There is a new small active region AR965, this time I am too lazy that I didn't open the window glass, for my daughter is also inside doing her summer homework and playing piano (with air conditioner), don't want her to suffer the heat with me. Without her, I won't even turn on the fan to avoid any local seeing issue.
I'm just setting my Borg 45ED II on the 410 head on a small tripod, so no tracking.
This is an excellent example to show that window glass is a great blur filter.
