July 29 Sunspots

Unsteady Air!

Three sunspot groups marched in line across the Sun this morning. I was anxious to try my new camera on this parade, but the "seeing" was poor (the atmosphere was swirling). Here are my best three images:

The three sunspot groups barely fit within one field of view.

Here's the group in the upper right of the previous image.

Here are the two groups in the lower left of the first image.

These images were made with a DMK41 camera at the prime focus of a Celestron-8 telescope equipped with a mylar solar filter. Each image is made from a stack of hundreds of individual video frames.
