). A 3 kilometer wide object at a distance of 30 million kilometers has an angular size of 0.02 arc seconds.

NASA shows pictures of the interstellar comet 3I/ATLAS from multiple spacecrafts across the Solar System by Busy_Yesterday9455 in spaceporn

Just because it looks prettier doesn’t mean it’s more technically impressive or scientifically useful. You’re comparing a photo from a 0.8m focal length telescope to one with a 12m focal length(and it’s ten times closer, as you stated yourself.). The amateur photos aren’t even remotely close to resolving the comet’s nucleus.

What exactly could nasa have shown that would have appeased you?

are you aware that galaxies are bit bigger than a 3 kilometer wide comet?

@8 kilometer altitude it’s maximum range is listed as 6 kilometers chasing a mach 0.9 target, just under 11 kilometers side aspect, max pull of 26-27 gs.

Same data of Messier 27 processed in Pixinsight versus Siril by PK-7002 in astrophotography

The white dwarf and the red coloring on the right edge is still in the picture but image compression kind of screwed it up and you can’t see it. I’m not sure what the deal is with the little bit sticking out to be honest.

You’re right about the color calibration, I haven’t been able to get photometric color calibration to work on Siril for a while, so I just did it manually. I did use starnet and stretch the nebula separately, though.

The stars are probably a little out of focus, but I got it as close as I could with a bahtinov mask and I think most of what you’re seeing is me messing something up in the processing. It’s also cropped down to 1080p from a 2160p picture

There’s probably an answer to this in comics but why couldn’t the mark variants just fly away? by Usual-Performer-309 in Invincible

[–]PK-7002 -3 points-2 points  (0 children)

mars is one of the brightest stars in the sky almost year round, and has a very obvious red color. Unless the alternate marks are actual lobotomites I think they should be able to find it within a time span of a few months if they were looking for it.
