The last couple of weeks have not been good for observing. When the sky was clear enough to try to observe, there was heavy haze and awful seeing -- even the moon at very low powers was not worth viewing. I have enjoyed viewing the sun with my 80mm f/15 refractor and new Quark Ha filter, however. There have been some amazingly large prominences showing so much detail, and today a gigantic arched prominence from two which had merged. My Byers mount should arrive to me next week, and I'll work to set it up in the next couple of weeks to take more advantage of views. The next several days will have poor transparency and seeing, though fingers crossed next week will have some better conditions.
Last night was the least-bad night, with moderately good seeing 6/10, but with heavy haze and a bright, nearly full moon hurting fainter stars. I used my 7-inch mask for views of some easier Struve and other pairs, finishing with the moon.
