Imaging in a Sauna?  After my “daily exercise” of fast walking 2 miles at a 4mph pace and observing at 85 degrees in 93% humidity.  That’s what today’s session was.  Solar Activity is very low and we have a spotless Sun again for Spotless day 909 since Solar Max. The last spotless day we had on May 7th.  However, the filaments still remain. So today’s images of the full disk and close ups of the plages and filaments left.  Please note that the Ha close up of the Southern Hemisphere filaments is a wider FOV than my normal close ups.
