Solar Surface in Ha and Ca II K August 10

This is my first post for the Sun in Ha and Ca II K. I was fortunate to get some blue sky today (although seeing was very ordinary) which may be the only day this week going by the current weather forecast.
For Hydrogen Alpha, I used a 60 mm Solar Max II as a single stack scope and for Ca II K, I used and Orion ED80T CF Triplet with a Lunt B600 Calcium K line filter.
