A Solar Fourth of July Session

This 4th of July brought a bright day and the promise of some decent imaging of the solar disk....and I was not disappointed. Atmospheric conditions were good and steady for the most part.
Using the C102 refractor with full aperture Baader solar filter and the 40mm Coronado H-Alpha scope, I set just outside of my garage and had about 90 minutes before I would lose the Sun behind my neighbors roof line...
The full solar disk was displaying very nice sunspots, with definitive inner and outer details... I could even make out some penumbra arcing. Taking the first shot at prime focus, I switched over to eyepiece imaging, switching between the 2" MaxView II and the 1.25" adjustable zoom Zhumell eyepiece, (both screw into the T-adapter on the Canon T5i.) I prefer the look and contrast of the yellow filter over the naked shots...

Punching the magnification, I was getting nice isolated views of major sunspots, better than the image capture...
Here, using a 6mm 1.25" eyepiece, I was pushing the resolution of the scope.
Switching to H-Alpha...
Wonderful Faculae and prominences were there for there for the taking, much better visually than what is represented here. At 40mm, the aperture is quite limited in resolution, but even still...
With that, my 90 minutes of solar time was over, as the solar disk slid away from my angle, but I did have some passerbyers who desired a peek at the face of the Sun...

...and my well lubricated new friends offers the local Astronomer Tributes of alcohol...
I don't do enough solar imaging....
