The sunspots have been pretty sparse during this solar maximum. A few freckles popped up over the past few days, so I thought I'd take a shot.

Nice capture Jim! They do look good at the moment, don't they?

I also grabbed a shot with my 70-200 f/4L and home made Baader filter:

For some reason your sun is upside down. Oh wait.. It's where we were standing :) :) Good shot!

Did you colour your image at all? My Baader film filter produces white images.

Nice shot, lots of spots!

Wondering what kind of lens should I use for sun, will my Sigma 120-300 f/2.8 + 1.4x tc be enough (approx. 420mm)? How much do you need to crop it?

That will work. I'm using an EF 100-400L at 400mm.

For a size reference of what to expect, my captured images of the sun are about the same size as my 400mm images of the moon. So, look at your moon shots and that's about the size you can expect.
