There was a nice hedgerow prominence on the Sun today. I didn't have time to do the whole disk but I got the good bit.
The white dot in the top right is the size of Earth at this scale and the prominaence is about 200,000km high.
Taken with a ST-80 scope (400mm f/5) and Quark Chromosphere H-alpha filter. QHY5Lii mono camera.

I appreciate the scale of earth in the image. Amazing image.

Not sure how I missed this beautiful shot Steve. Does the Quark a herschel wedge diagonal?

Thanks knak & Dan.
For scope apertures of 80mm or less, the Quark just goes between a standard diagonal and the eyepiece/camera. There's no other filter or light reduction (eg Herschel) involved. It sure feels odd taking off the white light filter and putting your eye up to the eyepiece.

Amazing shot, Steve!

Out of curiosity, what is the typical lifetime of a prominence such as you've captured in this image?

Thanks for the comments.
That particular region was active like that for several days. Most normal sized proms come and go over a day or so. You can certainly see them change in shape and size over an hour.

Fantastic shot Steve. Thanks for sharing and the details. I've never personally viewed the sun in H-Alpha, only white light so the info on the length of time it's visible was eye-opening. No pun intended....
