It’s the time of year for solar observing again, and there was a nice active disk yesterday in both H alpha and white light.

Here’s an image taken by the method I’ve been using for a couple of years now, using the DMK 41 camera in combination with the Lunt LS60 double-stacked to take an image in two parts and stitch it together. On this occasion I used DoubleTake for the Mac to do the stitching and balancing, and it does a good job.

Taken in mid-afternoon in warm conditions (27C), seeing was poor. (Click to enlarge)
