 On leave at home doing some solar imaging, seeing becomes slightly better, transparency similar.

0722 (UT), I managed to get full disc with the reducer at a longer distance from the camera.  Rich view and T-max was not tuned well so that the bright spot was apparent.


0730 (UT), taken with a 2x barlows.  Seems like the low transparency was killing detail.

I have conducted experience to use MONO16 instead of MONO8 but the frame rate was reduced to less than 10 fps with my slow notebook.  The SER file was not well processed as well, AS! support was less than perfect.

 Poor seeing, I guess 3/10 at best, transparency 5/10.


Better not to colorize it.
