20190111 Sun

This is the first imaging session for 2019!

First up is a full disc shot at 0721 (UT), foggy sky but rather nice seeing.  The solar surface remains inactive, note the bigger prominence on the 9 O'Clock position.


Close up at 0726 (UT), higher gain faster shutter, higher fps as a result:


Another close up at 0729 (UT), lower gain slower shutter, lower fps as a result, but less noise:


For better seeing, we don't need high fps or faster shutter to freeze seeing... slower shutter and lower gain means less noise!
