Solar - Show us your images of the sun

Nice lift off prom today! it will eventually be pulled back into the sun by the suns gravity.

Lunt ED102 telescope, Quark Gemini, ZWO ASI174mm camera, Skywatcher EQ6-R Pro mount. 1000 frames of the surface and 500 of the prom, each had the best 50 frames stacked and then combined in photoshop

Good grief! And taken with your own equipment? In our backyard?

Looking at the name of the file in the gallery - 10_26_14_AS_F50_lapl5_ap2793 - do (some of) these numbers have meaning in terms of what we are seeing on the sun in your image?

I should rename them but this way I can find them on my PC. the first 6 numbers are the time HH_MM_SS, then it is the number of stacked frames F50 not sure what the rest is.

I had a short hole in the clouds and got the shots. I know why they called this area "New England" we are cloudy all the time LOL

I was just wondering if it was a kind of short-hand for astro photographers.

As to the clouds, yep, know them all too well.

I'm no astronomer, so I hope this isn't a silly question, but, considering that the sun is not much more than a mass of swirling hydrogen and helium, does that swirling create any motion blur? I've really no idea how slow or fast the swirling is, or how the 93 million miles between us and it affects the image (though I appreciate that our atmosphere can make things tricky).

Our atmosphere is the limiting factor. the sun is rotating but I am normally shooting at 128 frames a second of the surface and 30 frames a second on the prominences so the sun isn't moving that fast, BUT our air is very unstable, think taking a picture of the bottom of a stream that is running fast with ripples.
The solar features are also constantly changing, not as fast that you can see them change but over the course of several minutes would will notice that they changed.

The sun today, which you like better Color or B&W

No favourite here. I'm blown away by everything you post here and in your other astro threads, color or B&W.

Wow Jeff these are amazing images...

The sun today. Rather nice prom and then AR4064, the active region, the filament (dark "stripe") will be called a prom when it reaches the limb of the sun.

The issue I had today was that my camera a ZWO ASI174mm was only running at 15 FPS rather than my usual 60-125fps. I think it might be the USB cable so ordered a couple new ones.

There you go again. Amazing images.

Sun in Calcium K, a different wave length than white light or Halpha. Shows different features

Sun in Calcium K

I had never even heard of that.

 

[Jeff WX1USN]

I had never even heard of that.

There are several wavelengths to shoot the sun in and they show different features. Personally I prefer Halpha which is known as Chromosphere mode, showing not just the surface features but the prominences on the limb of the sun. That is what I shoot most of the time.
