I had an opportunity to do some solar imaging on three straight days and it was really cool to watch the sunspots change in such a short period. Check out how the upper and trailing patches seems to materialize from nowhere and some of the areas shrank. Really cool!

Zoomed in to highlight the sunspot areas in each of three images. The first image has a single small spot trailing and nothing above. The second has faint spots above and larger spots forming to the left. The third image has lots of small spots in a cluster above the main group and the trailing spots are more spaced out.2025-06-23 - one large spot disappears around the right edge. Notice the absence of spots above and to the left of the clusters.2025-06-25 image with much larger and more complex trailing and upper spots2025-06-24 - upper and trailing patches start to appear

Summer is only a few days old here in New England, but wow is it hot this week. I left my scope out for some solar imaging and manage to snag some sunspots.

Monday dawned clear and bright so we set up the hydrogen-alpha solar telescope and recorded some image sequences. Today was a dull and cloudy day so we spent some time learning new processing techniques for our solar imaging and were rewarded with our best shot yet. We've a long way to go but we think this picture shows great progress!

Full disk image of the Sun in hydrogen-alpha light. Visible are surface granulation, filaments, sunspots, spicules, and prominences around the rim. The solar disk is a shade of yellow (false color applied) and the prominences are dark orange, all set against a black background. The result is a big improvement over what we have previously achieved thanks to Solar Toolbox for PixInsight.

The Sun in Hydrogen-alpha Light.

Monday dawned clear and bright so we set up the hydrogen-alpha (Ha) solar telescope and recorded some image sequences. Today was a dull and cloudy day so we spent some time learning new processing techniques for our solar imaging and were rewarded with our best shot yet. The processing of choice was Solar Toolbox — a script package developed for use in PixInsight software — just the set of tools we were looking for! We’ve a long way to go but we think this picture shows great progress!

The Sun Endures. The partly-cloudy sky today offered plenty of openings to deep blue sky, 26℉, and light winds produced good seeing for an interesting cluster of active regions!

AR3976 was reportedly the source of a powerful, sub X-Class flare January 31. The resulting CME is expected to narrowly miss Earth on February 3.

First image in monochrome, second image with false color applied.
The complete solar disk as recorded in hydrogen-alpha light. The “worm-shaped” shadows seen in several areas are filaments. The dark spots are, yes, sunspots. And around the rim or limb of the solar disk are seen prominences — geysers of solar plasma riding magnetic field lines before crashing back into the sun. False color applied.

In addition to photographing Earth’s Sun in white light nearly every clear day, we occasionally set up the heavy telescope mount and bring out the new hydrogen-alpha (Ha) telescope for a bit of visual observing and unique imaging. It’s a bit of work since, without an observatory building we usually feel we need to take down and store away the mount after each session, so we don’t do that every day.

On November 8 we had clear skies, good atmospheric conditions, and the inclination to do the Ha setup and were rewarded with splendid views plus our best Sun images yet.

Using a Barlow lens to zoom for a closer view, we see large and small prominences and hints of spicules along Sun’s limb, and several large filaments. The dark spots in the upper left-hand corner of this picture is a group of sunspots at active region 3889.

Across the solar disk were visible large and distinct filaments — prominence loops seen from “above” — as well as sunspots and swirling patterns in the solar atmosphere around them. All around the Sun’s limb could be seen prominences glowing against a background of black space. Some of the prominences, which are fountain-like sprays and loops of magnetically-charged plasma, were quite large.

A major part of producing good images is what happens away from the telescope. Our usual practice is to record video of the telescope view and use software, in the office, to sort through thousands of video image frames, then stack the best few hundred to form a single still image. The still image is then edited to bring out as much detail and tonal range as possible. This process, which is common in astrophotography, produces a sharper image than what might be acquired via any single photographic “snapshot” owing largely to atmospheric turbulence.

Using a Barlow lens to zoom for a closer view, we see large and small prominences and spicules along Sun’s limb. The dark spot just above the center of this picture is a large sunspot at active region 3879.

There’s room for improvement, and we’re seeing excellent progress, but the images shown here are our best yet of Sun in hydrogen-alpha light.

Note: H-a light is that which Sun is producing in its chromosphere — the solar atmospheric layer between the outer corona and the lower photosphere — and is invisible even to protected human vision and white light cameras. Specialized optics are required to block other wavelengths found in white light and allow observation of Ha. When we observe or image in white light, we’re actually viewing features such as sunspots while looking through both the corona and the chromosphere!

Safety Note: It is not safe to look directly at the sun without specialized eye protection for solar viewing, and safe solar filters for telescope, binocular, or camera use. Permanent damage to vision can result from improper viewing of the sun.

Very challenging in the strong wind gusts, but I grabbed some photos of the #Sun with the huge #sunspot group #AR13590 on the right side just with my Canon 1100D +300mm lens fitted with solar filter. Stack of 75 images #ActiveRegions #SolarImaging #SolarPhotography

Today a different approach of .
After 525600 minutes of collecting photons, my image of 2023 is ready.
The image shows the path of the sun above my backyard in over a period of 12 months.

Had one hour of clear sky in the morning here in Heidelberg and decided to use it wisely - here is an image of the sun in the very specific H-Alpha wavelength.

Did the classic mistake and buy new gear, had to wait weeks for the sky to clear...

Here's the final image from today's live stream. Stacked and post-processed in about 10 minutes.

Thanks to everyone who joined! Including that one flat earther 😅 I hope I answered all of your questions!

Successful live stream. Still going for a few more minutes but here is a side by side of the live Sun and a live processing I did.

Anyone interested in a live stream of the Sun in H-Alpha? I'm currently running one for the next hour or so: youtube.com/live/L9EK6WEG3s8

I published a video earlier today showing my entire solar photography workflow from start to finish. This image is the final result. My next todo item is to turn that massive prominence on top into a timelapse.
