The Sunday Sun

Sunday afternoon was just perfect for solar imaging. I set up the PST-DS and mated it up to the DS 2.3+ with Barlow. The images below were 500 frame AVI's, stacked in Registax (the 150 best frames) and wavelet processed.

The first image is a crop of the larger, almost full disk image that follows it. It shows AR 2546--a large spot that could swallow earth, but which is also uncharacteristically quiet (no flaring).
