The Gravitational forces in the Universe are astounding!!!

Lunt80 Ha scope. ZWO ASI183MM-Pro camera Skywatcher SolarQuest mount.

@@FortWorthAstronomicalSociety Thanks very much. I have a Lunt 60mm double stack on order and have been wondering about the capability of the SolarQuest as the 11 lb capacity was a bit of a concern. I added the Solar Quest to my order based on the hope it would be ok after seeing it used with a smaller scope. Since I ordered it I have talked myself in and out of it several times lol. If it can carry your Lunt 80 then things should be good. Have you upgraded the tripod or left it stock?

@@antiquegeek The tripod is stock. I leave a battery on the bottom tray for more stability. The clutch needs to be fixed - it is a cardboard disk that will eventually fail. You can replace it yourself with better paperboard or felt for more friction. This was single-stacked for faster exposures, but double-stacked has more contrast.

If you look carefully, you can see the rotation on the zoomed-in edge views, from left to right. There are no coronal mass ejections visible in this short timelapse. Afterwards, there was one from the prom in the SW edge.

Forgive me if your comment is satire, but I suppose it can't hurt to point out that you can go about your normal activities on the day of the solar eclipse. The sun is no more harmful than usual. The only danger is in looking directly at the sun - something you naturally avoid doing every day of your life. Eclipse glasses are only necessary while you're actually looking at the uncovered or partially covered sun.

What you're looking at is a single wavelength of light being observed from the Sun called Hydrogen Alpha aka H(α) ( which is 656.3 nanometers in the EM spectrum ). It's basically a way to get around the intense white light washing out all the details of the Sun that you'd normally get from a regular white light solar filter. With a H(α) filter, all the " glare " gets blocked so you can see the full details of the Sun's surface features along with the prominences and plasma activity in the magnetic field lines. The only time you can observe prominences or particles following magnetic field lines in the Sun's atmosphere with no filter is during a Total Solar Eclipse.

There are many in our club who do solar imaging. Meetings are at 7pm on the third Tuesday of the month at the UNT Health Science Center Research and Education building, 1055 Montgomery St, Fort Worth, TX 76107. This was done with the Lunt 80mm. Make sure your etalon is tuned. I use a mono camera, 0 gain, 2.5ms to 5ms, depending on the sun's altitude. Focus on the edge of the limb first. Open the tuner, crank it all the way down, then open it back up slowly to about half-way. Stop when you get see a lot of contrast. I record an SER for 1 minute, then repeat over and over to get the timelapse. Stack each SER and take the best 5-25% of the images. Then process as you like. I have some action in Photoshop I use for automating hundreds of frames for color and clarity.

@@FortWorthAstronomicalSocietyAwesome! I am in Richardson myself and just ordered an Lunt 40!

I added links to the manufacturers in the description and a list of resellers.

@@FortWorthAstronomicalSociety Awesome, I appreciate the follow up! Just picked up a few pairs from Rainbow Symphony!

The sun's color is white, to our eyes. But we classify it as a "yellow dwarf" based on the temperature. For these images, we color them yellow or reddish so that our eyes are better able to see the contrast. For hydrogen-alpha images, the color really is a deep red, even deeper than the color we tend to use for aesthetics.

The realtime view is rather boring. It takes minutes to see changes happening, so slowly that we just realize something is different well after the event happens. The actual velocities are quite large, but the scale of the sun is even larger. An analogy is watching a hurricane from space. The winds are fierce at ground level near the eye, but from far away, the motion is barely perceptible, and only with a timelapse do some motions and patterns become obvious to us. Incidentally, there are a number of aurora videos that are not timelapses at all, but in realtime. Most people do not even realize it because we just expect the apparent motion is "supposed" to be slow.

@@FortWorthAstronomicalSociety Thank you. I know I'm unusual but barely perceptible is what I want, because it's 'real'. We've all seen time-lapse vids of plants dancing as they grow, but if one is very still, you can see it in real time, and I used to watch it (my sunflower greens, indoors/ no significant air movement), but you just have to be still and patient. Again, not for everyone, but call it an exercise in stillness.

You can actually see your plants grow? You must have some serious autism.

@@MountainMetaldo you watch paint dry too

@@REMdonor No, but I sometimes watch plants dance as they grow, normally only seen in time-lapse. It requires an unusually still mind, and body... and still air, of course.

I think the smaller the star, the more active it is unless it’s a white dwarf or black dwarf (fully dead star with no fuel left)

I recognize the video from Goddard

Yes, I was also feeling it beautifully frightening.

ASI183MM-Pro, no barlow.

Three hours in 8 seconds. Each clip is the same animation of the same 3 hour period, repeated twice for clarity, and zoomed in to focus on something specific.

Ecco tre ore in otto secondi😮

3 hours in 8 seconds. Each frame is a stacked image from 1 minute of capture. Each clip is the same animation of the same 3 hour period, repeated twice for clarity, and zoomed in to focus on something specific.

The earth's climate is dependent on many things, not only the solar flux. Greenhouse gases are a major factor in the average temperature of the planet. We can see this through geologic records, especially during the Snowball Earth periods, the Oxygen Crisis, etc. The End Ordovician extinction event had the uplift of the Appalachians, an increase in weathering and flow of minerals into the oceans, blooms of the plankton of the time, and sequestration of CO2 in their shells, changing the chemistry of the atmosphere and the oceans. The Late Devonian extinction event was caused by the growth and diversification of land plants, sequestering CO2 and generating rapid and severe global cooling. The End Permian extinction event was due to massive volcanic activity in Siberia. This caused global warming from elevated CO2 and sulfur (H2S) levels from volcanoes, leading to ocean acidification, acid rain, and other changes in ocean and land chemistry. The End Triassic extinction event was due to enderwater volcanic activity in the Central Atlantic Magmatic Province (CAMP) caused global warming and a dramatic change in the chemical composition of the oceans. End Cretaceous extinction event was due to the asteroid impact in Yucatán, Mexico, causing a global cataclysm and rapid cooling. Some changes may have already pre-dated this asteroid, with intense volcanic activity and tectonic uplift. Our planet is a complex system that is stable only in the short term, and is easily destabilized when just one or two variables are changed.

@@FortWorthAstronomicalSociety We we’re giving the short version comment, lol, you have good info there, However, the politics and fake msm news is brutal. Ie) carbon capture trying to lower C02 on earth reduces Plants and vegetation etc food growth. There already is a food shortage on earth in many regions. Plus we’re going into a mini ice ice age due to grand solar minimum. Suspicious Observers channel if you want some info on that subject

You can’t learn what you don’t want to know. 😢

@@terryatpi they also blames humans breathing now 🤪💭

You fell for it!😂 Sea kelp

Each frame is 1 minute of stacked images, then the frames were stitched into a sequence.

Stars are a balance between fusion energy trying to blow the star apart, and gravity trying to squeeze it together into a tiny point. The stars burn until there is an imbalance.

А потом нам говорят что в газовом шаре Солнце образовалась большая трещина. Как в газовом шаре может образоваться трещина? Это возможно только на твёрдой поверхности. Они сами не знают что такое солнце..

@@FortWorthAstronomicalSociety OKAY, i think I'm getting it, thx for that.

​@@Gora600 Coronal holes are not "cracks". Whoever used "crack" as a description was not being accurate in their description.

This, my friend, is what the sun really is: czcams.com/video/9uhiGOEa_pc/video.htmlsi=LgIikwiOzfapiqfq
