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.

Conditions weren't amazing today, but I hadn't been out imaging in awhile so I took some images of these massive sunspots. Now I just need this wildfire smoke to clear out!

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!

Sun rising on improved processing
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.

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.
