I can't play at night so...
Canon 300mm L with 1.4 extender on Canon 7D for the .6 crop factor.
Download and zoom will show the pairs. Most sunspots are not singles but doubles somewhat like battery terminals, they go from one to the other to make the spot.
Right after I shot this the hole closed and back to clouded over.

Sounds like a hole in one Jim :P Nice job.
And that's interesting I did not know that fact.

Nice shot Jim and I learned something I didn't know. Very cool. What kind of filter are you using?

Thanks Craig.
Here's the better explanation.
From Wiki..

"Sunspots are temporary phenomena on the photosphere of the Sun that appear visibly as dark spots compared to surrounding regions. They correspond to concentrations of magnetic field that inhibit convection and result in reduced surface temperature compared to the surrounding photosphere. Sunspots usually appear as pairs, with each spot having the opposite magnetic polarity of the other."

Thanks Northcoast.

I make all of my filters from Baader visual ND 5 film.
I have not found a better or cleaner filter material.
I have thought about using the photographic ND 3 but have not sprung for the film and I don't know if it would make that much difference since I am adjusting exposure manually.
All of my filters are on the objective side of the lenses not on the ocular. That makes it possible to manually sight and focus my camera.

Thanks for the thumbs up.
Not as nice as the one during the eclipse but still, not too bad.

Great shots, I have done a bit of research about solar photography. What I have found, is that the Baader film is hands down the best aftermarket solution, as far as the single filter solution. I have not read much about people using regular ND filters, and if I was to try I would definitely use the live view instead of the viewfinder, for safety reasons.

The solar filter material/film or glass used for viewing the sun are usually considered white light filters, baader and I'm sure others also makes narrow band filters for solar viewing/imaging the two I can think of off the top of my head are the Continuum and Calcium, which help bring out different aspects and detail, I assume, since I have never used any of these items.

One of the things I thought about getting was the Coronado Solar Telescope. That lets you see in Hydrogen Alpha and pulls in the flares. It has limited use and I was afraid I would not get as much use as I have with the other scopes.
I might be wrong and might someday change my mind.
