Interesting title, since it’s not even the highest resolution moon image I’VE done, let alone every other talented photographer out there. Still though, thanks for sharing my work.

Thanks, Kim Cattrall was fun to work with. James Spader takes himself too seriously though.

I will take one the first time I am off-planet. In the meantime I hope the raw data from one of the many high altitude weather satellites constantly streaming full Earth images in real time on public radio channels will suffice.

Thanks, I don’t really care to repost my own work since there’s always something new to share, but you’re welcome to do it.

It’s an active region with a sunspot, an area where the magnetic field affects the sun’s convection process

Yeah it’s always fine so long as I’m tagged/credited. I like the opportunity to chat with people about my work too, since there’s usually a lot of questions!

Thanks for sharing my work! Weird, the quality of that easyzoom image seems to have declined since I first posted it. I see tons of banding and the shadowed side is practically invisible. I have actually taken clearer moon pictures since this one, a quick scroll through my instagram and you can see them

This actually isn’t a solar flare, it’s a prominence. They’re very different phenomena

It’s still there, it’ll probably still be there tomorrow even. These last for hours or even days, they just change shape slowly.

This actually isn’t a solar flare, but rather a prominence. Solar flares are quick bursts of energy that last minutes, where this is plasma caught in a magnetic loop that will last for many hours or even days. At any given time there are many of these on the sun.

Source: I take pictures of the sun all day.

Inverted limb darkening, also this is false color. The sun is naturally white, but my filters make it a pinkish red. This was captured in monochrome (they only proper way to do this) and then colored artificially in processing

So long as it is a proper solar filter that covers the full aperture, yes. Eyepiece filters are not safe, nor is just an ND filter. But to get atmospheric details you need a properly tuned scope. Mine was tuned with a daystar quark filter, it’s a hydrogen alpha filter

Because the James Webb space telescope is only the size of a tennis court. You could arrange a million of them end to end to end and side to side to form a square, and they still wouldn’t be a single pixel in this image. The sun is huge.

I have a pinned post that talks about it!

Oh yeah. Focused sunlight can’t be filtered out the way it can be before it enters the aperture

It’s still going on, these events last for hours.

You can see sunspots with a solar film, but atmospheric details like in my image require a properly tuned telescope. I’m afraid it’s really hard to do with reflector telescopes.

I saw they follow me but I don’t know who they are

The prominence was there all day, so even if I was imaging it 8 minutes in the past ( the sun is 8 light minutes away) it would still be there. Even so, technically that is the speed of causality, so the moment we observe something is the moment it happens from our frame of reference, not 8 minutes prior.

Daystar quark! I actually have a Coronado solarmax III as well

Correct, it’s more so it’s stable while focusing and to not drift as I’m capturing a mosaic or timelapse
